Lisinopril Dosing and Management for Hypertension and Heart Failure

Introduction to Lisinopril Dosing

The European Society of Cardiology recommends starting lisinopril at 2.5 mg daily for all heart failure patients 2, 3
Titrate the dose upward at intervals of not less than 2 weeks based on blood pressure response 1

Higher doses (32.5-35 mg daily) significantly reduce mortality and hospitalization compared to low doses (2.5-5 mg daily) in the ATLAS trial 2, 3
The target dose for heart failure patients is 30-35 mg once daily, as tolerated 2, 3, 4

In hemodynamically stable patients within 24 hours of MI, give 5 mg orally, then 5 mg after 24 hours, 10 mg after 48 hours, then 10 mg once daily 5

Check serum potassium and creatinine after 5-7 days of starting therapy, and recheck every 5-7 days during titration until potassium values are stable 2, 3
Monitor blood pressure, renal function, and electrolytes 1-2 weeks after each dose increment, and check at 3 months, then every 6 months thereafter 2, 3, 4
An increase in creatinine up to 50% above baseline, or to 3 mg/dL, whichever is greater, is acceptable 1, 4
Avoid NSAIDs and COX-2 inhibitors, as they can worsen renal function and reduce ACE inhibitor efficacy 2, 3
Avoid potassium-sparing diuretics during initiation unless specifically needed for persistent hypokalemia 2, 3

Many clinicians fail to titrate to target doses - the ATLAS trial clearly demonstrated that higher doses (30-35 mg daily) reduce hospitalizations by 24% and the combined endpoint of death or hospitalization by 12% compared to low doses 2, 3
ACE inhibitor-induced cough rarely requires discontinuation, and only switch to an angiotensin receptor blocker if cough is proven to be ACE inhibitor-related through withdrawal and rechallenge 1
