Label: ALBUTEROL SULFATE INHALATION SOLUTION- albuterol sulfate solution

Albuterol sulfate inhalation solution is a sterile, clear, colorless solution of the sulfate salt of racemic albuterol, albuterol sulfate. Albuterol sulfate is a relatively selective beta 2- adrenergic bronchodilator (see CLINICAL PHARMACOLOGY). The chemical name for albuterol sulfate is α 1[(tert-butylamino) methyl]-4-hydroxy-m-xylene-α, α’-diol sulfate (2:1) (salt), and its established chemical structure is as follows:

The molecular weight of albuterol sulfate is 576.7 and the empirical formula is (C 13H 21NO 3) 2• H 2SO 4. Albuterol sulfate is a white crystalline powder, soluble in water and slightly soluble in ethanol. The World Health Organization recommended name for albuterol is salbutamol.

Albuterol Sulfate Inhalation Solution is supplied in two strengths in unit dose vials. Each unit dose vial contains either 0.63 mg of albuterol equivalent to 0.75 mg of albuterol sulfate or 1.25 mg of albuterol equivalent to 1.5 mg of albuterol sulfate with sodium chloride, edetate disodium (EDTA), and sulfuric acid in a 3-mL isotonic, sterile, aqueous solution. Sodium chloride is added to adjust isotonicity of the solution, EDTA is added as a stabilizer for the active pharmaceutical ingredient, and sulfuric acid is added to adjust pH of the solution to 3.5 (see HOW SUPPLIED).

Albuterol Sulfate Inhalation Solution does not require dilution prior to administration by nebulization. For Albuterol Sulfate Inhalation Solution, like all other nebulized treatments, the amount delivered to the lungs will depend on patient factors, the jet nebulizer utilized, and compressor performance. Using the Pari LC Plus™ nebulizer (with face mask or mouthpiece) connected to a Pari PRONEB™ compressor, under in vitro conditions, the mean delivered dose from the mouth piece (% nominal dose) was approximately 43% of albuterol (1.25 mg strength) and 39% of albuterol (0.63 mg strength) at a mean flow rate of 3.6 L/min. The mean nebulization time was 15 minutes or less. Albuterol Sulfate Inhalation Solution should be administered from a jet nebulizer at an adequate flow rate, via a mouthpiece or face mask (see DOSAGE AND ADMINISTRATION).

The prime action of beta-adrenergic drugs is to stimulate adenyl cyclase, the enzyme which catalyzes the formation of cyclic-3’,5’-adenosine monophosphate (cyclic AMP) from adenosine triphosphate (ATP). The cyclic AMP thus formed mediates the cellular responses. In vitrostudies and in vivopharmacologic studies have demonstrated that albuterol has a preferential effect on beta 2-adrenergic receptors compared with isoproterenol. While it is recognized that beta 2-adrenergic receptors are the predominant receptors in bronchial smooth muscle, recent data indicate that 10% to 50% of the beta-receptors in the human heart may be beta 2-receptors. The precise function of these receptors, however, is not yet established. Controlled clinical studies and other clinical experience have shown that inhaled albuterol, like other beta-adrenergic agonist drugs, can produce a significant cardiovascular effect in some patients, as measured by pulse rate, blood pressure, symptoms, and/or electrocardiographic changes. Albuterol is longer acting than isoproterenol in most patients by any route of administration because it is not a substrate for the cellular uptake processes for catecholamines nor for catechol-O-methyl transferase.

Albuterol Sulfate Inhalation Solution is indicated for the relief of bronchospasm in patients 2 to 12 years of age with asthma (reversible obstructive airway disease).

Albuterol Sulfate Inhalation Solution is contraindicated in patients with a history of hypersensitivity to any of its components.

