Popis: In a double-blind, parallel-group multicentre study, the efficacy and safety of a fixed low-dose combination of ramipril 2.5 mg and hydrochlorothiazide (HCT) 12.5 mg was compared with each of the component drugs when given as monotherapy. After a four-week placebo run-in, patients were randomized to receive either ramipril 2.5 mg (n = 218) or HCT 12.5 mg (n = 220), or the fixed-dose combination of ramipril 2.5 mg and HCT 12.5 mg (n = 222), for a period of eight weeks. At the end of the study, in which 624 patients had completed treatment, it was found that the decrease in supine diastolic blood pressure (the main efficacy parameter) was greater in the ramipril-HCT combination group than in either the ramipril or the HCT monotherapy groups, the difference being statistically significant when compared with the HCT group (-14.3, -13.1 and -12.4 mm Hg, respectively). Reductions in standing DBP and supine and standing systolic blood pressure (SBP) were also greatest in the combination group. The incidence of adverse events was lower in the combination group than in either of the monotherapy groups, and there were no serious clinically significant laboratory abnormalities in the combination group.
