Uses

INDICATIONS AND USAGE Hypertension: Quinapril and hydrochlorothiazide tablets, USP are indicated for the treatment of hypertension, to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions. These benefits have been seen in controlled trials of antihypertensive drugs from a wide variety of pharmacologic classes including the class to which this drug principally belongs. There are no controlled trials demonstrating risk reduction with quinapril and hydrochlorothiazide tablets.

Dosage

DOSAGE AND ADMINISTRATION As individual monotherapy, quinapril is an effective treatment of hypertension in once-daily doses of 10 mg to 80 mg and hydrochlorothiazide is effective in doses of 12.5 mg to 50 mg. In clinical trials of quinapril and hydrochlorothiazide combination therapy using quinapril doses of 2.5 mg to 40 mg and hydrochlorothiazide doses of 6.25 mg to 25 mg, the antihypertensive effects increased with increasing dose of either component. The side effects (see WARNINGS ) of quinapril are generally rare and apparently independent of dose; those of hydrochlorothiazide are a mixture of dose-dependent phenomena (primarily hypokalemia) and dose-independent phenomena (e.g., pancreatitis), the former much more common than the latter.

Side Effects

ADVERSE REACTIONS Quinapril and hydrochlorothiazide tablets have been evaluated for safety in 1571 patients in controlled and uncontrolled studies. Of these, 498 were given quinapril plus hydrochlorothiazide for at least 1 year, with 153 patients extending combination therapy for over 2 years. In clinical trials with quinapril and hydrochlorothiazide tablets, no adverse experience specific to the combination has been observed. Adverse experiences that have occurred have been limited to those that have been previously reported with quinapril or hydrochlorothiazide. Adverse experiences were usually mild and transient, and there was no relationship between side effects and age, sex, race, or duration of therapy.

Warnings

WARNING: FETAL TOXICITY When pregnancy is detected, discontinue quinapril and hydrochlorothiazide tablets 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 WARNINGS Anaphylactoid and Possibly Related Reactions: Presumably because angiotensin converting inhibitors affect the metabolism of eicosanoids and polypeptides, including endogenous bradykinin, patients receiving ACE inhibitors (including quinapril) may be subject to a variety of adverse reactions, some of them serious. Head and Neck Angioedema: Angioedema of the face, extremities, lips, tongue, glottis, and larynx has been reported in patients treated with ACE inhibitors and has been seen in 0.1% of patients receiving quinapril. In two similarly sized US postmarketing quinapril trials that, combined, enrolled over 3,000 black patients and over 19,000 non-blacks, angioedema was reported in 0.30% and 0.55% of blacks (in Study 1 and 2, respectively) and 0.39% and 0.17% of non-blacks. CONTRAINDICATIONS Quinapril and hydrochlorothiazide tablets are contraindicated in patients who are hypersensitive to quinapril or hydrochlorothiazide and in patients with a history of angioedema related to previous treatment with an ACE inhibitor. Quinapril and hydrochlorothiazide tablets is contraindicated in combination with a neprilysin inhibitor (e.g., sacubitril).
