(captopril and hydrochlorothiazide tablets, USP)
CAPOZIDE® (captopril and hydrochlorothiazide tablets, USP) for oral administration combines two antihypertensive agents: CAPOTEN® (captopril) and hydrochlorothiazide. Captopril, the first of a new class of antihypertensive agents, is a specific competitive inhibitor of angiotensin I-converting enzyme (ACE), the enzyme responsible for the conversion of angiotensin I to angiotensin II. Hydrochlorothiazide is a benzothiadiazide (thiazide) diuretic-antihypertensive.
CAPOZIDE® (captopril and hydrochlorothiazide tablets, USP) is indicated for the treatment of hypertension. The blood pressure lowering effects of captopril and thiazides are approximately additive.
This fixed combination drug may be used as initial therapy or substituted for previously titrated doses of the individual components.
When captopril and hydrochlorothiazide are given together it may not be necessary to administer captopril in divided doses to attain blood pressure control at trough (before the next dose). Also, with such a combination, a daily dose of 15 mg of hydrochlorothiazide may be adequate.
Treatment may, therefore, be initiated with CAPOZIDE® 25 mg/15 mg once daily. Subsequent titration should be with additional doses of the components (captopril, hydrochlorothiazide) as single agents or as CAPOZIDE® 50 mg/15 mg, 25 mg/25 mg, or 50 mg/25 mg (see DOSAGE AND ADMINISTRATION).
In using CAPOZIDE®, consideration should be given to the risk of neutropenia/agranulocytosis (see WARNINGS).
CAPOZIDE® may be used for patients with normal renal function, in whom the risk is relatively low. In patients with impaired renal function, particularly those with collagen vascular disease, CAPOZIDE® should be reserved for hypertensives who have either developed unacceptable side effects on other drugs, or have failed to respond satisfactorily to other drug combinations.
ACE inhibitors (for which adequate data are available) cause a higher rate of angioedema in black than in non-black patients (see WARNINGS: Captopril: Head and Neck Angioedema and Intestinal Angioedema).
