Kinetics of intravenously administered carnitine in haemodialysed children.
The pharmacokinetics of low-dose bolus L-carnitine (5 mg kg-1 body wt) in five haemodialysed children were investigated. Kinetic variables were obtained by applying a two-compartment open model. The elimination half-life was very short, 2.43 +/- 0.35 h, despite the reduced plasma clearance of 41.2 +/- 5.7 ml min-1, compared with healthy adults. The apparent volume of distribution, 0.27 +/- 0.07 1 kg-1 body wt, corresponds well to the size of the extracellular space. The kinetic behaviour of intravenously supplied carnitine may assist in future evaluations of the therapeutic application of this drug in uraemic children.
