Lisinopril is a medication belonging to the drug class of angiotensin-converting enzyme (ACE) inhibitors and is used to treat hypertension (high blood pressure), heart failure, and heart attacks. [7] For high blood pressure it is usually a first-line treatment. It is also used to prevent kidney problems in people with diabetes mellitus. [7] Lisinopril is taken orally (swallowed by mouth). [7] Full effect may take up to four weeks to occur. [7]

Contents

Common side effects include headache, dizziness, feeling tired, cough, nausea, and rash. [7] Serious side effects may include low blood pressure, liver problems, hyperkalemia (high blood potassium), and angioedema. [7] Use is not recommended during the entire duration of pregnancy as it may harm the baby. [7] Lisinopril works by inhibiting the renin–angiotensin–aldosterone system. [7]

Lisinopril was patented in 1978 and approved for medical use in the United States in 1987. [7] [10] It is available as a generic medication. [7] In 2021, it was the fourth most commonly prescribed medication in the United States, with more than 88 million prescriptions. [11] [12] In July 2016, an oral solution formulation of lisinopril was approved for use in the United States. [7] [13]

Medical uses

Lisinopril is typically used for the treatment of high blood pressure, congestive heart failure, and diabetic nephropathy and after acute myocardial infarction (heart attack). [7] [1] Lisinopril is part of the ACE inhibitors drug class. [1] Lisinopril is indicated for the treatment of hypertension, adjunctive therapy for heart failure, and acute myocardial infarction. [1]

Contraindications

Lisinopril is contraindicated in people who have a history of angioedema (hereditary or idiopathic) or who have diabetes and are taking aliskiren. [1]

Adverse effects

Common side effects include headache, dizziness, feeling tired, cough, nausea, and rash. [7] Serious side effects may include low blood pressure, liver problems, hyperkalemia, and angioedema. [7] Use is not recommended during the entire duration of pregnancy as it may harm the baby. [7]

Pregnancy and breastfeeding

Animal and human data have revealed evidence of harm to the embryo and teratogenicity associated with ACE inhibitors. [1]

Interactions

Dental care

ACE-inhibitors like lisinopril are considered to be generally safe for people undergoing routine dental care, though the use of lisinopril prior to dental surgery is more controversial, with some dentists recommending discontinuation the morning of the procedure. [14] People may present to dental care suspicious of an infected tooth, but the swelling around the mouth may be due to lisinopril-induced angioedema, prompting emergency and medical referral. [14]

Pharmacology

Lisinopril is the lysine-analog of enalapril. Unlike other ACE inhibitors, it is not a prodrug, is not metabolized by the liver, and is excreted unchanged in the urine. [1]

Mechanism of action

Lisinopril is an ACE inhibitor, meaning it blocks the actions of angiotensin-converting enzyme (ACE) in the renin–angiotensin–aldosterone system (RAAS), preventing angiotensin I from being converted to angiotensin II. Angiotensin II is a potent direct vasoconstrictor and a stimulator of aldosterone release. Reduction in the amount of angiotensin II results in relaxation of the arterioles. Reduction in the amount of angiotensin II also reduces the release of aldosterone from the adrenal cortex, which allows the kidney to excrete sodium along with water into the urine, and increases retention of potassium ions. [15] Specifically, this process occurs in the peritubular capillaries of the kidneys in response to a change in Starling forces. [16] The inhibition of the RAAS system causes an overall decrease in blood pressure. [15]

Pharmacokinetics

Absorption

Following oral administration of lisinopril, peak serum concentrations of lisinopril occur within about seven hours, [1] [15] although there was a trend to a small delay in time taken to reach peak serum concentrations in acute myocardial infarction patients. The peak effect of lisinopril is about 6 hours after administration for most people. [17] [18] Declining serum concentrations exhibit a prolonged terminal phase, which does not contribute to drug accumulation. This terminal phase probably represents saturable binding to ACE and is not proportional to dose. Lisinopril does not undergo metabolism and absorbed drug is excreted unchanged entirely in the urine. Based on urinary recovery, the mean extent of absorption of lisinopril is approximately 25% (reduced to 16% in people with New York Heart Association Functional Classification (NYHA) Class II–IV heart failure), with large interpatient variability (6 to 60%) at all doses tested (5 to 80 mg). [1] [15] Lisinopril absorption is not affected by the presence of food in the gastrointestinal tract. [17] [19] [20]

