title: Effect of renal function and dialysis on temocillin pharmacokinetics.
abstract: Temocillin pharmacokinetics in renal impairment were investigated following an intravenous bolus injection of 15 mg/kg. The 28 patients were divided into 5 groups of varying renal function, from normal to uraemic [including a group being treated with haemodialysis and a group on continuous ambulatory peritoneal dialysis (CAPD)]. The distribution of temocillin into the tissues was not affected by renal dysfunction. Uraemia as compared to normal renal function resulted in a 4.3-fold decrease in temocillin clearance and a 3.1-fold decrease in urinary recovery over 24 hours, as well as a 5- and 3.7-fold increase in the beta half-life and the area under the curve (AUC), respectively. Haemodialysis doubled the serum clearance and halved the beta half-life of temocillin in the uraemic subject, but CAPD over 24 hours eliminated only 8% of the temocillin dose, resulting in a minimal change in pharmacokinetics. Temocillin dosage adjustments in renal failure are proposed.
