Description
11 DESCRIPTION Levalbuterol inhalation solution, USP (concentrate) is a sterile, clear, colorless, preservative-free solution of the hydrochloride salt of levalbuterol, the (R)-enantiomer of the drug substance racemic albuterol. Levalbuterol hydrochloride is a relatively selective beta 2 -adrenergic receptor agonist [see Clinical Pharmacology (12) ] . The chemical name for levalbuterol hydrochloride is (R)-α 1 -[[(1,1-dimethylethyl)amino]methyl]-4-hydroxy-1,3-benzenedimethanol hydrochloride, and its established chemical structure is as follows: The molecular weight of levalbuterol hydrochloride is 275.8, and its molecular formula is C 13 H 21 NO 3 •HCl. It is a white to off-white, crystalline solid, with a melting point of approximately 187°C and solubility of approximately 180 mg/mL in water. Levalbuterol hydrochloride is the USAN modified name for (R)-albuterol hydrochloride in the United States. Levalbuterol inhalation solution (concentrate) is supplied in 0.5 mL individually-wrapped unit-dose vials that must be diluted with normal saline before administration by nebulization. Each 0.5 mL unit-dose vial contains 1.25 mg of levalbuterol (as 1.44 mg of levalbuterol hydrochloride), sodium chloride to adjust tonicity, edetate disodium (EDTA) as a chelating agent and sulfuric acid to adjust the pH to 4.0 (3.3 to 4.5).

How Supplied
16 HOW SUPPLIED/STORAGE AND HANDLING Levalbuterol Inhalation Solution, USP (Concentrate) is supplied in 0.5 mL unit-dose, low-density polyethylene (LDPE) vials as a clear, colorless, sterile, preservative-free, aqueous solution. Each vial contains 1.25 mg/0.5 mL of levalbuterol (as 1.44 mg of levalbuterol hydrochloride) and is available in a shelf-carton containing 30 (NDC 0378-6993-93) individually wrapped foil pouches, each containing one unit-dose vial. Store levalbuterol inhalation solution (concentrate) in the protective foil pouch at 20° to 25°C (68° to 77°F). [See USP Controlled Room Temperature.] Protect from light and excessive heat. Open the foil pouch just prior to administration. Once the foil pouch is opened, the contents of the vial should be used immediately. Discard any vial if the solution is not colorless. Dilute levalbuterol inhalation solution (concentrate) with sterile normal saline before administration by nebulization.
Indications & Usage
1 INDICATIONS AND USAGE Levalbuterol inhalation solution (concentrate) is indicated for the treatment or prevention of bronchospasm in adults, adolescents, and children 6 years of age and older with reversible obstructive airway disease. Levalbuterol inhalation solution (concentrate) is a beta 2 -adrenergic agonist indicated for: • Treatment or prevention of bronchospasm in adults, adolescents, and children 6 years of age and older with reversible obstructive airway disease.

Dosage and Administration
2 DOSAGE AND ADMINISTRATION Levalbuterol inhalation solution (concentrate) is for oral inhalation only. Dilute with sterile normal saline before administration. Administer by nebulization using with a standard jet nebulizer (with a face mask or mouthpiece) connected to an air compressor. Do not exceed recommended dose. For dosages less than 1.25 mg, the non-concentrate (i.e., levalbuterol inhalation solution, 3 mL) formulation must be used. Children 6 to 11 Years Old: The recommended dosage of levalbuterol inhalation solution for patients 6 to 11 years old is 0.31 mg administered three times a day, by nebulization. Routine dosing should not exceed 0.63 mg three times a day. Adults and Adolescents ≥ 12 Years Old: The recommended starting dosage of levalbuterol inhalation solution for patients 12 years of age and older is 0.63 mg administered three times a day, every 6 to 8 hours, by nebulization. Patients 12 years of age and older with more severe asthma or patients who do not respond adequately to a dose of 0.63 mg of levalbuterol inhalation solution may benefit from a dosage of 1.25 mg three times a day. Patients receiving the highest dose of levalbuterol inhalation solution should be monitored closely for adverse systemic effects, and the risks of such effects should be balanced against the potential for improved efficacy. The use of levalbuterol inhalation solution can be continued as medically indicated to help control recurring bouts of bronchospasm. During this time, most patients gain optimal benefit from regular use of the inhalation solution. If a previously effective dosage regimen fails to provide the usual response this may be a marker of destabilization of asthma and requires reevaluation of the patient and the treatment regimen, giving special consideration to the possible need for anti-inflammatory treatment, e.g., corticosteroids. The drug compatibility (physical and chemical), efficacy, and safety of levalbuterol inhalation solution when mixed with other drugs in a nebulizer have not been established. The safety and efficacy of levalbuterol inhalation solution have been established in clinical trials when administered using the PARI LC Jet™ and PARI LC Plus™ nebulizers, and the PARI Master ® Dura-Neb ® 2000 and Dura-Neb ® 3000 compressors. The safety and efficacy of levalbuterol inhalation solution when administered using other nebulizer systems have not been established. • FOR ORAL INHALATION ONLY ( 2 ) • Dilute levalbuterol inhalation solution (concentrate) with sterile normal saline before administration by nebulization. • Children 6 to 11 Years Old: 0.31 mg administered three times a day, by nebulization.
