Azilsartan medoxomil plus chlorthalidone is superior to olmesartan plus hydrochlorothiazide for the treatment of stage 2 systolic hypertension, say researchers. In a triple-arm, double-blind study, Cushman et al. randomly allocated 1,071 participants to receive high-dose or low-dose azilsartan medoxomil plus chlorthalidone, or olmesartan medoxomil plus hydrochlorothiazide. Decreases in clinic and ambulatory systolic blood pressures were greater in both azilsartan medoxomil–chlorthalidone groups than in the olmesartan–hydrochlorothiazide group after 12 weeks.
