  • BOXED WARNING (What is this?)

    WARNING: RISKS FROM CONCOMITANT USE WITH OPIOIDS; ABUSE, MISUSE, AND ADDICTION; and DEPENDENCE AND WITHDRAWAL REACTIONS

    • Concomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of these drugs for patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients for signs and symptoms of respiratory depression and sedation [see Warnings and Precautions (5.1), Drug Interactions (7.1)].
    • The use of benzodiazepines, including alprazolam extended-release tablets, exposes users to risks of abuse, misuse, and addiction, which can lead to overdose or death. Abuse and misuse of benzodiazepines commonly involve concomitant use of other medications, alcohol, and/or illicit substances, which is associated with an increased frequency of serious adverse outcomes. Before prescribing alprazolam extended-release tablets and throughout treatment, assess each patient’s risk for abuse, misuse, and addiction [see Warnings and Precautions (5.2)].
    • The continued use of benzodiazepines, including alprazolam extended-release tablets, may lead to clinically significant physical dependence. The risks of dependence and withdrawal increase with longer treatment duration and higher daily dose. Abrupt discontinuation or rapid dosage reduction of alprazolam extended-release tablets after continued use may precipitate acute withdrawal reactions, which can be life-threatening. To reduce the risk of withdrawal reactions, use a gradual taper to discontinue alprazolam extended-release tablets or reduce the dosage [see Dosage and Administration (2.2), Warnings and Precautions (5.3)].
  • 1 INDICATIONS AND USAGE

    Alprazolam extended-release tablets are indicated for the treatment of panic disorder with or without agoraphobia, in adults.

  • 2 DOSAGE AND ADMINISTRATION

    2.1 Recommended Dosage

    Administer alprazolam extended-release tablets orally once daily, preferably in the morning. Swallow tablets whole; do not divide, crush, or chew.


    The recommended starting oral dosage for alprazolam extended-release tablets are 0.5 mg to 1 mg once daily. Depending on the response, the dosage may be adjusted at intervals of every 3 to 4 days in increments of no more than 1 mg daily. The recommended dosage range is 3 mg to 6 mg once daily.


    Controlled trials of alprazolam extended-release tablets for the treatment of panic disorder included dosages in the range of 1 mg to 10 mg per day. Most patients showed a response in the dosage range of 3 mg to 6 mg per day. Occasional patients required as much as 10 mg per day.


    The longer-term efficacy of alprazolam extended-release tablets has not been systematically evaluated. If alprazolam extended-release tablets are used for periods longer than 8 weeks, the healthcare provider should periodically reassess the usefulness of the drug for the individual patient.


    After a period of extended freedom from panic attacks, a carefully supervised tapered discontinuation may be attempted, but there is evidence that this may often be difficult to accomplish without recurrence of symptoms and/or the manifestation of withdrawal phenomena [see Dosage and Administration (2.2), Warnings and Precautions (5.2)].

    2.2 Discontinuation or Dosage Reduction of Alprazolam Extended-Release Tablets

    To reduce the risk of withdrawal reactions, use a gradual taper to discontinue alprazolam extended-release tablets or reduce the dosage. If a patient develops withdrawal reactions, consider pausing the taper or increasing the dosage to the previous tapered dosage level. Subsequently decrease the dosage more slowly [see Warnings and Precautions (5.3), Drug Abuse and Dependence (9.3)].


    Reduce the dosage by no more than 0.5 mg every three days. Some patients may benefit from an even more gradual discontinuation. Some patients may prove resistant to all discontinuation regimens.


    In a controlled postmarketing discontinuation study of panic disorder patients which compared the recommended taper schedule with a slower taper schedule, no difference was observed between the groups in the proportion of patients who tapered to zero dose; however, the slower schedule was associated with a reduction in symptoms associated with a withdrawal syndrome.

    2.3 Dosage Recommendations in Geriatric Patients

    In geriatric patients, the recommended starting dosage of alprazolam extended-release tablets is 0.5 mg once daily. This may be gradually increased if needed and tolerated. Geriatric patients may be sensitive to the effects of benzodiazepines [see Use in Specific Populations (8.5), Clinical Pharmacology (12.3)].

    2.4 Dosage Recommendations in Patients with Hepatic Impairment

    In patients with hepatic impairment, the recommended starting dosage of alprazolam extended-release tablets is 0.5 mg once daily. This may be gradually increased if needed and tolerated [see Use in Specific Populations (8.6), Clinical Pharmacology (12.3)].

    2.5 Dosage Modifications for Drug Interactions

    Alprazolam extended-release tablets should be reduced to half of the recommended dosage when a patient is started on ritonavir and alprazolam extended-release tablets together, or when ritonavir is added to a patient treated with alprazolam extended-release tablets. Increase alprazolam extended-release tablets dosage to the target dose after 10 to 14 days of dosing ritonavir and alprazolam extended-release tablets together. It is not necessary to reduce alprazolam extended-release tablets dosage in patients who have been taking ritonavir for more than 10 to 14 days.


    Alprazolam extended-release tablets are contraindicated with concomitant use of all strong CYP3A inhibitors, except ritonavir [see Contraindications (4), Warnings and Precautions (5.5), Drug Interactions (7.1)].

    2.6 Switching Patients from Alprazolam Tablets to Alprazolam Extended-Release Tablets

    Patients who are currently being treated with divided doses of alprazolam may be switched to alprazolam extended-release tablets at the same total daily dose taken once daily. If the clinical response after switching is inadequate, titrate the dosage as outlined above.

