WARNING: FETAL TOXICITY
When pregnancy is detected, discontinue ACCURETIC as soon as possible.
Drugs that act directly on the renin-angiotensin system can cause injury and death to the developing fetus. See Warnings: Fetal Toxicity
ACCURETIC is a fixed-combination tablet that combines an angiotensin-converting enzyme (ACE) inhibitor, quinapril hydrochloride, and a thiazide diuretic, hydrochlorothiazide.
ACCURETIC is indicated for the treatment of hypertension. This fixed combination is not indicated for the initial therapy of hypertension (see
DOSAGE AND ADMINISTRATION).
In using ACCURETIC, consideration should be given to the fact that another angiotensin-converting enzyme inhibitor, captopril, has caused agranulocytosis, particularly in patients with renal impairment or collagen-vascular disease. Available data are insufficient to show that quinapril does not have a similar risk (see
Angioedema in Black Patients
Black patients receiving ACE inhibitor monotherapy have been reported to have a higher incidence of angioedema compared to non-blacks. It should also be noted that in controlled clinical trials, ACE inhibitors have an effect on blood pressure that is less in black patients than in non-blacks.
