In a pooled analysis of two similar 8 week double-blind placebo-controlled clinical trials vs. valsartan/ hydrochlorothiazide 160 mg/ 25 mg (n=2121 patients evaluated for efficacy) a significantly greater blood pressure lowering effect of 2.2/ 1.2 mm Hg (SBP/ DBP) was demonstrated (difference in adjusted mean changes from baseline, respectively) in favour of telmisartan/ hydrochlorothiazide 80 mg/ 25 mg combination.
