title: [The clinical pharmacokinetics of allopurinol. 2. Allopurinol/oxypurinol pharmacokinetics following allopurinol in single doses and multiple application].
abstract: In a pharmacokinetic study with 6 healthy volunteers the parameters for allopurinol and oxipurinol were compared following a single dose of allopurinol and multiple application of the drug. Pharmacokinetic data for allopurinol and oxipurinol are different after single doses and under steady state conditions. The oxipurinol half-life of 17 +/- 5.1 h is prolonged under steady state conditions to 19.7 +/- 5.8 h. Based on the results of this study and on data from different authors the range of 17-21 h is discussed as the most frequent oxipurinol half-life.
