title: Chronopharmacokinetics of rifampicin.
abstract: Chronopharmacokinetics of rifampicin was studied in four healthy adult male human volunteers after drug (2.0 g) ingestion at 6.00, 12.00, 18.00 and 24.00 hr. The absorption rate constant was found to be lower and the time to reach peak concentration was longer after drug administration at 24.00 hr than at other dosing times. A second peak was observed in all individual volunteers between 6-12 hr after drug dosing at 24.00 hr. This may be due to the influence of biliary rhythms on the disposition kinetics of rifampicin.
