Once daily enalapril in general practice patients with mild to moderate essential hypertension

Thirty-nine general practice patients with mild to moderate essential hypertension were treated with enalapril 10 to 40 mg once daily alone or in combination with hydrochlorothiazide 12.5 to 25 mg once daily for 20 weeks. Eighty-one percent of patients responded with a satisfactory reduction in supine diastolic blood pressure, and 58% became normotensive. No serious adverse clinical or laboratory effects were noted. Enalapril alone or in combination with low dose diuretic administered once daily was an effective alternative regimen for mild to moderate hypertension.
