Evaluation of the Pharmacokinetics of Abiraterone Acetate and Abiraterone Following Single-Dose Administration of Abiraterone Acetate to Healthy Subjects

Background and Objective Following oral administration of abiraterone acetate, the parent compound abiraterone acetate is rapidly metabolized to abiraterone. To our knowledge, bioanalytical methods to date have not been able to detect the parent compound in human plasma, and bioassay was only performed on the metabolite. A highly sensitive bioanalytical method was developed and validated to measure plasma concentrations of the parent compound. In this study, both analytes were assayed and used to evaluate the full pharmacokinetic profile of abiraterone acetate tablets.
