The 24-hour ambulatory blood pressure response to daily treatment with
verapamil sustained release (SR) 180 mg once daily, trandolapril 2 mg
once daily, or verapamil SR 180 mg/trandolapril 2 mg once daily was i
nvestigated in a randomized, double-masked study. This study consisted
of a subset of patients of a larger study. Ninety patients (mean age,
55 years) with moderate essential hypertension were enrolled in the s
tudy; 24 received verapamil SR 180 mg once daily, 35 received trandola
pril 2 mg once daily, and 31 received verapamil SR 180 mg/trandolapril
2 mg once daily therapy for 8 weeks. The 24-hour ambulatory blood pre
ssure measurements were done at baseline and at the end of the treatme
nt period. Treatment with verapamil SR/trandolapril combination therap
y produced significantly greater reductions in diastolic blood pressur
e (DBP) and systolic blood pressure (SBP) than either monotherapy over
the 24-hour period, and during the daytime and nighttime monitoring p
eriods (adjusted mean reduction in blood pressure over 24 hours: 18.1/
11.1 mm Hg vs 10.7/6.4 mm Hg on trandolapril monotherapy vs 6.9/6.7 mm
Hg on verapamil SR monotherapy. Blood pressure remained within the no
rmal range (DBP <90 mm Hg, SEP <140 mm Hg) longer on combination thera
py than on either monotherapy. Combination therapy had the most pronou
nced effect on blunting the early morning rise in blood pressure. Vera
pamil SR/trandolapril combination therapy may be an appropriate treatm
ent option in patients with moderate essential hypertension, particula
rly in those who have a tendency toward early morning rise in blood pr
essure.
