[The effect of verapamil on peritoneal dialysis efficiency in a clinical study].

Authors investigated influence of intraperitoneal verapamil on standard peritoneal dialysis efficiency. 18 peritoneal dialyses were performed in 4 patients. Verapamil was used in doses 5 and 10 mg per exchange of peritoneal fluid without a significant influence on ultrafiltration, sodium sieving index, urea and creatinine clearances. At the start of the study all patients had normal peritoneum evaluated with peritoneal scintigraphy using sulphide colloid, glucose equilibrium curve and D/P for creatinine.
