Quinapril, sold under the brand name Accupril [2] by the Pfizer corporation, is a medication used to treat high blood pressure (hypertension), heart failure, and diabetic kidney disease. [1] [3] It is a first line treatment for high blood pressure. [3] It is taken by mouth. [1] [3]

Contents

Common side effects include headaches, dizziness, feeling tired, and cough. [3] Serious side effects may include liver problems, low blood pressure, angioedema, kidney problems, and high blood potassium. [3] Use in pregnancy and breastfeeding is not recommended. [4] It is among a class of drugs called ACE inhibitors and works by decreasing renin-angiotensin-aldosterone system activity. [3]

Quinapril was patented in 1980 and came into medical use in 1989. [5] It is available as a generic medication. [6] In 2020, it was the 253rd most commonly prescribed medication in the United States, with more than 1 million prescriptions. [7] [8]

Medical uses

Quinapril is indicated for the treatment of high blood pressure (hypertension) and as adjunctive therapy in the management of heart failure. [1] It may be used for the treatment of hypertension by itself or in combination with thiazide diuretics, and with diuretics and digoxin for heart failure. [1]

Contraindications

Contraindications include: [9]

Side effects

Side effects of Quinapril [9] include dizziness, cough, vomiting, upset stomach, angioedema, and fatigue.

Mechanism of action

Quinapril inhibits angiotensin converting enzyme, an enzyme which catalyses the formation of angiotensin II from its precursor, angiotensin I. Angiotensin II is a powerful vasoconstrictor and increases blood pressure through a variety of mechanisms. Due to reduced angiotensin production, plasma concentrations of aldosterone are also reduced, resulting in increased excretion of sodium in the urine and increased concentrations of potassium in the blood.

Partial Recall

In April of 2022, Pfizer voluntarily recalled five batches of the drug because of the presence of a nitrosamine, NNitroso-quinapril. Testing found that the amount of nitrosamines was above the acceptable daily intake level (all humans are exposed to nitrosamines up to a certain daily level by cured and grilled meats, water, dairy products, and vegetables) set by the U.S.'s Food and Drug Administration (FDA). Though long-term ingestion of NNitroso-quinapril potentially might cause cancer in some individuals, there is not believed to be an imminent risk of harm. [10] [11]

<span class="mw-page-title-main">ACE inhibitor</span> Class of medications used primarily to treat high blood pressure

Angiotensin-converting-enzyme inhibitors are a class of medication used primarily for the treatment of high blood pressure and heart failure. This class of medicine works by causing relaxation of blood vessels as well as a decrease in blood volume, which leads to lower blood pressure and decreased oxygen demand from the heart.

Antihypertensives are a class of drugs that are used to treat hypertension. Antihypertensive therapy seeks to prevent the complications of high blood pressure, such as stroke, heart failure, kidney failure and myocardial infarction. Evidence suggests that reduction of the blood pressure by 5 mmHg can decrease the risk of stroke by 34% and of ischaemic heart disease by 21%, and can reduce the likelihood of dementia, heart failure, and mortality from cardiovascular disease. There are many classes of antihypertensives, which lower blood pressure by different means. Among the most important and most widely used medications are thiazide diuretics, calcium channel blockers, angiotensin-converting enzyme inhibitors (ACEis), angiotensin II receptor blockers or antagonists (ARBs), and beta blockers.

An ACE inhibitor and thiazide combination is a drug combination used to treat hypertension. They are given by mouth. ACE inhibitors reduce the activity of angiotensin-converting enzyme (ACE) which produces angiotensin II, a hormone that constricts blood vessels. Thiazides are a class of diuretics that inhibit the thiazide receptor, thereby increasing urine production and reducing excess water and salt in the body. Several organizations recommend combination therapy for hypertension in cases of failure of a single drug to achieve target blood pressure, or even as a first line treatment for some patients.