The expected symptoms with overdosage are those of excessive beta-adrenergic stimulation and/or occurrence or exaggeration of symptoms such as seizures, angina, hypertension or hypotension, tachycardia with rates up to 200 beats per minute, arrhythmias, nervousness, headache, tremor, dry mouth, palpitation, nausea, dizziness, fatigue, malaise, insomnia, and exaggeration of the pharmacological effects listed in ADVERSE REACTIONS. Hypokalemia may also occur. As with all sympathomimetic aerosol medications, cardiac arrest and even death may be associated with abuse of Albuterol Sulfate Inhalation Solution. Treatment consists of discontinuation of Albuterol Sulfate Inhalation Solution together with appropriate symptomatic therapy. The judicious use of a cardioselective beta-receptor blocker may be considered, bearing in mind that such medication can produce bronchospasm. There is insufficient evidence to determine if dialysis is beneficial for overdosage of Albuterol Sulfate Inhalation Solution.

The oral median lethal dose of albuterol sulfate in mice is greater than 2000 mg/kg (approximately 580 times the maximum recommended daily inhalation dose of Albuterol Sulfate Inhalation Solution on a mg/m 2basis). The subcutaneous median lethal dose of albuterol sulfate in mature rats and small young rats is approximately 450 mg/kg and 2000 mg/kg, respectively (approximately 260 and 1200 times the maximum recommended daily inhalation dose of Albuterol Sulfate Inhalation Solution on a mg/m 2basis). The inhalation median lethal dose has not been determined in animals.

The usual starting dosage for patients 2 to 12 years of age is 1.25 mg or 0.63 mg of Albuterol Sulfate Inhalation Solution administered 3 or 4 times daily, as needed, by nebulization. More frequent administration is not recommended.

To administer 1.25 mg or 0.63 mg of albuterol, use the entire contents of one unit-dose vial (3 mL of 1.25 mg or 0.63 mg inhalation solution) by nebulization. Adjust nebulizer flow rate to deliver Albuterol Sulfate Inhalation Solution over 5 to 15 minutes.

The use of Albuterol Sulfate Inhalation Solution can be continued as medically indicated to control recurring bouts of bronchospasm. During this time most patients gain optimum benefit from regular use of the inhalation solution.

Patients 6 to 12 years of age with more severe asthma (baseline FEV 1less than 60% predicted), weight > 40 kg, or patients 11 to 12 years of age may achieve a better initial response with the 1.25 mg dose.

Albuterol Sulfate Inhalation Solution has not been studied in the setting of acute attacks of bronchospasm. A 2.5 mg dose of albuterol provided by a higher concentration product (2.5 mg albuterol per 3 mL) may be more appropriate for treating acute exacerbations, particularly in children 6 years old and above.

If a previously effective dosage regimen fails to provide the usual relief, medical advice should be sought immediately, as this is often a sign of seriously worsening asthma which would require reassessment of therapy.

The drug compatibility (physical and chemical), clinical efficacy and safety of Albuterol Sulfate Inhalation Solution, when mixed with other drugs in a nebulizer have not been established.

The safety and efficacy of Albuterol Sulfate Inhalation Solution have been established in clinical trials when administered using the Pari LC Plus™ nebulizer and Pari PRONEB™ compressor. The safety and efficacy of Albuterol Sulfate Inhalation Solution when administered with other nebulizer systems have not been established.

Albuterol Sulfate Inhalation Solution should be administered via jet nebulizer connected to an air compressor with adequate air flow, equipped with a mouthpiece or suitable face mask.

Albuterol Sulfate Inhalation Solution is supplied as a 3 mL, clear, colorless, sterile, preservative-free, aqueous solution in two different strengths, 0.63 mg/3 mL and 1.25 mg/3 mL, of albuterol (equivalent to 0.75 mg of albuterol sulfate or 1.5 mg of albuterol sulfate per 3 mL) in unit-dose low-density polyethylene (LDPE) vials. Each unit-dose LDPE vial is protected in a foil pouch, and each foil pouch contains 1, 5, or 25unit-dose LDPE vials.