  • 3 DOSAGE FORMS AND STRENGTHS

  • 4 CONTRAINDICATIONS

    Alprazolam extended-release tablets are contraindicated in patients:


  • 5 WARNINGS AND PRECAUTIONS

    5.1 Risks from Concomitant Use with Opioids

    Concomitant use of benzodiazepines, including alprazolam extended-release tablets, and opioids may result in profound sedation, respiratory depression, coma, and death. Because of these risks, reserve concomitant prescribing of these drugs in patients for whom alternative treatment options are inadequate.


    Observational studies have demonstrated that concomitant use of opioid analgesics and benzodiazepines increases the risk of drug-related mortality compared to use of opioids alone. If a decision is made to prescribe alprazolam extended-release tablets concomitantly with opioids, prescribe the lowest effective dosages and minimum durations of concomitant use, and follow patients closely for signs and symptoms of respiratory depression and sedation. In patients already receiving an opioid analgesic, prescribe a lower initial dose of alprazolam extended-release tablets than indicated in the absence of an opioid and titrate based on clinical response. If an opioid is initiated in a patient already taking alprazolam extended-release tablets, prescribe a lower initial dose of the opioid and titrate based upon clinical response.


    Advise both patients and caregivers about the risks of respiratory depression and sedation when alprazolam extended-release tablets is used with opioids. Advise patients not to drive or operate heavy machinery until the effects of concomitant use with the opioid have been determined [see Drug Interactions (7.1)].

    5.2 Abuse, Misuse, and Addiction

    The use of benzodiazepines, including alprazolam extended-release tablets, exposes users to the risks of abuse, misuse, and addiction, which can lead to overdose or death. Abuse and misuse of benzodiazepines often (but not always) involve the use of doses greater than the maximum recommended dosage and commonly involve concomitant use of other medications, alcohol, and/or illicit substances, which is associated with an increased frequency of serious adverse outcomes, including respiratory depression, overdose, or death [see Drug Abuse and Dependence (9.2)].


    Before prescribing alprazolam extended-release tablets and throughout treatment, assess each patient’s risk for abuse, misuse, and addiction (e.g., using a standardized screening tool). Use of alprazolam extended-release tablets, particularly in patients at elevated risk, necessitates counseling about the risks and proper use of alprazolam extended-release tablets along with monitoring for signs and symptoms of abuse, misuse, and addiction. Prescribe the lowest effective dosage; avoid or minimize concomitant use of CNS depressants and other substances associated with abuse, misuse, and addiction (e.g., opioid analgesics, stimulants); and advise patients on the proper disposal of unused drug. If a substance use disorder is suspected, evaluate the patient and institute (or refer them for) early treatment, as appropriate.

    5.3 Dependence and Withdrawal Reactions

    To reduce the risk of withdrawal reactions, use a gradual taper to discontinue alprazolam extended-release tablets or reduce the dosage (a patient-specific plan should be used to taper the dose) [see Dosage and Administration (2.3)].


    Patients at an increased risk of withdrawal adverse reactions after benzodiazepine discontinuation or rapid dosage reduction include those who take higher dosages, and those who have had longer durations of use.


    Acute Withdrawal Reactions


    The continued use of benzodiazepines, including alprazolam extended-release tablets, may lead to clinically significant physical dependence. Abrupt discontinuation or rapid dosage reduction of alprazolam extended-release tablets after continued use, or administration of flumazenil (a benzodiazepine antagonist) may precipitate acute withdrawal reactions, which can be life-threatening (e.g., seizures) [see Drug Abuse and Dependence (9.3)].


    Protracted Withdrawal Syndrome


    In some cases, benzodiazepine users have developed a protracted withdrawal syndrome with withdrawal symptoms lasting weeks to more than 12 months [see Drug Abuse and Dependence (9.3)].


    Certain adverse clinical events, some life-threatening, are a direct consequence of physical dependence to alprazolam extended-release tablets. These include a spectrum of withdrawal symptoms; the most important is seizure [see Drug Abuse and Dependence (9.3)]. Even after relatively short-term use at doses of < 4 mg/day, there is some risk of dependence. Spontaneous reporting system data suggest that the risk of dependence and its severity appear to be greater in patients treated with doses greater than 4 mg/day and for long periods (more than 12 weeks). However, in a controlled postmarketing discontinuation study of panic disorder patients who received alprazolam, the duration of treatment (3 months compared to 6 months) had no effect on the ability of patients to taper to zero dose. In contrast, patients treated with doses of alprazolam greater than 4 mg/day had more difficulty tapering to zero dose than those treated with less than 4 mg/day.

     

    In a controlled clinical trial in which 63 patients were randomized to alprazolam and where withdrawal symptoms were specifically sought, the following were identified as symptoms of withdrawal: heightened sensory perception, impaired concentration, dysosmia, clouded sensorium, paresthesias, muscle cramps, muscle twitch, diarrhea, blurred vision, appetite decrease, and weight loss. Other symptoms, such as anxiety and insomnia, were frequently seen during discontinuation, but it could not be determined if they were due to return of illness, rebound, or withdrawal.

