简要总结
This study was designed to assess the bioequivalence between the test products (Albuterol Sulfate Inhalation Aerosol 108 mcg Per Actuation) and the reference products (Proair HFA [Albuterol Sulfate] Inhalation Aerosol 90 mcg Per Actuation) in healthy volunteers under fasting conditions. The test product was considered bioequivalent to the reference product if the T/R ln-transformed AUC(0-t), AUC(0-inf), and Cmax were within 80.00-125.00% of those of the reference.
详细描述
A single-dose, randomized, open-label, two-period, two-sequence, two-treatment, single-centre, crossover bioequivalence study was carried out under fasting conditions in healthy adults, aged 20-60 years. For each period, each subject received a single dose as equivalent to 180 mcg of albuterol of the study drugs according to the pre-determined randomization scheme. Each subject was drawn 22 times over the period of 24 hours. Plasma samples were collected and analyzed for albuterol concentrations by using LC-MS/MS. For each subject, there were 2 dosing periods separated by a 14-day washout period. During the study, standardized meals were provided to all subjects while institutionalized.
