  • 1 INDICATIONS AND USAGE

    1.1 Pneumonia

    Cefepime for injection is indicated in the treatment of pneumonia (moderate to severe) caused by susceptible strains of Streptococcus pneumoniae, including cases associated with concurrent bacteremia, Pseudomonas aeruginosa, Klebsiella pneumoniae, or Enterobacter species.

    1.2 Empiric Therapy for Febrile Neutropenic Patients

    Cefepime for injection as monotherapy is indicated for empiric treatment of febrile neutropenic patients. In patients at high risk for severe infection (including patients with a history of recent bone marrow transplantation, with hypotension at presentation, with an underlying hematologic malignancy, or with severe or prolonged neutropenia), antimicrobial monotherapy may not be appropriate. Insufficient data exist to support the efficacy of cefepime monotherapy in such patients [see Clinical Studies (14.1)].

    1.3 Uncomplicated and Complicated Urinary Tract Infections (including pyelonephritis)

    Cefepime for injection is indicated in the treatment of uncomplicated and complicated urinary tract infections (including pyelonephritis) caused by susceptible isolates of Escherichia coli or Klebsiella pneumoniae, when the infection is severe, or caused by Escherichia coli, Klebsiella pneumoniae, or Proteus mirabilis, when the infection is mild to moderate, including cases associated with concurrent bacteremia with these bacteria.

    1.4 Uncomplicated Skin and Skin Structure Infections

    Cefepime for injection is indicated in the treatment of uncomplicated skin and skin structure infections caused by Staphylococcus aureus (methicillin-susceptible isolates only) or Streptococcus pyogenes.

    1.5 Complicated Intra-abdominal Infections (used in combination with metronidazole)

    Cefepime for injection is indicated in the treatment of complicated intra-abdominal infections (used in combination with metronidazole) in adults caused by susceptible isolates of Escherichia coli, viridans group streptococci, Pseudomonas aeruginosa, Klebsiella pneumoniae, Enterobacter species, or Bacteroides fragilis  [see Clinical Studies (14.2)].

    1.6 Usage

    To reduce the development of drug-resistant bacteria and maintain the effectiveness of cefepime for injection and other antibacterial drugs, cefepime for injection should be used only to treat infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

    *or until resolution of neutropenia. In patients whose fever resolves but who remain neutropenic for more than 7 days, the need for continued antimicrobial therapy should be re-evaluated frequently.

    **Intramuscular route of administration is indicated only for mild to moderate, uncomplicated or complicated UTIs due to E. coli.

    §For P. aeruginosa, use 2 g IV every 8 hours.

    2.2 Pediatric Patients (2 months up to 16 years)

    The maximum dose for pediatric patients should not exceed the recommended adult dose.

    The usual recommended dosage in pediatric patients up to 40 kg in weight for durations as given above for adults is:

    50 mg per kg per dose, administered every 12 hours for uncomplicated and complicated urinary tract infections (including pyelonephritis), uncomplicated skin and skin structure infections, and pneumonia (see below).
    For moderate to severe pneumonia due to P. aeruginosa give 50 mg per kg per dose, every 8 hours.
    50 mg per kg per dose, every 8 hours for febrile neutropenic patients.

    2.3 Dosage Adjustments in Patients with Renal Impairment

    Adult Patients

    Adjust the dose of cefepime for injection in patients with creatinine clearance less than or equal to 60 mL/min to compensate for the slower rate of renal elimination. In these patients, the recommended initial dose of cefepime for injection should be the same as in patients with CrCL greater than 60 mL/min except in patients undergoing hemodialysis. The recommended doses of cefepime for injection in patients with renal impairment are presented in Table 2.

    When only serum creatinine is available, the following formula (Cockcroft and Gault equation)4 may be used to estimate creatinine clearance. The serum creatinine should represent a steady state of renal function:

    Males: Creatinine Clearance (mL/min) =         Weight (kg) x (140 – age)

                                                                         72 x serum creatinine (mg/dL)

    Females: 0.85 x above value

    *On hemodialysis days, cefepime should be administered following hemodialysis. Whenever possible, cefepime should be administered at the same time each day.

