The efficacy and tolerability of a fixed combination of 5 mg of cilazapril and 12.5 mg of hydrochlorothiazide against hypertension was evaluated in 36 patients (26 men and 10 women) between 33-68 years old. Twenty-two had newly diagnosed hypertension and 14 had previously treated hypertension. Twenty-four-hour noninvasive ambulatory blood pressure monitoring (ABPM) was performed after a 2-week washout period. Measurements were taken at 20-min intervals during the day (from 8 a.m. to 10 p.m.) and at 30-min intervals during the night (from 10 p.m. to 8 a.m.). Patients with a mean diastolic daytime pressure of > or = 90 < 115 mg Hg were then given 5 mg of cilazapril plus 12.5 mg of hydrochlorothiazide once daily between 6 a.m. and 8 a.m. for 6 weeks. After this period, a second 24-h ABPM was performed. Office blood pressure measurements were taken at weeks -2, 0, 2, and 6. Routine laboratory blood samples were taken at weeks 0 and 6. Single blood pressure readings did not change significantly during the washout period (between weeks -2 and 0). The ABPM 24-h mean systolic pressure changed between weeks 0-6 from 143 +/- 13 to 126 +/- 11 mm Hg (p < 0.0001), and the mean diastolic pressure from 100 +/- 9 to 90 +/- 9 mm Hg (p < 0.0001). Twenty-eight patients (80) responded to treatment (response criteria: mean diastolic daytime pressure at week 6 < 90 mm Hg and/or a difference between weeks 0-6 > or = 5 mm Hg).
