Lisinopril
Lisinopril is an ACE inhibitor used to treat high blood pressure (hypertension), heart failure, and to improve survival after a heart attack. It works by relaxing blood vessels and reducing the workload on the heart.
Uses & Indications
- Treatment of high blood pressure (hypertension)
- Management of heart failure
- Kidney protection in patients with diabetes and protein in urine
- Improving survival and heart function after a heart attack
Common Side Effects
- Dry, persistent cough (very common)
- Dizziness or lightheadedness, especially when standing
- Elevated potassium levels (hyperkalaemia)
- Angioedema (swelling of face, lips, throat — rare but serious)
- Fatigue and headache
Drug Interactions
- Potassium supplements and potassium-sparing diuretics — hyperkalaemia risk
- NSAIDs (ibuprofen, aspirin) — reduced blood-pressure-lowering effect
- Lithium — lisinopril can increase lithium toxicity
- Diuretics — enhanced blood-pressure-lowering effect; risk of hypotension
Dosage Information
Typical starting dose for hypertension is 5–10 mg once daily. Maintenance doses range from 10–40 mg once daily. Kidney function and potassium must be monitored regularly.