    In patients undergoing Continuous Ambulatory Peritoneal Dialysis (CAPD), cefepime for injection may be administered at the recommended doses at a dosage interval of every 48 hours (see Table 2).

    In patients undergoing hemodialysis, approximately 68% of the total amount of cefepime present in the body at the start of dialysis will be removed during a 3-hour dialysis period. The dosage of cefepime for injection for hemodialysis patients is 1 g on Day 1 followed by 500 mg every 24 hours for the treatment of all infections except febrile neutropenia, which is 1 g every 24 hours.

    Cefepime for injection should be administered at the same time each day and following the completion of hemodialysis on hemodialysis days (see Table 2).

    Pediatric Patients

    Data in pediatric patients with impaired renal function are not available; however, since cefepime pharmacokinetics are similar in adults and pediatric patients [see Clinical Pharmacology (12.3)], changes in the dosing regimen proportional to those in adults (see Tables 1 and 2) are recommended for pediatric patients.

    2.4 Preparation of Cefepime for Injection for Intravenous Infusion

    Vials

    Constitute the 1 gram, or 2 gram vial, of cefepime for injection with one of the following diluents:
    Sterile Water for Injection
    0.9% Sodium Chloride Injection
    5% Dextrose Injection
    0.5% or 1% Lidocaine Hydrochloride Injection
    Sterile Bacteriostatic Water for Injection with Parabens or Benzyl Alcohol
    Dilute reconstituted solution with one of the following compatible infusion solutions prior to intravenous infusion (Refer to Table 3 below for the amount of diluent to be added to each vial):

    Close
  • 4 CONTRAINDICATIONS

    Cefepime for injection is contraindicated in patients who have shown immediate hypersensitivity reactions to cefepime or the cephalosporin class of antibiotics, penicillins or other beta-lactam antibiotics.

    Close
  • 5 WARNINGS AND PRECAUTIONS

    5.1 Hypersensitivity Reactions

    Before therapy with cefepime for injection is instituted, careful inquiry should be made to determine whether the patient has had previous immediate hypersensitivity reactions to cefepime, cephalosporins, penicillins, or other beta-lactams. Exercise caution if this product is to be given to penicillin-sensitive patients because cross-hypersensitivity among beta-lactam antibacterial drugs has been clearly documented and may occur in up to 10% of patients with a history of penicillin allergy. If an allergic reaction to cefepime for injection occurs, discontinue the drug and institute appropriate supportive measures.

    5.2 Neurotoxicity

    Serious adverse reactions have been reported including life-threatening or fatal occurrences of the following: encephalopathy (disturbance of consciousness including confusion, hallucinations, stupor, and coma), aphasia, myoclonus, seizures, and nonconvulsive status epilepticus [see Adverse Reactions (6.2)]. Most cases occurred in patients with renal impairment who did not receive appropriate dosage adjustment. However, some cases of neurotoxicity occurred in patients receiving a dosage adjustment appropriate for their degree of renal impairment. In the majority of cases, symptoms of neurotoxicity were reversible and resolved after discontinuation of cefepime and/or after hemodialysis. If neurotoxicity associated with cefepime therapy occurs, discontinue cefepime and institute appropriate supportive measures.

    5.3 Clostridium difficile Associated Diarrhea

    Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including cefepime for injection, and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile.

    C. difficile produces toxins A and B, which contribute to the development of CDAD. Hypertoxin-producing strains of C. difficile cause increased morbidity and mortality, as these infections can be refractory to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibacterial drug use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents.

    If CDAD is suspected or confirmed, ongoing antibacterial drug use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment of C. difficile, and surgical evaluation should be instituted as clinically indicated.

    5.4 Development of Drug-Resistant Bacteria

    Prescribing cefepime for injection in the absence of a proven or strongly suspected bacterial infection is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria.

    As with other antimicrobials, prolonged use of cefepime for injection may result in overgrowth of nonsusceptible microorganisms. Repeated evaluation of the patient’s condition is essential. Should superinfection occur during therapy, appropriate measures should be taken.

    5.5 Drug/Laboratory Test Interactions

    Urinary Glucose

    The administration of cefepime may result in a false-positive reaction for glucose in the urine when using some methods (e.g. Clinitest™ tablets) [see Drug Interactions (7.1)].

