Abstract/OtherAbstract:
A previous meta-analysis of six randomized head-to-head trials suggests that the blood pressure (BP)-lowering capabilities of telmisartan may be comparable to those of valsartan. We performed an updated meta-analysis of telmisartan vs. valsartan therapy for the reduction of BP in hypertensive patients. MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials were searched through August 2012 using web-based search engines (PubMed, OVID). Eligible studies were prospective randomized controlled trials examining telmisartan vs. valsartan therapy and reporting clinic BP as an outcome. For each study, the data regarding changes from baseline to final clinic systolic BP (SBP) and diastolic BP (DBP) in both the telmisartan and valsartan groups were used to generate mean differences (MDs) and 95% confidence intervals (CIs). Of the 62 potentially relevant articles initially screened, 17 reports about prospective randomized controlled clinical trials of telmisartan vs. valsartan therapy, including a total of 5422 patients with hypertension, were identified and included. Pooled analysis suggested significant differences in BP reductions among the patients randomized to telmisartan vs. valsartan therapy (MD for SBP, -2.04 mm Hg; 95% CI, -2.80 to -1.28 mm Hg; P<0.00001; MD for DBP, -1.08 mm Hg; 95% CI, -1.55 to -0.62 mm Hg; P<0.00001). When data from the monotherapy and combination therapy (with hydrochlorothiazide) trials were pooled separately, telmisartan therapy was associated with a statistically significant difference in BP reductions relative to valsartan therapy in both the monotherapy and combination therapy groups. In conclusion, telmisartan therapy appears to reduce BP more than valsartan therapy in patients with hypertension.Hypertension Research advance online publication, 24 January 2013; doi:10.1038/hr.2012.233.
