Istopril

Enalapril, the active ingredient in Istopril, is an angiotensin-converting enzyme (ACE) inhibitor presented as an oral tablet for oral use. It belongs to the antihypertensive therapeutic class and is indicated for the management of high blood pressure, chronic heart failure, and post‑myocardial infarction ventricular remodeling in adult patients.

GNH USA supplies Istopril as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, providing consistent product quality, regulatory compliance and reliable supply chains for global healthcare providers.

Istopril (enalapril) acts on the renin‑angiotensin‑aldosterone system to control cardiovascular conditions.

Hypertension: lowers systolic and diastolic blood pressure, reducing risk of stroke and heart attack. Chronic heart failure: improves symptoms and survival by decreasing cardiac afterload. Asymptomatic left ventricular dysfunction: slows progression to symptomatic heart failure. Post‑myocardial infarction ventricular remodeling: limits adverse remodeling and supports cardiac function.

Adverse reactions may vary in frequency and severity.

Common Side Effects: - Persistent dry cough - Dizziness or light‑headedness - Headache - Fatigue - Nausea - Taste disturbance

Serious or Rare Side Effects: - Angioedema (swelling of face, lips, tongue) - Severe hypotension - Acute renal impairment - Hyperkalemia - Neutropenia or leukopenia - Hepatic dysfunction

Patients should be evaluated for specific risk factors before initiating therapy.

Monitor blood pressure: ensure adequate control without excessive hypotension. Assess renal function: check serum creatinine and eGFR periodically. Check serum potassium: avoid hyperkalemia, especially with potassium‑sparing agents. Avoid use in pregnancy: classified as Category D due to fetal toxicity. Use caution in aortic stenosis: may precipitate hypotension. Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Enalapril may interact with several drug classes, requiring clinical attention.

Major Interactions (Avoid): - Aliskiren in diabetic patients: increased risk of renal dysfunction and hyperkalemia. - Lithium: enalapril can raise lithium levels, risking toxicity. - Potassium‑sparing diuretics or supplements: may cause dangerous hyperkalemia.

Moderate Interactions (Monitor Closely): - Loop or thiazide diuretics: may enhance hypotensive effect. - NSAIDs (e.g., ibuprofen): can reduce antihypertensive efficacy and impair renal function.
