Abstract

Hypertension is a global health problem. Multiple classes of drugs including angiotensin receptor blockers (ARBs) are available for the treatment of hypertension. Olmesartan is a relatively newer ARB used in hypertension management.To assess the efficacy and safety of WIN-BP (Olmesartan 20 mg/40 mg) tablet in Indian patients with hypertension.An open label, non-comparative, multi-centric, real world post marketing observational study included Indian adult hypertensive patients who were treated with olmesartan 20 mg/40 mg tablet once daily for six months. The primary outcome was reduction of systolic blood pressure (SBP) to <140 mmHg and diastolic BP (DBP) to <90 mmHg at 3 and 6 months after initiation of treatment with olmesartan. All reported adverse events were recorded.A total of 8940 patients were enrolled in this study. Baseline SBP of 164 mmHg was reduced to 153, 145, 134 and 130 mmHg at the end of 15 days, 1, 3 and 6 months respectively. Similarly, baseline DBP of 100 mmHg was reduced to 93, 89, 84 and 82 mmHg at the end of 15 days, 1, 3 and 6 months respectively. The reduction in both systolic and diastolic blood pressure from day 15 to month 6 was statistically significant (p < 0.0001) with olmesartan treatment. The percentage of responders for both systolic and diastolic blood pressure increased consistently from day 15 to month 6. Only 0.08% patients reported the adverse events. No serious adverse event was reported in the study.Olmesartan 20 mg/40 mg is effective and well tolerated without any serious adverse events in patients with hypertension.Copyright © 2014 Cardiological Society of India.
