title: How frequently should anti-inflammatory drugs be given? A study with indoprofen.
abstract: Indoprofen, despite its relatively short plasma half-life, was just as effective given twice daily as when the same daily total was given in four divided doses. There was a trend in favour of the twice daily regime for changes in morning pain and the duration of morning stiffness. Preferences were equally divided between the two regimes and efficacy was the usual reason for patients preferring one or other. Side-effects were no more frequent with the twice daily regime. Pharmacokinetics are no substitute for clinical experiment in planning the dosage regime of a non-steroidal anti-inflammatory drug.