    Coombs’ Tests

    Positive direct Coombs’ tests have been reported during treatment with cefepime for injection. In patients who develop hemolytic anemia, discontinue the drug and institute appropriate therapy. Positive Coombs’ test may be observed in newborns whose mothers have received cephalosporin antibiotics before parturition.

    Prothrombin Time

    Many cephalosporins, including cefepime, have been associated with a fall in prothrombin activity. Those at risk include patients with renal or hepatic impairment, or poor nutritional state, as well as patients receiving a protracted course of antimicrobial therapy. Prothrombin time should be monitored in patients at risk, and exogenous vitamin K administered as indicated.

    6.1 Clinical Trials Experience

    Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in 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.

    In clinical trials using multiple doses of cefepime, 4,137 patients were treated with the recommended dosages of cefepime (500 mg to 2 g intravenous every 12 hours). There were no deaths or permanent disabilities thought related to drug toxicity. Sixty-four (1.5%) patients discontinued medication due to adverse reactions. Thirty-three (51%) of these 64 patients who discontinued therapy did so because of rash. The percentage of cefepime-treated patients who discontinued study drug because of drug-related adverse reactions was similar at daily doses of 500 mg, 1 g, and 2 g every 12 hours (0.8%, 1.1%, and 2%, respectively). However, the incidence of discontinuation due to rash increased with the higher recommended doses.

    The following adverse reactions (Table 5) were identified in clinical trials conducted in North America (n=3,125 cefepime-treated patients).

    Table 5: Adverse Reactions in Cefepime Multiple-Dose Dosing Regimens Clinical Trials in North America

    Incidence equal to or greater than 1%

    Local adverse reactions (3%), including phlebitis (1.3%), pain and/or inflammation (0.6%)*; rash (1.1%)

    Incidence less than 1% but greater than 0.1%

    Colitis (including pseudomembranous colitis), diarrhea, erythema, fever, headache, nausea, oral moniliasis, pruritus, urticaria, vaginitis, vomiting, anemia


    At the higher dose of 2 g every 8 hours, the incidence of adverse reactions was higher among the 795 patients who received this dose of cefepime. They consisted of rash (4%), diarrhea (3%), nausea (2%), vomiting (1%), pruritus (1%), fever (1%), and headache (1%).

    The following (Table 6) adverse laboratory changes, with cefepime, were seen during clinical trials conducted in North America.

    Table 6: Adverse Laboratory Changes in Cefepime Multiple-Dose Dosing Regimens Clinical Trials in North America

    Incidence equal to or greater than 1%

    Positive Coombs’ test (without hemolysis) (16.2%); decreased phosphorus (2.8%); increased Alanine Transaminase (ALT) (2.8%), Aspartate Transaminase (AST) (2.4%), eosinophils (1.7%); abnormal PTT (1.6%), Prothrombin Time (PT) (1.4%)

    Incidence less than 1% but greater than 0.1%

    Increased alkaline phosphatase, Blood Urea Nitrogen (BUN), calcium, creatinine, phosphorus, potassium, total bilirubin; decreased calcium*, hematocrit, neutrophils, platelets, White Blood Cells (WBC)

    * Hypocalcemia was more common among elderly patients. Clinical consequences from changes in either calcium or phosphorus were not reported.

    A similar safety profile was seen in clinical trials of pediatric patients.

    6.2 Postmarketing Experience

    The following adverse reactions have been identified during post-approval use of cefepime for injection. 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.

    In addition to the adverse reactions reported during the North American clinical trials with cefepime, the following adverse reactions have been reported during worldwide postmarketing experience. Encephalopathy (disturbance of consciousness including confusion, hallucinations, stupor, and coma), aphasia, myoclonus, seizures, and nonconvulsive status epilepticus have been reported. [see Warnings and Precautions (5.2)]

    Anaphylaxis including anaphylactic shock, transient leukopenia, neutropenia, agranulocytosis and thrombocytopenia, have been reported.

