This study is to assess the safety and pharmacokinetic characteristics between co-administration of C52R1M with C52R2 and administration of AJU-C52H.

This is an open-label, randomized, single-dose, 2x2 crossover study in healthy subjects to assess the bioequivalence after taking the study drugs.

3. Those who are eligible for adequate blood pressure criteria during screening tests Systolic blood pressure: 90 to 139 mmHg Diastolic blood pressure: 60 to 89 mmHg
4. Those who have no congenital chronic disease or chronic disease requiring treatment and who have no pathological symptoms or findings
5. Those who are eligible for clinical trials based on laboratory (hematology, blood chemistry, serum, urine test) and 12-lead ECG results during screening tests
