Pharmacokinetics of enalapril in normal subjects and patients with renal impairment

Abstract

The pharmacokinetics of enalaprilat were studied after administration of single and multiple doses of enalapril maleate to people with normal and impaired renal function. Renal impairment was associated with higher serum concentrations of enalaprilat, longer times to peak concentrations, slower decline of serum concentrations and with reduced urinary elimination. Urinary elimination of enalaprilat was closely related to renal function. In patients with severe renal impairment (GFR values below 30 ml min-1 1.73 m-2) significantly smaller doses of enalapril maleate will be required than in patients with normal or less severely impaired renal function.
