Subject PK blood samples will be taken prior to dosing and at multiple time points, up to 8 hours after dosing during each treatment period. PK samples will be analyzed using a validated test method. Area under the curve of the drug concentration versus time curve (AUC\[0-t\]) for each treatment period will be calculated using the trapezoidal rule.
Subject PK blood samples will be taken prior to dosing and at multiple time points, up to 8 hours after dosing during each treatment period. PK samples will be analyzed using a validated test method. Peak plasma concentration (C\[max\]) will be the highest concentration of Albuterol during each treatment period.
Subject PK blood samples will be taken prior to dosing and at multiple time points, up to 8 hours after dosing during each treatment period. PK samples will be analyzed using a validated test method. Time to reach peak plasma concentration (t\[max\]) will be the time it takes to reach the highest concentration of Albuterol during each treatment period.
Subject PK blood samples will be taken prior to dosing and at multiple time points, up to 8 hours after dosing during each treatment period. PK samples will be analyzed using a validated test method. Plasma Albuterol concentrations at these time points will be reported during each treatment period.
The forced expiratory volume in the 1st second (FEV1) is measured with a clinically accepted model of spirometer. Subjects perform a pre-dose baseline FEV1 prior to dosing and perform subsequent FEV1 tests at 5, 15 and 30 minutes and 1, 1.5, 2, 3, 4, 5, and 6 hours after dosing during each treatment period. Area under the curve (AUC), from baseline to 6 hours post-dose, for the treatment period is calculated using the trapezoidal rule. Statistical analysis is performed using a one-sided t-test.

A006 DPI is an investigational dry powder inhaler being developed for the treatment of asthma. It is a small molecule therapy administered via inhalation. The drug is currently in Phase 2 clinical development, with completed trials evaluating its efficacy, dose-ranging, safety, and pharmacokinetics in patients with asthma and healthy volunteers.
A006 DPI is being developed by Amphastar Pharmaceuticals, Inc., a company traded on the Nasdaq under the ticker symbol AMPH. The company is conducting clinical trials for this investigational asthma treatment in the United States.
A006 DPI is in Phase 2 clinical development. Two Phase 2 trials have been completed, both in the United States. The drug is investigational and has not been approved by the FDA. Its safety and efficacy are still being evaluated in clinical studies.
A006 DPI has completed two Phase 2 clinical trials. NCT02210806 evaluated efficacy, dose-ranging, and safety in 22 asthma patients. NCT02271334 evaluated pharmacokinetics and safety in 22 healthy volunteers. Both trials were randomized, double-blind, and active-controlled, with a combined enrollment of 44 participants.
A006 DPI is a dry powder inhaler formulation of albuterol, a short-acting beta-agonist that works by relaxing the muscles in the airways to improve breathing. It is delivered via inhalation for the treatment of asthma. The drug targets beta-2 adrenergic receptors in the lungs to produce bronchodilation.
