The disposition of a single oral dose of diltiazem hydrochloride was studied in six male patients treated by continuous ambulatory peritoneal dialysis. Peak concentrations were obtained 2 to 4 hours postdose. The mean absorption rate constant was 0.94 +/- 0.21 (sd) hr-1, and the mean elimination half-life was 3.09 +/- 1.16 hr. Serum levels of deacetyldiltiazem, a metabolite of diltiazem, were always below 10 ng/mL. The amounts of diltiazem and deacetyldiltiazem eliminated in dialysate over 24 hours represent less than 0.1% of the administered dose. The pharmacokinetic parameters of diltiazem determined in these patients did not differ from those determined in healthy volunteers and in patients suffering from end-stage renal disease.

D007408	Intestinal Absorption	Uptake of substances through the lining of the INTESTINES.	Absorption, Intestinal
D007676	Kidney Failure, Chronic	The end-stage of CHRONIC RENAL INSUFFICIENCY. It is characterized by the severe irreversible kidney damage (as measured by the level of PROTEINURIA) and the reduction in GLOMERULAR FILTRATION RATE to less than 15 ml per min (Kidney Foundation: Kidney Disease Outcome Quality Initiative, 2002). These patients generally require HEMODIALYSIS or KIDNEY TRANSPLANTATION.