     

    Interdose Symptoms


    Early morning anxiety and emergence of anxiety symptoms between doses of alprazolam have been reported in patients with panic disorder taking prescribed maintenance doses. These symptoms may reflect the development of tolerance or a time interval between doses which is longer than the duration of clinical action of the administered dose. In either case, it is presumed that the prescribed dose is not sufficient to maintain plasma levels above those needed to prevent relapse, rebound, or withdrawal symptoms over the entire course of the interdosing interval.

    5.4 Effects on Driving and Operating Machinery

    Because of its CNS depressant effects, patients receiving alprazolam extended-release tablets should be cautioned against engaging in hazardous occupations or activities requiring complete mental alertness such as operating machinery or driving a motor vehicle. For the same reason, patients should be cautioned about the concomitant use of alcohol and other CNS depressant drugs during treatment with alprazolam extended-release tablets [see Drug Interactions (7.1)].

    5.5 Neonatal Sedation and Withdrawal Syndrome

    Use of alprazolam extended-release tablets during the later stages of pregnancy can result in sedation (respiratory depression, lethargy, hypotonia) and withdrawal symptoms (hyperreflexia, irritability, restlessness, tremors, inconsolable crying, and feeding difficulties) in the neonate. Observe newborns for signs of sedation and neonatal withdrawal syndrome and manage accordingly [see Use in Specific Populations (8.1)].

    5.6 Interaction with Drugs that Inhibit Metabolism via Cytochrome P450 3A

    The initial step in alprazolam metabolism is hydroxylation catalyzed by cytochrome P450 3A (CYP3A). Drugs that inhibit this metabolic pathway may have a profound effect on the clearance of alprazolam.


    Strong CYP3A Inhibitors

    Alprazolam extended-release tablets are contraindicated in patients receiving strong inhibitors of CYP3A such as azole antifungal agents [see Contraindications (4)]. Ketoconazole and itraconazole have been shown in vivo to increase plasma alprazolam concentrations 3.98 fold and 2.70 fold, respectively. 


    Dosage adjustment is necessary when alprazolam extended-release tablets and ritonavir are initiated concomitantly or when ritonavir is added to a stable dosage of alprazolam extended-release tablets [see Dosage and Administration (2.5), Drug Interactions (7.1)].  


    Drugs demonstrated to be CYP3A inhibitors on the basis of clinical studies involving alprazolam: nefazodone, fluvoxamine, and cimetidine [see Drug Interaction (7.1), Clinical Pharmacology (12.3)]. Use caution and consider dose reduction of alprazolam extended-release tablets, as appropriate, during co-administration with these drugs.

    5.7 Patients with Depression

    Benzodiazepines may worsen depression. Panic disorder has been associated with primary and secondary major depressive disorders and increased reports of suicide among untreated patients. Consequently, appropriate precautions (e.g., limiting the total prescription size and increased monitoring for suicidal ideation) should be considered in patients with depression.

    5.8 Mania

    Episodes of hypomania and mania have been reported in association with the use of alprazolam extended-release tablets in patients with depression [see Adverse Reactions (6.1)].

    5.9 Risks in Patients with Impaired Respiratory Function

    There have been reports of death in patients with severe pulmonary disease shortly after the initiation of treatment with alprazolam. Closely monitor patients with impaired respiratory function. If signs and symptoms of respiratory depression, hypoventilation, or apnea occur, discontinue alprazolam extended-release tablets.

  • 6 ADVERSE REACTIONS

    The following clinically significant adverse reactions are described elsewhere in the labeling:

    6.1 Clinical Trials Experience

    Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.


    The information included in the section on Adverse Reactions Observed in Short-Term, Placebo-Controlled Trials with alprazolam extended-release tablets are based on pooled data of five 6- and 8-week placebo-controlled clinical studies in panic disorder.


    Adverse Reactions Observed in Short-Term, Placebo-Controlled Trials of Alprazolam Extended-Release Tablets


    Adverse Reactions Reported as Reasons for Discontinuation of Treatment in Placebo-Controlled Trials

    Approximately 17% of the 531 patients who received alprazolam extended-release tablets in placebo-controlled clinical trials for panic disorder had at least 1 adverse event that led to discontinuation compared to 8% of 349 placebo-treated patients. The most common events leading to discontinuation and considered to be drug-related (i.e., leading to discontinuation in at least 1% of the patients treated with alprazolam extended-release tablets at a rate at least twice that of placebo) are shown in Table 1.

    There have also been reports of withdrawal seizures upon rapid decrease or abrupt discontinuation of alprazolam [see Warning and Precautions (5.2), Drug Abuse and Dependence (9.3)].


    Paradoxical reactions such as stimulation, increased muscle spasticity, sleep disturbances, hallucinations, and other adverse behavioral effects such as agitation, rage, irritability, and aggressive or hostile behavior have been reported rarely. In many of the spontaneous case reports of adverse behavioral effects, patients were receiving other CNS drugs concomitantly and/or were described as having underlying psychiatric conditions. Should any of the above events occur, alprazolam should be discontinued. Isolated published reports involving small numbers of patients have suggested that patients who have borderline personality disorder, a prior history of violent or aggressive behavior, or alcohol or substance abuse may be at risk for such events. Instances of irritability, hostility, and intrusive thoughts have been reported during discontinuation of alprazolam in patients with posttraumatic stress disorder.

    6.2 Postmarketing Experience

    The following adverse reactions have been identified during post-approval use of alprazolam and/or alprazolam extended-release tablets. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.


