Lisinopril Dosing for Hypertension
For adults with hypertension, start lisinopril at 10 mg once daily and titrate to a target dose of 20-40 mg once daily based on blood pressure response. 1
Starting Dose
The FDA-approved initial dose is 10 mg once daily for most adults with hypertension 1. However, specific clinical scenarios require dose adjustment:
- 5 mg once daily if the patient is already taking diuretics 1
- 2.5-5 mg once daily for patients with heart failure 2, 3, 4, 5
- 5 mg once daily for elderly patients or those with renal impairment (creatinine clearance 10-30 mL/min) 1, 6, 7
- 2.5 mg once daily for patients with creatinine clearance <10 mL/min or on hemodialysis 1
Titration Schedule
Double the dose at 2-week intervals until blood pressure control is achieved or the maximum dose is reached 3, 8. Evidence shows that 50% of the maximum blood pressure-lowering effect occurs within 1 week of starting therapy 9, but full assessment should wait at least 2 weeks to allow for complete drug effect.
The usual maintenance dose range is 20-40 mg once daily 1. While doses up to 80 mg have been used, they do not appear to provide greater efficacy 1.
Target Doses from Clinical Trials
Multiple heart failure guidelines consistently recommend:
For hypertension specifically, the 2007 KDOQI guidelines recommend:
- Starting dose: 10 mg daily
- Goal dose: 20-40 mg daily 10
Monitoring Requirements
Check blood pressure, serum creatinine, and potassium within 1-2 weeks after initiation or dose changes 4. An expected creatinine increase up to 50% above baseline (or up to 3 mg/dL, whichever is greater) is acceptable and does not require discontinuation 8.
Common Pitfalls to Avoid
- Don't stop at subtherapeutic doses: Most patients in surveillance studies responded to 10-20 mg daily 11, but clinical trials used higher target doses (20-40 mg) to achieve cardiovascular benefits
- Don't rush titration: While BP effects begin within 1 week 9, wait at least 2 weeks between dose adjustments to assess full response
- Don't automatically discontinue for mild creatinine elevation: Up to 30% decline in eGFR with ACE inhibitors is expected and associated with long-term kidney protection 12
- Don't use twice-daily dosing routinely: Despite manufacturer labeling suggesting twice-daily dosing if once-daily is insufficient, real-world evidence shows no benefit of twice-daily administration 13, though one small study suggested modest additional systolic BP reduction with twice-daily dosing 14
Special Populations
Elderly patients: Start at 5 mg once daily if not on diuretics; most require 20-40 mg for adequate control 15, 6
Renal impairment: Dose reduction is mandatory based on creatinine clearance, but lisinopril remains effective and safe in this population 7
Pediatric patients ≥6 years: Start at 0.07 mg/kg once daily (maximum 5 mg), titrate to maximum 0.61 mg/kg once daily (maximum 40 mg) 1