Studies in rats indicate that lisinopril crosses the blood-brain barrier poorly. Multiple doses of lisinopril in rats result in little or no accumulation in brain tissue. [21]

Distribution

Lisinopril does not bind to proteins in the blood. [1] [15] It does not distribute as well in people with NYHA Class II–IV heart failure. [1] [15]

Elimination

Lisinopril leaves the body completely unchanged in the urine. [1] [15] The half-life of lisinopril is 12 hours, and is increased in people with kidney problems. [1] [15] While the plasma half-life of lisinopril has been estimated between 12 and 13 hours, the elimination half-life is much longer, at around 30 hours. [17] The full duration of action is between 24 and 30 hours. [17]

Lisinopril is the only water-soluble member of the ACE inhibitor class, and thus has no metabolism by the liver. [17]

Chemistry

Pure lisinopril powder is white to off white in color. [1] Lisinopril is soluble in water (approximately 13 mg/L at room temperature), [22] less soluble in methanol, and virtually insoluble in ethanol. [1]

History

Captopril, the first ACE inhibitor, is a functional and structural analog of a peptide derived from the venom of the jararaca, a Brazilian pit viper ( Bothrops jararaca ). [23] Enalapril is a derivative, designed by scientists at Merck to overcome the rash and bad taste caused by captopril. [24] [25] :12–13 Enalapril is actually a prodrug; the active metabolite is enalaprilat. [26]

The di-acid metabolite of enalapril, enalaprilat, and its lysine analogue lisinopril are potent inhibitors of angiotensin converting enzyme (ACE); they do not contain sulphydryl groups. Both drugs can be assayed by high pressure liquid chromatography and by radioimmunoassay and plasma ACE inhibition remains stable under normal storage conditions. It is therefore possible to study their pharmacokinetics as well as their pharmacodynamic effects in humans. Enalaprilat and lisinopril as well as ACE activity have been measured in blood taken during the course of two studies of the effects of these drugs on blood pressure and autonomic responsiveness.

Lisinopril is a synthetic peptide derivative of captopril. [22] Scientists at Merck created lisinopril by systematically altering each structural unit of enalaprilat, substituting various amino acids. Adding lysine at one end of the drug turned out to have strong activity and had adequate bioavailability when given orally; analogs of that compound resulted in lisinopril, which takes its name from the discovery with lysine. Merck conducted clinical trials, and the drug was approved for hypertension in 1987 and congestive heart failure in 1993. [26]

The discovery posed a problem, since sales of enalapril were strong for Merck, and the company did not want to diminish those sales. Merck ended up entering into an agreement with Zeneca under which Zeneca received the right to co-market lisinopril, and Merck received the exclusive rights to an earlier stage aldose reductase inhibitor drug candidate, a potential treatment for diabetes. Zeneca's marketing and brand name, "Zestril", turned out to be stronger than Merck's effort. [27] The drug became a blockbuster for AstraZeneca (formed in 1998), with annual sales in 1999 of $1.2B. [28]

The US patents expired in 2002. [28] Since then, lisinopril has been available under many brand names worldwide; it is also available in combination drugs with diuretic hydrochlorothiazide (as lisinopril/hydrochlorothiazide), and with calcium channel blocker amlodipine (as lisinopril/amlodipine).

Captopril, sold under the brand name Capoten among others, is an angiotensin-converting enzyme (ACE) inhibitor used for the treatment of hypertension and some types of congestive heart failure. Captopril was the first oral ACE inhibitor found for the treatment of hypertension. It does not cause fatigue as associated with beta-blockers. Due to the adverse drug event of causing hyperkalemia, as seen with most ACE Inhibitors, the medication is usually paired with a diuretic.

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, ACE inhibitors, angiotensin II receptor antagonists (ARBs), and beta blockers.

The special niche for the medication that differentiates it from the other members of the ACE Inhibitor drug class is that was specifically developed for the use for patients with renal impairment. This was through manipulation of the metabolism and excretion, and is seen that fifty percent of the drug is hepatobiliary cleared, which can compensate for diminished renal clearance. The remaining fifty percent is excreted in urine. It does not need dose adjustment.

In 2016, the American College of Cardiology/American Heart Association Task Force recommended it as a replacement for an ACE inhibitor or an angiotensin receptor blocker in people with heart failure with reduced ejection fraction.

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.
