EFFICACY AND TOLERABILITY OF 5 MG OF CILAZAPRIL PLUS 12.5 MG OF HYDROCHLOROTHIAZIDE IN MILD-TO-MODERATE HYPERTENSION - RESULTS OF 24-HOUR AMBULATORY BLOOD-PRESSURE MONITORING
B. Martina et al., EFFICACY AND TOLERABILITY OF 5 MG OF CILAZAPRIL PLUS 12.5 MG OF HYDROCHLOROTHIAZIDE IN MILD-TO-MODERATE HYPERTENSION - RESULTS OF 24-HOUR AMBULATORY BLOOD-PRESSURE MONITORING, Journal of cardiovascular pharmacology, 24, 1994, pp. 190000089-190000092
The efficacy and tolerability of a fixed combination of 5 mg of cilaza
pril and 12.5 mg of hydrochlorothiazide against hypertension was evalu
ated in 36 patients (26 men and 10 women) between 33-68 years old. Twe
nty-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. Measure
ments 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 greater than or
equal to 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 w
eeks. After this period, a second 24-h ABPM was performed. Office bloo
d pressure measurements were taken at weeks -2, 0, 2, and 6. Routine l
aboratory blood samples were taken at weeks 0 and 6. Single blood pres
sure 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), an
d the mean diastolic pressure from 100 +/- 9 to 90 +/- 9 mm Hg (p < 0.
0001). Twenty-eight patients (80) responded to treatment (response cri
teria: mean diastolic daytime pressure at week 6 < 90 mm Hg and/or a d
ifference between weeks 0-6 greater than or equal to 5 mm Hg). A reduc
tion in blood pressure was observed throughout the 24-h period in the
systolic as well as the diastolic values. Treatment was well tolerated
; no significant changes in glucose, potassium, and creatinine values
were recorded and no adverse event necessitated premature discontinuat
ion of treatment. Data gained from 24-h ambulatory monitoring thus con
firm the efficacy and safety of a combination of 5 mg of cilazapril an
d 12.5 mg of hydrochlorothiazide.
