A Clinical Trial to Evaluate the Blood Pressure Control of Telmisartan or Losartan in Essential Hypertensive Patients With Metabolic Syndrome

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.

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.
