Drug-Drug Interaction Study Between HUC2-565-A and HUC2-565-B

A Two Cohort, Single-sequence, Parallel, Open Label, Multiple Oral Dosing Phase 1 Clinical Trial to Evaluate the Safety and the Pharmacokinetic Drug-drug Interaction of HUC2-565-A and HUC2-565-B in Healthy Adult Volunteers

The purpose of this study is to evaluate a pharmacokinetic drug interaction and safety.

Cohort A: To evaluate the effect of S-Amlodipine on the pharmacokinetics of Azilsartan at steady state.

Cohort B: To evaluate the effect of Azilsartan on the pharmacokinetics of S-Amlodipine at steady state.
