Comparison of the Effects of Penbutolol and Propranolol on Glomerular Filtration Rate in Hypertensive Patients with Impaired Renal Function
Overview
Affiliations
Penbutolol and propranolol were administered orally in a dosage of 40 mg once daily and 80 mg twice daily, respectively to 12 patients with hypertension and impaired renal function. Both drugs caused a significant decrease in mean arterial pressure and heart rate. Serum creatinine concentration increased significantly by 10% during therapy with propranolol without concomitant decrease in creatinine clearance. No such effect was seen with penbutolol. GFR measured with [125I]-iothalamate showed no significant changes with both drugs.