    Endocrine disorders: Hyperprolactinemia

    General disorders and administration site conditions: Edema peripheral

    Hepatobiliary disorders: Hepatitis, hepatic failure, jaundice

    Investigations: Liver enzyme elevations

    Psychiatric disorders: Hypomania, mania

    Reproductive system and breast disorders: Gynecomastia, galactorrhea, menstruation irregular

    Skin and subcutaneous tissue disorders: Photosensitivity reaction, angioedema, Stevens-Johnson syndrome

  • 7 DRUG INTERACTIONS

    7.1 Drugs Having Clinically Important Interactions with Alprazolam Extended-Release Tablets

    Table 4 includes clinically significant drug interactions with alprazolam extended-release tablets [see Clinical Pharmacology (12.3)].

    Table 4: Clinically Significant Drug Interactions with Alprazolam Extended-Release Tablets
     Opioids
    Clinical implication
    The concomitant use of benzodiazepines and opioids increases the risk of respiratory depression because of actions at different receptor sites in the CNS that control respiration. Benzodiazepines interact at gamma-aminobutyric acid (GABAA) sites and opioids interact primarily at mu receptors. When benzodiazepines and opioids are combined, the potential for benzodiazepines to significantly worsen opioid-related respiratory depression exists.
    Prevention or management
    Limit dosage and duration of concomitant use of alprazolam extended-release tablets and opioids, and monitor patients closely for respiratory depression and sedation [see Warnings and Precautions (5.1)].
    Examples
    Morphine, buprenorphine, hydromorphone, oxymorphone, oxycodone, fentanyl, methadone, alfentanil, butorpenol, codeine, dihydrocodeine, meperidine, pentazocine, remifentanil, sufentanil, tapentadol, tramadol.
    CNS Depressants
    Clinical implication
    The benzodiazepines, including alprazolam, produce additive CNS depressant effects when coadministered with other CNS depressants.
    Prevention or management
    Limit dosage and duration of alprazolam extended-release tablets during concomitant use with CNS depressants [see Warnings and Precautions (5.3)].
    Examples
    Psychotropic medications, anticonvulsants, antihistaminics, ethanol, and other drugs which themselves produce CNS depression.
    Strong Inhibitors of CYP3A (except ritonavir)
    Clinical implication
    Concomitant use of alprazolam extended-release tablets with strong CYP3A inhibitors has a profound effect on the clearance of alprazolam, resulting in increased concentrations of alprazolam and increased risk of adverse reactions [see Clinical Pharmacology (12.3)].
    Prevention or management
    Concomitant use of alprazolam extended-release tablets with a strong CYP3A4 inhibitor (except ritonavir) is contraindicated [see Contraindications (4), Warnings and Precautions (5.5)].
    Examples
    Ketoconazole, itraconazole, clarithromycin
    Moderate or Weak Inhibitors of CYP3A
    Clinical implication
    Concomitant use of alprazolam extended-release tablets with CYP3A inhibitors may increase the concentrations of alprazolam extended-release tablets, resulting in increased risk of adverse reactions [see Clinical Pharmacology (12.3)].  
    Prevention or management
    Avoid use and consider appropriate dose reduction when alprazolam extended-release tablets are coadministered with a moderate or weak CYP3A inhibitor [see Warnings and Precautions (5.5)].
    Examples
    Nefazodone, fluvoxamine, cimetidine, erythromycin
    CYP3A Inducers
    Clinical implication
    Concomitant use of CYP3A inducers can increase alprazolam metabolism and therefore can decease plasma levels of alprazolam [see Clinical Pharmacology (12.3)].
    Prevention or management
    Caution is recommended during coadministration with alprazolam.
    Examples
    Carbamazepine, phenytoin
    Ritonavir
    Clinical implication
    Interactions involving ritonavir and alprazolam are complex and time dependent. Short term administration of ritonavir increased alprazolam exposure due to CYP3A4 inhibition. Following long term treatment of ritonavir (> 10 to 14 days), CYP3A4 induction offsets this inhibition. Alprazolam exposure was not meaningfully affected in the presence of ritonavir.
    Prevention or management
    Reduce alprazolam extended-release tablets dose when a patient is initiated with ritonavir and alprazolam extended-release tablets concomitantly, or when ritonavir is added to a regimen where alprazolam extended-release tablets are stabilized.
     
    Increase alprazolam extended-release tablets dosage to the target dosage after 10 to 14 days of dosing ritonavir and alprazolam extended-release tablets concomitantly. No dosage adjustment of alprazolam extended-release tablets is necessary in patients receiving ritonavir for more than 10 to 14 days [see Dosage and Administration (2.5)].
     
    Concomitant use of alprazolam extended-release tablets with a strong CYP3A inhibitor, except ritonavir, is contraindicated [see Contraindications (4), Warnings and Precautions (5.5)].  
    Digoxin
     
    Clinical implication
    Increased digoxin concentrations have been reported when alprazolam was given, especially in geriatric patients (>65 years of age).
    Prevention or management
    In patients on digoxin therapy, measure serum digoxin concentrations before initiating alprazolam extended-release tablets. Continue monitoring digoxin serum concentration and toxicity frequently. Reduce the digoxin dose if necessary.

    7.2 Drug/Laboratory Test Interactions

    Although interactions between benzodiazepines and commonly employed clinical laboratory tests have occasionally been reported, there is no consistent pattern for a specific drug or specific test.

