AccuNeb® (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 beta2-adrenergic bronchodilator (see CLINICAL
PHARMACOLOGY). The chemical name for albuterol sulfate is α1 [(tert-butylamino)
methyl]-4-hydroxy-mxylene-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
Albuterol sulfate is a white crystalline powder, soluble in water and slightly
soluble in ethanol. The World Health Organization recommended name for albuterol
AccuNeb (albuterol sulfate) Inhalation Solution is supplied in two strengths
in unit dose vials. Each unit dose vial contains either 0.75 mg of albuterol
sulfate (equivalent to 0.63 mg of albuterol) or 1.50 mg of albuterol sulfate
(equivalent to 1.25 mg of albuterol) 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).
AccuNeb (albuterol sulfate) Inhalation Solution does not require dilution prior
to administration by nebulization. For AccuNeb (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. AccuNeb (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).
