The anti hypertensive efficacy and tolerability of on ce-daily adminis
tration of a fixed-dose combination of lisinopril 20 mg/hydrochlorothi
azide 12.5 mg was assessed in a population of 10,525 patients containi
ng a high proportion of hypertensive obese subjects. The majority of t
hese patients had been inadequately treated with a variety of antihype
rtensive drugs. The study treatment produced a further fall in diastol
ic blood pressure with once-daily administration for 3 months. Seventy
-seven percent of the patients achieved the target diastolic pressure
less than or equal to 90 mmHg. The combination of lisinopril 20 mg/hyd
rochlorothiazide 12.5 mg was effective and well tolerated in a populat
ion of obese hypertensive patients with high incidence of concomitant
medical conditions. Adverse events were infrequent as were withdrawals
from treatment. (C) 1995 Wiley-Liss, Inc.