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Pregnancy Exposure Registry


    There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to alprazolam extended-release tablets during pregnancy. Healthcare providers are encouraged to register patients by calling the National Pregnancy Registry for Other Psychiatric Medications at 1-866-961-2388 or visiting online at https://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/othermedications/.


    Risk Summary


    Neonates born to mothers using benzodiazepines during the later stages of pregnancy have been reported to experience symptoms of sedation and neonatal withdrawal [see Warnings and Precautions (5.4), Clinical Considerations)]. Overall available data from published observational studies of pregnant women exposed to alprazolam have not established a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes (see Data).  


    The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated risk of major birth defects and of miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.


    Clinical Considerations


    Fetal/Neonatal adverse reactions  


    Benzodiazepines cross the placenta and may produce respiratory depression and sedation in neonates. Monitor neonates exposed to benzodiazepines during pregnancy and labor for signs of sedation, respiratory depression, withdrawal, and feeding problems and manage accordingly [see Warnings and Precautions (5.4)].  


    Data 


    Human Data


    Published data from observational studies on the use of benzodiazepines during pregnancy do not report a clear association with benzodiazepines and major birth defects. Although early studies reported an increased risk of congenital malformations with diazepam and chlordiazepoxide, there was no consistent pattern noted. In addition, the majority of recent case-control and cohort studies of benzodiazepine use during pregnancy, which were adjusted for confounding exposures to alcohol, tobacco, and other medications, have not confirmed these findings. At this time, there is no clear evidence that alprazolam exposure in early pregnancy can cause major birth defects. Neonates exposed to benzodiazepines during the late third trimester of pregnancy or during labor have been reported to exhibit sedation and neonatal withdrawal symptoms.

    8.2 Lactation

    Risk Summary


    Limited data from published literature reports the presence of alprazolam in human breast milk. There are reports of sedation and withdrawal symptoms in breastfed neonates and infants exposed to alprazolam. The effects of alprazolam on lactation are unknown. Because of the potential for serious adverse reactions, including sedation and withdrawal symptoms in breastfed neonates and infants, advise patients that breastfeeding is not recommended during treatment with alprazolam extended-release tablets.

    8.4 Pediatric Use

    Safety and effectiveness of alprazolam extended-release tablets have not been established in pediatric patients.

    8.5 Geriatric Use

    Alprazolam extended-release tablets-treated geriatric patients had higher plasma concentrations of alprazolam (due to reduced clearance) compared to younger adults receiving the same doses. Therefore, dosage reduction of alprazolam extended-release tablets is recommended in geriatric patients [see Dosage and Administration (2.3) and Clinical Pharmacology (12.3)].

    8.6 Hepatic Impairment

    Patients with alcoholic liver disease exhibit a longer elimination half-life (19.7 hours), compared to healthy subjects (11.4 hours). This may be caused by decreased clearance of alprazolam in patients with alcoholic liver disease. Dosage reduction of alprazolam extended-release tablets is recommended in patients with hepatic impairment [see Dosage and Administration (2.4), Clinical Pharmacology (12.3)].

  • 9 DRUG ABUSE AND DEPENDENCE

    9.1 Controlled Substance

    Alprazolam extended-release tablets contain alprazolam, which is a Schedule IV controlled substance.

    9.2 Abuse

    Alprazolam extended-release tablets are a benzodiazepine and a CNS depressant with a potential for abuse and addiction. Abuse is the intentional, non-therapeutic use of a drug, even once, for its desirable psychological or physiological effects. Misuse is the intentional use, for therapeutic purposes, of a drug by an individual in a way other than prescribed by a health care provider or for whom it was not prescribed. Drug addiction is a cluster of behavioral, cognitive, and physiological phenomena that may include a strong desire to take the drug, difficulties in controlling drug use (e.g., continuing drug use despite harmful consequences, giving a higher priority to drug use than other activities and obligations), and possible tolerance or physical dependence.  Even taking benzodiazepines as prescribed may put patients at risk for abuse and misuse of their medication. Abuse and misuse of benzodiazepines may lead to addiction.


    Abuse and misuse of benzodiazepines often (but not always) involve the use of doses greater than the maximum recommended dosage and commonly involve concomitant use of other medications, alcohol, and/or illicit substances, which is associated with an increased frequency of serious adverse outcomes, including respiratory depression, overdose, or death. Benzodiazepines are often sought by individuals who abuse drugs and other substances, and by individuals with addictive disorders [see Warnings and Precautions (5.2)].


    The following adverse reactions have occurred with benzodiazepine abuse and/or misuse: abdominal pain, amnesia, anorexia, anxiety, aggression, ataxia, blurred vision, confusion, depression, disinhibition, disorientation, dizziness, euphoria, impaired concentration and memory, indigestion, irritability, muscle pain, slurred speech, tremors, and vertigo.


    The following severe adverse reactions have occurred with benzodiazepine abuse and/or misuse: delirium, paranoia, suicidal ideation and behavior, seizures, coma, breathing difficulty, and death. Death is more often associated with polysubstance use (especially benzodiazepines with other CNS depressants such as opioids and alcohol).

    9.3 Dependence

    Physical Dependence


    Alprazolam extended-release tablets may produce physical dependence from continued therapy. Physical dependence is a state that develops as a result of physiological adaptation in response to repeated drug use, manifested by withdrawal signs and symptoms after abrupt discontinuation or a significant dose reduction of a drug. Abrupt discontinuation or rapid dosage reduction of benzodiazepines or administration of flumazenil, a benzodiazepine antagonist, may precipitate acute withdrawal reactions, including seizures, which can be life-threatening. Patients at an increased risk of withdrawal adverse reactions after benzodiazepine discontinuation or rapid dosage reduction include those who take higher dosages (i.e., higher and/or more frequent doses) and those who have had longer durations of use [see Warnings and Precautions (5.3)].


