Drug Interactions
No interaction studies have been performed with Cetraxal Plus. However, due to negligible plasma levels observed after application in the ear (see Pharmacology: Pharmacokinetics under Actions), it is unlikely that ciprofloxacin or fluocinolone acetonide may show clinically meaningful systemic interaction with other drugs.
The systemic administration of some quinolones has been shown to enhance the effects of the oral anticoagulant, warfarin, and its derivatives, and has been associated with transient elevations in serum creatinine in patients receiving cyclosporine concomitantly.
Oral administration of ciprofloxacin has been shown to inhibit cytochrome P450 CYP1A2 and CYP3A4 isozymes, and alter the metabolism of methylxanthine compounds (caffeine, theophylline). Following topical otic administration of Cetraxal Plus, ciprofloxacin plasma concentrations are low, and it is unlikely that an interaction involving P450 metabolism with concomitant medications would result in clinically relevant changes in plasma levels of methylxanthine compounds.
It is recommended not to use other ear preparations concomitantly. If more than one medicine needs to be administered by this route, it is advised to administer them apart.
