Lestace (Lisinopril)

Lisinopril is used to manage conditions within the renin‑angiotensin‑aldosterone system that affect blood pressure and cardiac function.

• Hypertension: reduces elevated blood pressure, decreasing risk of stroke and kidney damage.
• Heart failure: improves symptoms and survival by decreasing cardiac workload.
• Post‑myocardial infarction: lowers the chance of subsequent cardiovascular events and aids cardiac remodeling.

• Lisinopril blocks the angiotensin‑converting enzyme (ACE), preventing the conversion of angiotensin I to the potent vasoconstrictor angiotensin II. This inhibition reduces vasoconstriction, lowers aldosterone secretion, and promotes vasodilation, leading to decreased peripheral resistance and blood pressure. By diminishing the renin‑angiotensin cascade, lisinopril helps to protect renal function and reduces cardiac remodeling over time.

Lisinopril may cause a range of adverse reactions, from mild to serious.

Common Side Effects

• Cough: persistent dry cough.
• Dizziness: especially when standing quickly.
• Headache: mild to moderate intensity.
• Fatigue: general feeling of tiredness.
• Hypotension: low blood pressure, particularly after first dose.
• Taste disturbance: altered taste perception.

Serious or Rare Side Effects

• Angioedema: swelling of face, lips, tongue, or throat.
• Severe hypotension: marked drop in blood pressure causing faintness.
• Renal impairment: worsening kidney function.
• Hyperkalemia: elevated blood potassium levels.
• Hepatic dysfunction: abnormal liver enzymes.
• Anaphylactic reaction: rare severe allergic response.

When prescribing lisinopril, clinicians should observe several safety considerations.

• Monitor blood pressure: ensure adequate control and avoid excessive drops.
• Assess renal function: check serum creatinine before and during therapy.
• Check serum potassium: hyperkalemia risk, especially with concomitant drugs.
• Avoid in patients with prior angioedema: risk of recurrence.
• Use caution during pregnancy: limited data, potential fetal risk.
• Store at room temperature: keep in the original packaging, protect from moisture.

Lisinopril can interact with other medicines, altering its efficacy or safety profile.

Major Interactions (Avoid)

• Aliskiren: combined renin‑angiotensin blockade increases risk of renal dysfunction.
• Potassium‑sparing diuretics (e.g., spironolactone): may cause dangerous hyperkalemia.
• NSAIDs (high‑dose): can reduce antihypertensive effect and impair kidney function.
• Lithium: increased lithium levels and toxicity risk.
• Dual ACE inhibitor/ARB therapy: heightened risk of hypotension and renal injury.

Moderate Interactions (Monitor Closely)

• Thiazide diuretics: may enhance hypotensive effect.
• Other antihypertensives: additive blood pressure lowering.
• Diabetic medications: monitor blood glucose as ACE inhibitors can affect insulin sensitivity.
• Antacids containing aluminum or magnesium: may affect absorption if taken simultaneously.
• Rifampin: may reduce lisinopril plasma concentrations.
