Pharmacokinetics of ciprofloxacin in subjects with varying degrees of renal function and undergoing hemodialysis or CAPD.

The pharmacokinetics of a single, oral dose of 750 mg of ciprofloxacin were studied in 35 subjects with various degrees of renal function (Group 1, Clcr > or = 80 ml/min; Group II, Clcr 50-79 ml/min; Group III, Clcr 10-49 ml/min) and on hemodialysis (HD) or continuous ambulatory peritoneal dialysis (CAPD). Blood, urine and CAPD dialysate samples were collected over a period of 48 hours after dosing. Data were fitted using non-linear, least squares regression. The mean Cmax was 3.4 +/- 1.0 mg/l and tmax was 2.3 +/- 0.9 hours. The mean AUC in Group I was 14.7 mg.h/l, Group II was 33.7 (p < 0.001), Group III 63.8 (p < 0.001), HD 57.9 (p < 0.0001) and CAPD 44.3 (p < 0.001). Half-life in Group I was 4.6 h, and was shorter than Group III (11.1 h, p < 0.001), HD (13.4 h, p < 0.001) and CAPD (8.9 h, p < 0.001). Total body clearance and renal clearance demonstrated significant differences also. The dialysis clearance in CAPD patients was 0.53 +/- 0.39 l/h. Peritoneal effluent concentrations varied from 0.6 mg/l during the first exchange, to a peak of 2.2 mg/l during the second, to 0.13 mg/l in the 48 hour (9th) exchange. Dosage adjustments of ciprofloxacin in the presence of renal insufficiency are indicated for subjects with a Clcr < 20 ml/min/1.73m2.[1]