    To reduce the risk of withdrawal reactions, use a gradual taper to discontinue alprazolam extended-release tablets or reduce the dosage [see Dosage and Administration (2.3), Warnings and Precautions (5.3)].


    Acute Withdrawal Signs and Symptoms

    Acute withdrawal signs and symptoms associated with benzodiazepines have included abnormal involuntary movements, anxiety, blurred vision, depersonalization, depression, derealization, dizziness, fatigue, gastrointestinal adverse reactions (e.g., nausea, vomiting, diarrhea, weight loss, decreased appetite), headache, hyperacusis, hypertension, irritability, insomnia, memory impairment, muscle pain and stiffness, panic attacks, photophobia, restlessness, tachycardia, and tremor. More severe acute withdrawal signs and symptoms, including life-threatening reactions, have included catatonia, convulsions, delirium tremens, depression, hallucinations, mania, psychosis, seizures, and suicidality.


    Protracted Withdrawal Syndrome


    Protracted withdrawal syndrome associated with benzodiazepines is characterized by anxiety, cognitive impairment, depression, insomnia, formication, motor symptoms (e.g., weakness, tremor, muscle twitches), paresthesia, and tinnitus that persists beyond 4 to 6 weeks after initial benzodiazepine withdrawal. Protracted withdrawal symptoms may last weeks to more than 12 months. As a result, there may be difficulty in differentiating withdrawal symptoms from potential re-emergence or continuation of symptoms for which the benzodiazepine was being used.

    Tolerance

    Tolerance to alprazolam extended-release tablets may develop from continued therapy. Tolerance is a physiological state characterized by a reduced response to a drug after repeated administration (i.e., a higher dose of a drug is required to produce the same effect that was once obtained at a lower dose). Tolerance to the therapeutic effect of alprazolam extended-release tablets may develop; however, little tolerance develops to the amnestic reactions and other cognitive impairments caused by benzodiazepines.

  • 10 OVERDOSAGE

    10.1 Clinical Experience

    Manifestations of alprazolam overdosage include somnolence, confusion, impaired coordination, diminished reflexes, and coma. Death has been reported in association with overdoses of alprazolam by itself, as it has with other benzodiazepines. In addition, fatalities have been reported in patients who have overdosed with a combination of a single benzodiazepine, including alprazolam, and alcohol; alcohol levels seen in some of these patients have been lower than those usually associated with alcohol-induced fatality.

    10.2 Management of Overdose

    If an overdose occurs, consult a Certified Poison Control Center at 1-800-222-1222 for the latest recommendations.


    As in all cases of drug overdosage, respiration, pulse rate, and blood pressure should be monitored. General supportive measures should be employed, along with immediate gastric lavage. Intravenous fluids should be administered and an adequate airway maintained. As with the management of intentional overdosing with any drug, it should be borne in mind that multiple agents may have been ingested.


    Flumazenil may be useful in situations when an overdose with a benzodiazepine is known or suspected. Prior to the administration of flumazenil, necessary measures should be instituted to secure airway, ventilation, and intravenous access. Flumazenil is intended as an adjunct to, not as a substitute for, proper management of benzodiazepine overdose. Patients treated with flumazenil should be monitored for re-sedation, respiratory depression, and other residual benzodiazepine effects for an appropriate period after treatment. The prescriber should be aware of a risk of seizure in association with flumazenil treatment, particularly in long-term benzodiazepine users and in cyclic antidepressant overdose. The complete flumazenil package insert should be consulted prior to use.

    Meets USP Dissolution Test 4.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Alprazolam is a 1,4 benzodiazepine. Alprazolam exerts its effect for the treatment of panic disorder through binding to the benzodiazepine site of gamma-aminobutyric acid-A (GABAA) receptors in the brain and enhances GABA-mediated synaptic inhibition.

    12.3 Pharmacokinetics

    The pharmacokinetics of alprazolam and two of its major active metabolites (4-hydroxyalprazolam and α-hydroxyalprazolam) are linear, and concentrations are proportional up to 10 mg alprazolam extended-release tablets given once daily.

     

    Absorption   


    Following oral administration of alprazolam extended-release tablets in the morning, peak plasma concentration of alprazolam (Cmax) occurs in about 10 hours postdose. Compared to morning dosing, alprazolam Cmax increased by 30% and the Tmax decreased by an hour following dosing at night.


    The mean absolute bioavailability of alprazolam following administration of alprazolam extended-release tablets is approximately 90%, and the relative bioavailability compared to alprazolam is about 100%. The bioavailability and pharmacokinetics of alprazolam following administration of alprazolam extended-release tablets are similar to that for alprazolam, with the exception of a slower rate of absorption.


    Effect of Food

    A high-fat meal given up to 2 hours before dosing with alprazolam extended-release tablets increased the mean Cmax by about 25%. The effect of this meal on Tmax depended on the timing of the meal, with a reduction in Tmax by about 1/3 for subjects eating immediately before dosing and an increase in Tmax by about 1/3 for subjects eating 1 hour or more after dosing. The extent of exposure (AUC) and elimination half-life (t1/2) were not affected by eating.


