Levalbuterol HCl is a relatively selective beta 2 -adrenergic receptor agonist [see Clinical Pharmacology (12) ]. The chemical name for levalbuterol HCl 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 HCl is 275.8, and its empirical 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 HCl is the USAN modified name for (R)-albuterol HCl in the United States. Levalbuterol HCl inhalation solution is supplied in unit-dose vials and requires no dilution before administration by nebulization. Each 3 mL unit-dose vial contains 0.31 mg of levalbuterol (as 0.36 mg of levalbuterol HCl) or 0.63 mg of levalbuterol (as 0.73 mg of levalbuterol HCl) or 1.25 mg of levalbuterol (as 1.44 mg of levalbuterol HCl), sodium chloride to adjust tonicity, and sulfuric acid to adjust the pH to 4.0 (3.3 to 4.5). The chemical structure for levalbuterol HCl is (R)-α1-[[(1,1-dimethylethyl)amino]methyl]-4-hydroxy-1,3-benzenedimethanol hydrochloride.

Dosage and Administration
2 DOSAGE AND ADMINISTRATION Levalbuterol HCl inhalation solution is for oral inhalation only. 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. Children 6 to 11 years old: The recommended dosage of levalbuterol HCl inhalation solution for patients 6-11 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 HCl 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 HCl inhalation solution may benefit from a dosage of 1.25 mg three times a day. Patients receiving the highest dose of levalbuterol HCl 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 HCl 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 HCl inhalation solution when mixed with other drugs in a nebulizer have not been established. The safety and efficacy of levalbuterol HCl 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 HCl inhalation solution when administered using other nebulizer systems have not been established. FOR ORAL INHALATION ONLY ( 2 ) Children 6 to 11 years old: 0.31 mg administered three times a day, by nebulization. Routine dosing should not exceed 0.63 mg three times a day.
