In a recent meta-regression analysis based on 30 hypertension trials with 149,407 patients, differences in achieved SBP were found to largely account for cardiovascular outcomes.2 1.

All active treatments reduced BP significantly (p0.001) versus placebo at all time points. A greater antihypertensive effect of irbesartan 300 mg once daily compared with losartan 100 mg once daily was present throughout the study. At Week 8, reductions from baseline in trough seated diastolic BP (SeDBP), the primary endpoint of the trial, were significantly greater with irbesartan 300 mg, compared with losartan 100 mg by 3.0 mmHg (-11.7 vs. -8.7 mmHg; p0.01). The difference in SeDBP between these 2 groups was also statistically significant at Weeks 1 (p0.01) and 4 (p0.02). Irbesartan 150 mg produced overall changes in SeDBP comparable to losartan 100 mg.10 Both drugs were well-tolerated. * Reductions in trough SeSBP at Week 8 were also significantly greater with irbesartan 300 mg, compared with losartan 100 mg (p0.01), by 5.1 mmHg (-16.4 vs.
