Effects of the combination of low-dose nifedipine GITS 20 mg and losartan 50 mg in patients with mild to moderate hypertension.

Most hypertensive patients require more than one medication to effectively control elevated blood pressure (BP) values. This multicenter, randomized, double-blind study was aimed at testing the efficacy and safety of the combination of low-dose nifedipine GITS 20 mg/ losartan 50 mg compared with either monotherapy in patients with grade 1 to 3 hypertension over an eight-week period. Of 352 patients enrolled in the study, 300 were randomized.