    6.3 Cephalosporin-Class Adverse Reactions

    In addition to the adverse reactions listed above that have been observed in patients treated with cefepime, the following adverse reactions and altered laboratory tests have been reported for cephalosporin-class antibacterial drugs:

    Stevens-Johnson syndrome, erythema multiforme, toxic epidermal necrolysis, renal dysfunction, toxic nephropathy, aplastic anemia, hemolytic anemia, hemorrhage, hepatic dysfunction including cholestasis, and pancytopenia.

  • 7 DRUG INTERACTIONS

    7.1 Drug/Laboratory Test Interactions

    The administration of cefepime may result in a false-positive reaction for glucose in the urine with certain methods. It is recommended that glucose tests based on enzymatic glucose oxidase reactions be used.

    7.2 Aminoglycosides

    Monitor renal function if aminoglycosides are to be administered with cefepime for injection because of the increased potential of nephrotoxicity and ototoxicity of aminoglycoside antibacterial drugs.

    7.3 Diuretics

    Nephrotoxicity has been reported following concomitant administration of other cephalosporins with potent diuretics such as furosemide. Monitor renal function when cefepime is concomitantly administered with potent diuretics.

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Pregnancy Category B
    There are no adequate and well-controlled studies of cefepime use in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.

    Cefepime was not teratogenic or embryocidal when administered during the period of organogenesis to rats at doses up to 1,000 mg/kg/day (1.6 times the recommended maximum human dose calculated on a body surface area basis) or to mice at doses up to 1,200 mg/kg (approximately equal to the recommended maximum human dose calculated on a body surface area basis) or to rabbits at a dose level of 100 mg/kg (0.3 times the recommended maximum human dose calculated on a body surface area basis).

    8.2 Labor and Delivery

    Cefepime has not been studied for use during labor and delivery. Treatment should only be given if clearly indicated.

    8.3 Nursing Mothers

    Cefepime is excreted in human breast milk. Caution should be exercised when cefepime is administered to a nursing woman [see Clinical Pharmacology (12.3)].

    8.4 Pediatric Use

    The safety and effectiveness of cefepime in the treatment of uncomplicated and complicated urinary tract infections (including pyelonephritis), uncomplicated skin and skin structure infections, pneumonia, and as empiric therapy for febrile neutropenic patients have been established in the age groups 2 months up to 16 years. Use of cefepime for injection in these age groups is supported by evidence from adequate and well-controlled studies of cefepime in adults with additional pharmacokinetic and safety data from pediatric trials [see Clinical Pharmacology (12.3)].

    Safety and effectiveness in pediatric patients below the age of 2 months have not been established. There are insufficient clinical data to support the use of cefepime for injection in pediatric patients for the treatment of serious infections in the pediatric population where the suspected or proven pathogen is H. influenzae type b. In those patients in whom meningeal seeding from a distant infection site or in whom meningitis is suspected or documented, an alternate agent with demonstrated clinical efficacy in this setting should be used.

    8.5 Geriatric Use

    Of the more than 6,400 adults treated with cefepime for injection in clinical studies, 35% were 65 years or older while 16% were 75 years or older. When geriatric patients received the usual recommended adult dose, clinical efficacy and safety were comparable to clinical efficacy and safety in non-geriatric adult patients.

    Serious adverse events have occurred in geriatric patients with renal insufficiency given unadjusted doses of cefepime, including life-threatening or fatal occurrences of the following: encephalopathy, myoclonus, and seizures [see Warnings and Precautions (5.2), Adverse Reactions (6.2)].

    This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and renal function should be monitored [see Clinical Pharmacology (12.3), Warnings and Precautions (5.2), Dosage and Administration (2.3)].

    8.6 Renal Impairment

    Adjust the dose of cefepime for injection in patients with creatinine clearance less than or equal to 60 mL/min to compensate for the slower rate of renal elimination [see Dosage Adjustments in Patients with Renal Impairment (2.3)].

    Close
  • 10 OVERDOSAGE

    Patients who receive an overdose should be carefully observed and given supportive treatment. In the presence of renal insufficiency, hemodialysis, not peritoneal dialysis, is recommended to aid in the removal of cefepime from the body. Symptoms of overdose include encephalopathy (disturbance of consciousness including confusion, hallucinations, stupor, and coma), myoclonus, seizures, neuromuscular excitability, and nonconvulsive status epilepticus [see Warnings and Precautions (5.2), Adverse Reactions (6.2), Dosage and Administration (2.3)].

