An Open-label, Multiple Dose, Crossover Study to Evaluate the Drug-drug Interaction Between AJU-A51R1 and AJU-A51R2 in Healthy Volunteers

To evaluate a pharmacokinetic drug interaction between AJU-A51R1 and AJU-A51R2 in healthy male volunteers.

This study is to investigate drug-drug interaction between AJU-A51R1 and AJU-A51R2.
