The effect of celiprolol on glomerular filtration rate and renal blood flow in patients with chronic renal impairment and healthy volunteers.

A double-blind, placebo controlled study investigated the effects of celiprolol, 200 mg daily for 7 days, on glomerular filtration rate (GFR) and estimated renal blood flow (ERBF) in eight healthy volunteers and eight patients with chronic renal insufficiency. In healthy volunteers the mean difference in GFR was 4.8 ml min-1 (95% CI -8.2 to 17.7 ml min-1) and the mean difference in ERBF was 49.8 ml min-1 (95% CI -47.5 to 147 ml min-1) after celiprolol. In patients with chronic renal insufficiency the mean difference in GFR was -2.1 ml min-1 (95% CI -64.6 to 65.8 ml min-1). The study had sufficient power to detect a 15% change in GFR for normals and 10% for patients, and for ERBF, changes of 14% and 23% were detectable. Celiprolol at a dose of 200 mg daily for 7 days can be used in patients with chronic renal insufficiency without adversely affecting GFR or ERBF.