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Cefepime is a cephalosporin antibacterial drug [see Microbiology (12.4)].

    12.2 Pharmacodynamics

    Similar to other beta-lactam antimicrobial agents, the time that the unbound plasma concentration of cefepime exceeds the MIC of the infecting organism has been shown to best correlate with efficacy in animal models of infection. However, the pharmacokinetic/pharmacodynamics relationship for cefepime has not been evaluated in patients.

    12.3 Pharmacokinetics

    Pharmacokinetic parameters for cefepime in healthy adult male volunteers (n=9) following single 30‑minute infusions (IV) of cefepime 500 mg, 1 g, and 2 g are summarized in Table 7. Elimination of cefepime is principally via renal excretion with an average (±SD) half-life of 2 (±0.3) hours and total body clearance of 120 (±8) mL/min in healthy volunteers. Cefepime pharmacokinetics are linear over the range 250 mg to 2 g. There is no evidence of accumulation in healthy adult male volunteers (n=7) receiving clinically relevant doses for a period of 9 days.

    Distribution

    The average steady-state volume of distribution of cefepime is 18 (±2) L. The serum protein binding of cefepime is approximately 20% and is independent of its concentration in serum.

    Cefepime is excreted in human milk at a concentration of 0.5 mcg/mL. A nursing infant consuming approximately 1000 mL of human milk per day would receive approximately 0.5 mg of cefepime per day [see Use in Specific Populations (8.3)].

    Concentrations of cefepime achieved in specific tissues and body fluids are listed in Table 9.

    Data suggest that cefepime does cross the inflamed blood-brain barrier. The clinical relevance of these data is uncertain at this time.

    Metabolism and Excretion

    Cefepime is metabolized to N-methylpyrrolidine (NMP) which is rapidly converted to the N-oxide (NMP-N-oxide). Urinary recovery of unchanged cefepime accounts for approximately 85% of the administered dose. Less than 1% of the administered dose is recovered from urine as NMP, 6.8% as NMP-N-oxide, and 2.5% as an epimer of cefepime. Because renal excretion is a significant pathway of elimination, patients with renal dysfunction and patients undergoing hemodialysis require dosage adjustment [see Dosage and Administration (2.3)].

    Specific Populations

    Patients with Renal impairment

    Cefepime pharmacokinetics have been investigated in patients with various degrees of renal impairment (n=30). The average half-life in patients requiring hemodialysis was 13.5 (±2.7) hours and in patients requiring continuous peritoneal dialysis was 19 (±2) hours. Cefepime total body clearance decreased proportionally with creatinine clearance in patients with abnormal renal function, which serves as the basis for dosage adjustment recommendations in this group of patients [see Dosage and Administration (2.3)].

    Patients with Hepatic impairment

    The pharmacokinetics of cefepime were unaltered in patients with hepatic impairment who received a single 1 g dose (n=11).

    Geriatric patients

    Cefepime pharmacokinetics have been investigated in elderly (65 years of age and older) men (n=12) and women (n=12) whose mean (SD) creatinine clearance was 74 (±15) mL/min. There appeared to be a decrease in cefepime total body clearance as a function of creatinine clearance. Therefore, dosage administration of cefepime in the elderly should be adjusted as appropriate if the patient’s creatinine clearance is 60 mL/min or less [see Dosage and Administration (2.3)].

    Pediatric patients

    Cefepime pharmacokinetics have been evaluated in pediatric patients from 2 months to 11 years of age following single and multiple doses on every 8 hours (n=29) and every 12 hours (n=13) schedules. Following a single intravenous dose, total body clearance and the steady-state volume of distribution averaged 3.3 (±1) mL/min/kg and 0.3 (±0.1) L/kg, respectively. The urinary recovery of unchanged cefepime was 60.4 (±30.4)% of the administered dose, and the average renal clearance was 2 (±1.1) mL/min/kg. There were no significant effects of age or gender (25 male vs. 17 female) on total body clearance or volume of distribution, corrected for body weight. No accumulation was seen when cefepime was given at 50 mg per kg every 12 hours (n=13), while Cmax, AUC, and t½ were increased about 15% at steady state after 50 mg per kg every 8 hours. The exposure to cefepime following a 50 mg per kg intravenous dose in a pediatric patient is comparable to that in an adult treated with a 2 g intravenous dose. The absolute bioavailability of cefepime after an intramuscular dose of 50 mg per kg was 82.3 (±15)% in eight patients.

