PRISTINE: A Clinical Trial to Evaluate the Blood Pressure Control of Telmisartan or Losartan in Essential Hypertensive Patients With Metabolic Syndrome
Study Details
Study Description
Brief Summary
This is a multi-center, randomized, open-label, active comparator-controlled, phase 4 clinical trial to evaluate the blood pressure control of Telmisartan or Losartan in essential hypertensive patients with metabolic syndrome
| Condition or Disease | Intervention/Treatment | Phase |
|---|---|---|
| Phase 4 |
Detailed Description
Participants were randomly assigned in a 1:1 ratio to the following group; the test group [Telmisartan 40 mg + S-Amlodopine 2.5 mg], the control group [Losartan 50 mg + S-Amlodopine 2.5 mg]. If the blood pressure measured at 6 weeks time (Visit 3) based on the random allocation date (Visit 2) is MSSBP ≥140 mmHg or MSDBP ≥90 mmHg, the test group will increase the Telmisartan 80 mg, the control group will increase the dose to 100 mg for 6 weeks from Visit 3 to Visit 4(End of study). However, if the need of dose increasing is not required according to the investigator's judgment, the current dose can be maintained. All clinical trial drugs are administered orally once a day, and it is recommended to be administered at the same time(am) for 12 weeks.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Telmisartan Telmitrend Tab.(Telmisartan) 40mg(80mg) + Anydipine-S(S-amlodipine) Tab. 2.5mg |
Drug: Telmisartan
Subjects assigned to the test group are oral administered Telmisartan 40 mg and S-Amlodopine 2.5 mg once a day for 12 weeks. However, if the blood pressure measured at 6 weeks after random allocation (Visit 3) is MSSBP ≥140 mmHg or MSDBP ≥ 90 mmHg, increase the dose to Telmisartan 80 mg for 6 weeks from Visit 3 to Visit 4 (End of study). However, if the need of dose increasing is not required according to the tester's judgment, the current dose can be maintained.
|
| Active Comparator: Losartan Cozaar Tab.(Losartan) 50mg(100mg) + Anydipine-S(S-amlodipine) Tab. 2.5mg |
Drug: Losartan
Subjects assigned to the control group are oral administered Losartan 50 mg and S-Amlodopine 2.5 mg once a day for 12 weeks. However, if the blood pressure measured at 6 weeks after random allocation (Visit 3) is MSSBP ≥140 mmHg or MSDBP ≥ 90 mmHg, increase the dose to Losartan 100 mg for 6 weeks from Visit 3 to Visit 4 (End of study). However, if the need of dose increasing is not required according to the tester's judgment, the current dose can be maintained.
