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 molecular formula is (C 13 H 21 NO 3 ) 2 • H 2 SO 4 . Albuterol sulfate USP is a white or practically white powder, freely soluble in water, slightly soluble in alcohol, in ether and practically insoluble in chloroform. 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 and sulfuric acid in a 3-mL isotonic, sterile, aqueous solution. Sodium chloride is added to adjust isotonicity of the solution 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 TM nebulizer (with face mask or mouthpiece) connected to a Pari PRONEB TM 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 ). albuterol-str