    12.4 Microbiology

    Mechanism of Action

    Cefepime is a bactericidal drug that acts by inhibition of bacterial cell wall synthesis. Cefepime has a broad spectrum of in vitro activity that encompasses a wide range of Gram-positive and Gram-negative bacteria. Within bacterial cells, the molecular targets of cefepime are the penicillin binding proteins (PBP).

    Antimicrobial Activity

    Cefepime has been shown to be active against most isolates of the following microorganisms, both in vitro and in clinical infections as described in the Indications and Usage section (1).

    Gram-negative Bacteria

    Enterobacter spp.

    Escherichia coli

    Klebsiella pneumoniae

    Proteus mirabilis

    Pseudomonas aeruginosa

    Gram-positive Bacteria

    Staphylococcus aureus (methicillin-susceptible isolates only)

    Streptococcus pneumoniae

    Streptococcus pyogenes

    Viridans group streptococci

    The following in vitro data are available, but their clinical significance is unknown. At least 90 percent of the following bacteria exhibit an in vitro minimum inhibitory concentration (MIC) less than or equal to the susceptible breakpoint for cefepime against isolates of similar genus or organism group. However, the efficacy of cefepime in treating clinical infections due to these bacteria has not been established in adequate and well-controlled clinical trials.

    Gram-positive Bacteria

    Staphylococcus epidermidis (methicillin-susceptible isolates only)

    Staphylococcus saprophyticus

    Streptococcus agalactiae

    NOTE: Most isolates of enterococci, e.g., Enterococcus faecalis, and methicillin-resistant staphylococci are resistant to cefepime.

    Gram-negative Bacteria

    Acinetobacter calcoaceticus subsp. lwoffii

    Citrobacter diversus

    Citrobacter freundii

    Enterobacter agglomerans

    Haemophilus influenzae

    Hafnia alvei

    Klebsiella oxytoca

    Moraxella catarrhalis

    Morganella morganii

    Proteus vulgaris

    Providencia rettgeri

    Providencia stuartii

    Serratia marcescens

    NOTE: Cefepime is inactive against many isolates of Stenotrophomonas maltophilia.

    Susceptibility Test Methods

    When available, the clinical microbiology laboratory should provide cumulative reports of in vitro susceptibility test results for antimicrobial drugs used in local hospitals and practice areas to the physician as periodic reports that describe the susceptibility profile of nosocomial and community-acquired pathogens. These reports should aid the physician in selecting an antibacterial drug for treatment.

    Dilution techniques

    Quantitative methods are used to determine antimicrobial minimum inhibitory concentrations (MICs). These MICs provide estimates of the susceptibility of bacteria to antimicrobial compounds. The MICs should be determined using a standardized test method1,2  (broth and/or agar). The MIC should be interpreted according to criteria provided in Table 10.

    Diffusion techniques

    Quantitative methods that require measurement of zone diameters can also provide reproducible estimates of the susceptibility of bacteria to antimicrobial compounds.  The zone size should be determined using a standardized test method.2,3 This procedure uses paper discs impregnated with 30 mcg cefepime to test the susceptibility of microorganisms to cefepime. The disk diffusion interpretive criteria are provided in Table 10.

    ¥For patients with renal impairment see Table 2 in Dosage and Administration.

    *For isolates of Enterobacteriaceae with intermediate susceptibility, use a dose of 2 g every 8 hours in patients with normal renal function.

    §For P. aeruginosa, use 2 g IV every 8 hours in patients with normal renal function.

    bFor non-meningitis isolates, a penicillin MIC of < 0.06 mcg/mL (or oxacillin zone > 20 mm) can predict susceptibility to cefepime.

    Susceptibility of staphylococci to cefepime may be deduced from testing only penicillin and either cefoxitin or oxacillin.

