Generic Enalapril Information

Introduction

Enalapril is an angiotensin‑converting enzyme (ACE) inhibitor used primarily to lower high blood pressure and to treat heart failure. In Hong Kong, hypertension affects over 30 % of adults, and heart failure prevalence is rising with an ageing population. Enalapril belongs to the blood‑pressure medication group and is prescribed when clinicians need a proven, long‑acting ACE inhibitor that can be taken once daily. The active compound is Enalapril, and the drug is available in generic form from multiple manufacturers. It is also sometimes employed off‑label for diabetic nephropathy and for prevention of cardiovascular events after myocardial infarction.

What is Enalapril?

Enalapril is a synthetic, orally administered ACE inhibitor that blocks the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor.

• Classification: ACE inhibitor, antihypertensive, heart‑failure therapy.
• Development: First synthesized by Merck & Co. in the 197s; the original brand name was Vasotec.
• Manufacturer: Original brand manufactured by Merck; numerous generic producers supply Enalapril worldwide.

Enalapril is the generic version of Vasotec, containing the same active compound Enalapril. Our online pharmacy provides this generic alternative as a cost‑effective treatment option.

How Enalapril Works

Enalapril is a prodrug that is converted by hepatic enzymes to its active form, enalaprilat. Enalaprilat binds to the active site of ACE, preventing the enzyme from producing angiotensin II. The reduction in angiotensin II leads to:

1. Vasodilation: Lowering systemic vascular resistance and arterial pressure.
2. Decreased aldosterone secretion: Reducing sodium and water retention, which further lessens blood volume.

The onset of blood‑pressure lowering occurs within 30 minutes after oral dosing, with a peak effect at 3–4 hours. The antihypertensive effect persists for 24 hours, permitting once‑daily dosing. Enalaprilat is eliminated primarily by the kidneys; the half‑life is approximately 11 hours in patients with normal renal function, extending in renal impairment.

Conditions Treated with Enalapril

• Essential (primary) hypertension: Reduces systolic and diastolic pressures, lowering the risk of stroke and coronary artery disease.
• Heart failure with reduced ejection fraction: Improves survival and reduces hospitalisation by decreasing afterload and neurohormonal activation.
• Post‑myocardial infarction: Lowers the likelihood of reinfarction and mortality when started early after the event.
• Diabetic nephropathy (microalbuminuria): Slows progression of kidney disease by reducing intraglomerular pressure.

In Hong Kong, hypertension is a leading public‑health challenge; the Hong Kong Centre for Health Protection estimates >2 million adults are untreated or under‑treated. Enalapril’s once‑daily dosing and proven mortality benefit make it a cornerstone therapy in the local guidelines.

Who is Enalapril For?

Enalapril is suitable for adult patients who:

• Have diagnosed hypertension (stage 1 or 2) and require an ACE inhibitor as first‑line or add‑on therapy.
• Exhibit left‑ventricular systolic dysfunction (ejection fraction ≤ 40 %) after a myocardial infarction or with chronic heart failure.
• Show early signs of diabetic kidney disease, indicated by albuminuria.

Clinical scenarios where Enalapril is particularly recommended include:

• Patients who prefer a single daily dose and have stable renal function.
• Individuals who cannot tolerate angiotensin II receptor blockers (ARBs) due to cost or adverse‑effect profile.

Enalapril may be inappropriate for:

• Patients with a history of angio‑edema related to ACE‑inhibitor therapy.
• Pregnant or lactating women (ACE inhibitors are contraindicated).
• Severe renal impairment (eGFR < 30 mL/min/1.73 m²) without dose adjustment; such patients require specialist assessment.

Risks, Side Effects, and Interactions

Common

• Dry cough: Occurs in up to 10 % of users; often resolves after dose reduction or switch to an ARB.
• Headache: Usually mild and transient.
• Dizziness or light‑headedness: Related to orthostatic hypotension, especially after the first dose.
• Fatigue: May improve over weeks as blood pressure stabilises.

Rare

• Taste disturbances (dysgeusia).
• Dermatologic reactions: Rash or pruritus, reported in < 1 % of patients.
• Elevated serum potassium (hyperkalaemia): More likely with concurrent potassium‑sparing diuretics or renal impairment.

Serious

• Angio‑edema: Swelling of lips, tongue, or airway; requires immediate medical attention.
• Severe hypotension: Particularly after initial dosing in volume‑depleted patients.
• Acute kidney injury: Risk increases with concomitant NSAIDs, diuretics, or in patients with pre‑existing renal disease.

Drug‑Drug Interactions

• Diuretics (especially thiazides): May potentiate the antihypertensive effect; monitor electrolytes.
• Potassium‑sparing agents (spironolactone, amiloride): Heighten hyperkalaemia risk.
• Non‑steroidal anti‑inflammatory drugs (NSAIDs): Can reduce renal perfusion and increase blood‑pressure variability.
• Lithium: ACE inhibition may raise lithium levels; close monitoring is advised.

Patients should disclose all medications, including over‑the‑counter products and herbal supplements, to their prescriber.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing for hypertension: 5 mg once daily, titrated to 10–40 mg based on response and tolerability.
• Heart‑failure dosing: Initiate at 2.5 mg once daily; typical maintenance 10–20 mg.
• Renal impairment: Reduce initial dose by 50 % when eGFR < 50 mL/min/1.73 m²; avoid if eGFR < 30 mL/min/1.73 m² without specialist guidance.

Missed dose: If a dose is forgotten, take it as soon as remembered unless it is close to the next scheduled dose; in that case, skip the missed dose and continue with the regular schedule. Do not double‑dose.

Overdose: Symptoms may include profound hypotension, dizziness, and fainting. Immediate medical attention is required. Treatment is symptomatic, often involving intravenous fluids and vasopressors; activated charcoal may be considered if ingestion is recent.

Practical precautions

• Take Enalapril with or without food; consistency aids adherence.
• Avoid excessive alcohol, which can potentiate hypotensive effects.
• Maintain adequate hydration, especially during hot weather or illness, to reduce orthostatic episodes.
