title: Pharmacokinetics of imipenem/cilastatin in neutropenic patients with haematological malignancies.
abstract: The pharmacokinetics of imipenem/cilastatin were studied in febrile neutropenic patients with haematological malignancies. The peak plasma concentrations (36.4 +/- 4.96 mg/l), plasma half-life (60 min), volume of distribution (0.28 +/- 0.02 l/kg) and plasma clearance (3.23 +/- 0.38 ml/min/kg) were comparable with those in normal healthy volunteers suggesting that the drug handling is not appreciably altered in this group of patients. The administration of 12.5 mg/kg (max 1 g), 6-hourly achieved levels that were up to 3.5 times MICs of most relevant bacteria. The drug therefore has a potential use as empirical monotherapy in febrile neutropenic patients.