    A report of Susceptible (S) indicates that the antimicrobial drug is likely to inhibit growth of the pathogen if the antimicrobial drug reaches the concentration usually achievable at the site of infection. A report of Intermediate (I) indicates that the result should be considered equivocal, and, if the microorganism is not fully susceptible to alternative, clinically feasible drugs, the test should be repeated. This category implies possible clinical applicability in body sites where the drug is physiologically concentrated or in situations where a high dosage of the drug can be used.  This category also provides a buffer zone that prevents small uncontrolled technical factors from causing major discrepancies in interpretation. A report of Resistant (R) indicates that the antimicrobial drug is not likely to inhibit growth of the pathogen if the antimicrobial drug reaches the concentration usually achievable at the infection site; other therapy should be selected.

    Quality Control

    Standardized susceptibility test procedures require the use of laboratory controls to monitor and ensure the accuracy and precision of supplies and reagents used in the assay, and the techniques of the individual performing the test.1,2,3 Standard cefepime powder should provide the following range of MIC values noted in Table 11. For the diffusion technique using the 30 mcg disc, the criteria in Table 11 should be achieved.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    No animal carcinogenicity studies have been conducted with cefepime. In chromosomal aberration studies, cefepime was positive for clastogenicity in primary human lymphocytes, but negative in Chinese hamster ovary cells. In other in vitro assays (bacterial and mammalian cell mutation, DNA repair in primary rat hepatocytes, and sister chromatid exchange in human lymphocytes), cefepime was negative for genotoxic effects. Moreover, in vivo assessments of cefepime in mice (2 chromosomal aberration and 2 micronucleus studies) were negative for clastogenicity. No untoward effects on fertility were observed in rats when cefepime was administered subcutaneously at doses up to 1,000 mg/kg/day (1.6 times the recommended maximum human dose calculated on a body surface area basis).

    Insufficient data exist to support the efficacy of cefepime monotherapy in patients at high risk for severe infection (including patients with a history of recent bone marrow transplantation, with hypotension at presentation, with an underlying hematologic malignancy, or with severe or prolonged neutropenia). No data are available in patients with septic shock.

    14.2 Complicated Intra-abdominal Infections

    Patients hospitalized with complicated intra-abdominal infections participated in a randomized, double-blind, multicenter trial comparing the combination of cefepime (2 g every 12 hours) plus intravenous metronidazole (500 mg every 6 hours) versus imipenem/cilastatin (500 mg every 6 hours) for a maximum duration of 14 days of therapy. The study was designed to demonstrate equivalence of the two therapies. The primary analyses were conducted on the population consisting of those with a surgically confirmed complicated infection, at least one pathogen isolated pretreatment, at least 5 days of treatment, and a 4 to 6 week follow-up assessment for cured patients. Subjects in the imipenem/cilastatin arm had higher APACHE II scores at baseline.  The treatment groups were otherwise  generally comparable with regard to their pretreatment characteristics. The overall clinical cure rate among the primary analysis patients was 81% (51 cured/63 evaluable patients) in the cefepime plus metronidazole group and 66% (62/94) in the imipenem/cilastatin group. The observed differences in efficacy may have been due to a greater proportion of patients with high APACHE II scores in the imipenem/cilastatin group.

  • 17 PATIENT COUNSELING INFORMATION

    Counsel patients that antibacterial drugs including cefepime for injection should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When cefepime for injection is prescribed to treat a bacterial infection, tell patients that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by cefepime for injection or other antibacterial drugs in the future.
    Diarrhea is a common problem caused by antibacterial drugs, which usually ends when the antibiotic is discontinued. Inform patient that they may develop watery and bloody stools (with or without stomach cramps and fever) during treatment and as late as two or more months after having taken the last dose of the antibiotic. Inform patients that they should contact their physician as soon as possible if this occurs.
    Advise  patients of  neurological adverse events that  could  occur  with  cefepime for injection  use.  Instruct patients or their caregivers to inform their healthcare provider at once of any neurological signs and symptoms, including encephalopathy (disturbance of consciousness including confusion, hallucinations, stupor, and coma), aphasia (disturbance of speaking and understanding spoken and written language), myoclonus, seizures and nonconvulsive status epilepticus, for immediate treatment, dosage adjustment, or discontinuation of cefepime for injection.
