Summary

The pharmacokinetic interactions of ofloxacin (2×200 mg) and theophylline (3×200 mg) were investigated in 12 healthy volunteers over a period of two weeks. In the first week, theophylline was given over five days to reach a steady state. In the second week, the combination of theophylline and ofloxacin was applied. Cmax, tmax, AUC0–8, the serum elimination constant and serum half-life of theophylline were not changed when theophylline was given alone or in combination with ofloxacin. The kinetic parameters of ofloxacin were in accordance with data from the literature.

Zusammenfassung

Die pharmakokinetischen Interaktionen zwischen Ofloxacin (2×200 mg) und Theophyllin (3×200 mg) wurden bei 12 gesunden freiwilligen Probanden über einen Zeitraum von 12 Wochen erforscht. In der ersten Woche wurde Theophyllin fünf Tage lang allein gegeben, um den Steady State zu erreichen. In der zweiten Woche wurde Theophyllin in Kombination mit Ofloxacin verabreicht. In den Werten Cmax, tmax, AUC0–8, Serumeliminationskonstante und Serumhalbwertszeit von Theophyllin fanden sich keine Unterschiede bei alleiniger Gabe oder in Kombination mit Ofloxacin. Die kinetischen Parameter von Ofloxacin stimmten mit publizierten Daten überein.