    Distribution  


    The apparent volume of distribution of alprazolam is similar for alprazolam extended-release tablets and alprazolam. Alprazolam is 80% bound to human serum protein, and albumin accounts for the majority of the binding.


    Elimination  


    The mean plasma elimination half-life of alprazolam following administration of alprazolam extended-release tablets ranges from 10.7 to 15.8 hours in healthy adults.


    Metabolism


    Alprazolam is extensively metabolized in humans, primarily by cytochrome P450 3A4 (CYP3A4), to two major active metabolites in the plasma: 4-hydroxyalprazolam and α-hydroxyalprazolam. The plasma circulation levels of the two active metabolites after both alprazolam extended-release tablets and alprazolam are less than 10% and 4% of the parent, respectively. The reported relative potencies in benzodiazepine receptor binding experiments and in animal models of induced seizure inhibition are 0.20 and 0.66, respectively, for 4-hydroxyalprazolam and α-hydroxyalprazolam. The low concentrations and low potencies of 4-hydroxyalprazolam and α-hydroxyalprazolam indicate that they unlikely contribute much to the effects of alprazolam. A benzophenone derived from alprazolam is also found in humans. Their half-lives appear to be similar to that of alprazolam. The pharmacokinetic parameters at steady-state for the two hydroxylated metabolites of alprazolam (4-hydroxyalprazolam and α-hydroxyalprazolam) were similar for alprazolam and alprazolam extended-release tablets, indicating that the metabolism of alprazolam is not affected by absorption rate.

    Excretion


    Alprazolam and its metabolites are excreted primarily in the urine.

    Specific Populations


    Geriatric Patients 


    The mean T1/2 of alprazolam was 16.3 hours (range: 9.0 to 26.9 hours) in healthy elderly subjects compared to 11.0 hours (range: 6.3 to -15.8 hours, n=16) in healthy adult subjects.

    Obese Patients


    The mean T1/2 of alprazolam was 21.8 hours (range: 9.9 to 40.4 hours) in a group of obese subjects.   


    Patients with Hepatic Impairment


    The mean T1/2 of alprazolam was 19.7 hours (range: 5.8 to 65.3 hours) in patients with alcoholic liver disease. 


    Racial or Ethnic Groups


    Maximal concentrations and T1/2 of alprazolam are approximately 15% and 25% higher in Asians compared to Caucasians.


    Smoking


    Alprazolam concentrations may be reduced by up to 50% in smokers compared to non-smokers.  


    Drug Interaction Studies


    In Vivo Studies


    Most of the interactions that have been documented with alprazolam are with drugs that modulate CYP3A4 activity.  


    Compounds that are inhibitors or inducers of CYP3A would be expected to increase or decrease plasma alprazolam concentrations, respectively. Drug products that have been studied in vivo, along with their effect on increasing alprazolam AUC, are as follows: ketoconazole, 3.98 fold; itraconazole, 2.66 fold; nefazodone, 1.98 fold; fluvoxamine, 1.96 fold; and erythromycin, 1.61 fold [see Contraindications (4), Warnings and Precautions (5.5), Drug Interactions (7.2)]. Other studied drugs include:


    Cimetidine: Coadministration of cimetidine increased the maximum plasma concentration of alprazolam by 82%, decreased clearance by 42%, and increased T1/2 by 16%.


    Fluoxetine: Coadministration of fluoxetine with alprazolam increased the maximum plasma concentration of alprazolam by 46%, decreased clearance by 21%, increased T1/2 by 17%, and decreased measured psychomotor performance.

    Oral Contraceptives
    : Coadministration of oral contraceptives increased the maximum plasma concentration of alprazolam by 18%, decreased clearance by 22%, and increased T1/2 by 29%.

    Carbamazepine
    : The oral clearance of alprazolam (given in a 0.8 mg single dose) was increased from 0.90±0.21 mL/min/kg to 2.13±0.54 mL/min/kg and the elimination T1/2 was shortened (from 17.1±4.9 to 7.7±1.7 hour) following administration of 300 mg per day carbamazepine for 10 days [see Drug Interactions (7.2)]. However, the carbamazepine dose used in this study was fairly low compared to the recommended doses (1000 to 1200 mg per day); the effect at usual carbamazepine doses is unknown.


    Ritonavir: Interactions involving HIV protease inhibitors (e.g., ritonavir) and alprazolam are complex and time dependent. Short-term low doses of ritonavir (4 doses of 200 mg) increased mean AUC of alprazolam by about 2.5-fold, and did not significantly affect Cmax of alprazolam. The elimination T1/2 was prolonged (30 hours versus 13 hours). However, upon extended exposure to ritonavir (500 mg, twice daily for 10 days), CYP3A induction offset this inhibition. Alprazolam AUC and Cmax was reduced by 12% and 16%, respectively, in the presence of ritonavir. The elimination T1/2 of alprazolam was not significantly changed [see Warnings and Precautions (5.5)].


    Sertraline: A single dose of alprazolam 1 mg and steady state dose of sertraline (50 to 150 mg per day) did not reveal any clinically significant changes in the pharmacokinetics of alprazolam.


    Imipramine and Desipramine: The steady state plasma concentrations of imipramine and desipramine have been reported to be increased an average of 31% and 20%, respectively, by the concomitant administration of alprazolam in doses up to 4 mg per day. 


    Warfarin: Alprazolam did not affect the prothrombin or plasma warfarin levels in male volunteers administered sodium warfarin orally.

