Evaluation of reference-scaled average bioequivalence of two oral formulations of abiraterone acetate in healthy Chinese subjects .

Objective: This study was designed to evaluate the pharmacokinetic (PK) properties and bioequivalence (BE) of two 250-mg tablet formulations of abiraterone acetate: a newly developed generic formulation (test) and a branded formulation (reference) in healthy adult Chinese subjects under fasted (n = 40) and fed (n = 40) conditions.

Materials And Methods: The comparison was performed using a single-dose, open, randomized, and four-way replicate study. The concentration of abiraterone in blood samples taken over 48 hours was determined by liquid chromatography tandem mass spectrometry (LC-MS/MS).

Bioequivalence and Pharmacokinetic Profiles of Agomelatine 25-mg Tablets in Healthy Chinese Subjects: A Four-Way Replicate Crossover Study Demonstrating High Intra- and Inter-Individual Variations.

The present study was designed to assess the bioequivalence of two agomelatine formulations (25-mg tablets) in healthy Chinese male subjects. This single-dose, open-label, randomized, four-way replicate study with a 1-week washout period was conducted in 60 healthy Chinese male volunteers under fasting conditions. Blood samples were collected over a 12-h period after a single dose of the 25-mg agomelatine test (T) formulation or a reference (R) formulation, and the drug concentrations were assayed by liquid chromatography tandem mass spectrometry (LC-MS/MS).
