title: Comparison of the effects of penbutolol and propranolol on glomerular filtration rate in hypertensive patients with impaired renal function.
abstract: 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.
