The safety and efficacy of sustained-release diltiazem 120 to 180 mg, 2 times a day, were compared with hydrochlorothiazide 25 to 50 mg, 2 times a day, and the combination of diltiazem and hydrochlorothiazide in 56 patients with mild to moderate hypertension (supine diastolic blood pressure between 95 and 114 mm Hg) using a placebo-controlled, parallel-design protocol. Data from an additional 21 patients were evaluated for safety only. The data reported herein represent the preliminary experience from a larger 200-patient multicenter study. All patients received placebo for 4 weeks, followed by either hydrochlorothiazide or diltiazem titrated to achieve a diastolic blood pressure reduction of greater than or equal to 10 mm Hg to reach a goal supine diastolic blood pressure of less than 90 mm Hg. Patients not achieving the treatment goal received hydrochlorothiazide plus diltiazem. At week 14, on maintenance monotherapy, diltiazem and hydrochlorothiazide produced comparable reductions in blood pressure from placebo baseline (160.3 +/- 24.3/101.7 +/- 5.5 to 145.2 +/- 24.1/89.8 +/- 7.4 mm Hg with diltiazem, 156.0 +/- 15.6/103.7 +/- 4.7 to 134.1 +/- 12.5/89.2 +/- 9.5 mm Hg with hydrochlorothiazide, p less than 0.001 for both). Diltiazem and hydrochlorothiazide achieved goal blood pressure in 42% and 45% of patients, respectively. The effects in responders were sustained for 6 months. In patients who did not achieve the treatment goal, 63% responded to diltiazem plus hydrochlorothiazide.No clinically significant postural hypotension was observed on any regimen. Heart rate was slightly lower with diltiazem than with hydrochlorothiazide. Adverse effects were minimal with diltiazem, hydrochlorothiazide and diltiazem plus hydrochlorothiazide but more hypokalemia occurred with hydrochlorothiazide.(ABSTRACT TRUNCATED AT 250 WORDS)