    In Vitro Studies

    Data from in vitro studies of alprazolam suggest a possible drug interaction of alprazolam with paroxetine. The ability of alprazolam to induce human hepatic enzyme systems has not yet been determined.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    Carcinogenesis


    No evidence of carcinogenic potential was observed in rats or mice administered alprazolam for 2 years at doses up to 30 and 10 mg/kg/day, respectively. These doses are 29 times and 4.8 times the maximum recommended human dose of 10 mg/day based on mg/m2 body surface area, respectively.


    Mutagenesis


    Alprazolam was negative in the in vitro Ames bacterial reverse mutation assay and DNA Damage/Alkaline Elution Assay and in vivo rat micronucleus genetic toxicology assays.


    Impairment of Fertility


    Alprazolam produced no impairment of fertility in rats at doses up to 5 mg/kg per day, which is approximately 5 times the maximum recommended human dose of 10 mg per day based on mg/m2 body surface area.

    13.2 Animal Toxicology and/or Pharmacology

    When rats were treated with alprazolam at oral doses of 3 mg/kg, 10 mg/kg, and 30 mg/kg per day (3 to 29 times the maximum recommended human dose based on mg/m2 body surface area) for 2 years, a tendency for a dose related increase in the number of cataracts was observed in females and a tendency for a dose related increase in corneal vascularization was observed in males. These lesions did not appear until after 11 months of treatment.

  • 14 CLINICAL STUDIES

    The efficacy of alprazolam extended-release tablets in the treatment of panic disorder in adults was established in two 6-week, flexible-dose, placebo-controlled studies in adult patients meeting DSM-III criteria for panic disorder. In these studies, patients were treated with alprazolam extended-release tablets in a dose range of 1 mg to 10 mg once per day. The effectiveness of alprazolam extended-release tablets was assessed on the basis of changes in various measures of panic attack frequency, on various measures of the Clinical Global Impression, and on the Overall Phobia Scale. In all, there were 7 primary efficacy measures in these studies, and alprazolam extended-release tablets was superior to placebo on all 7 outcomes in both studies. The mean dose of alprazolam extended-release tablets at the last treatment visit was 4.2 mg per day in the first study and 4.6 mg per day in the second.


    In addition, there were two 8-week, fixed-dose, placebo-controlled studies of alprazolam extended-release tablets in adult patients with panic disorder, involving fixed alprazolam extended-release tablets doses of 4 mg and 6 mg once per day that did not show a benefit for either dose of alprazolam extended-release tablets.


    Analyses of the relationship between treatment outcome and gender did not suggest any differential responsiveness on the basis of gender.

  • 17 PATIENT COUNSELING INFORMATION

    Advise the patient to read the FDA-approved patient labeling (Medication Guide).


    Risks from Concomitant Use with Opioids


    Advise both patients and caregivers about the risks of potentially fatal respiratory depression and sedation when alprazolam extended-release tablets are used with opioids and not to use such drugs concomitantly unless supervised by a healthcare provider. Advise patients not to drive or operate heavy machinery until the effects of concomitant use with the opioid have been determined [see Warnings and Precautions (5.1), Drug Interactions (7.1)].

    Abuse, Misuse, and Addiction


    Inform patients that the use of alprazolam extended-release tablets, even at recommended dosages, exposes users to risks of abuse, misuse, and addiction, which can lead to overdose and death, especially when used in combination with other medications (e.g., opioid analgesics), alcohol, and/or illicit substances. Inform patients about the signs and symptoms of benzodiazepine abuse, misuse, and addiction; to seek medical help if they develop these signs and/or symptoms; and on the proper disposal of unused drug [see Warnings and Precautions (5.2), Drug Abuse and Dependence (9.2)].


    Withdrawal Reactions


    Inform patients that the continued use of alprazolam extended-release tablets may lead to clinically significant physical dependence and that abrupt discontinuation or rapid dosage reduction of alprazolam extended-release tablets may precipitate acute withdrawal reactions, which can be life-threatening. Inform patients that in some cases, patients taking benzodiazepines have developed a protracted withdrawal syndrome with withdrawal symptoms lasting weeks to more than 12 months. Instruct patients that discontinuation or dosage reduction of alprazolam extended-release tablets may require a slow taper [see Warnings and Precautions (5.3), Drug Abuse and Dependence (9.3)].


    Effects on Driving and Operating Machinery


    Advise patients not to drive a motor vehicle or operate heavy machinery while taking alprazolam extended-release tablets due to its CNS depressant effects. Also advise patients to avoid use of alcohol or other CNS depressants while taking alprazolam extended-release tablets [see Warnings and Precautions (5.3)].


    Patients with Depression

    Concomitant Medications


    Advise patients to inform their healthcare provider of all medicines they take, including prescription and nonprescription medications, vitamins and herbal supplements [see Drug Interactions (7)].

    Pregnancy


    Benzodiazepines cross the placenta and may produce respiratory depression and sedation in neonates. Advise mothers using alprazolam extended-release tablets to monitor neonates for signs of sedation, respiratory depression, withdrawal symptoms, and feeding problems. Instruct patients to inform their healthcare provider if they are pregnant or intend to become pregnant during treatment with alprazolam extended-release tablets [see Warnings and Precautions (5.4)]. Advise patients that there is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to alprazolam extended-release tablets during pregnancy [see Use in Specific Populations (8.1)].
