TLDR The combination tablet of finasteride and doxazosin works the same as taking each drug separately.
The study aimed to evaluate the pharmacokinetic profile and bioequivalence of a fixed combination tablet containing finasteride (5 mg) and doxazosin (2 mg) compared to the individual administration of these drugs. Conducted as a randomized, crossover study with 30 subjects, the results showed no significant differences in the pharmacokinetic parameters (AUC0-72h, AUC0-∞, and Cmax) between the combination tablet and the single agents. The mean ratios of AUC0-72h/AUC0-∞ for finasteride and doxazosin were nearly 100%, indicating adequate sampling time and confirming bioequivalence. This suggests that the combination tablet does not alter the pharmacokinetics of the individual drugs, supporting its use in clinical practice.
