Klarytromycyna i Deksametazon: interakcja

• Avoid concomitant use of strong CYP3A4 inhibitors or inducers.

Avoid coadministration of strong CYP3A4 inhibitors or consider alternative medication that are not strong CYP3A4 inhibitors.

If concomitant use of strong CYP3A4 inhibitors cannot be avoided, closely monitor for adverse drug reactions.

( ‎7.2 ) 7.1 Effect of Other Drugs on HEMADY Strong CYP3A4 inhibitors Coadministration of strong and moderate CYP3A4 inhibitors increased dexamethasone exposure [see Clinical Pharmacology (‎ 12.3 )] , which may increase the risk of adverse reactions [see Warnings and Precautions (‎ 5 ) and Adverse Reactions (‎ 6 )] .

Miscellaneous Cytochrome P450 Inducers: Efavirenz Nevirapine Rifampicin Rifabutin Rifapentine Use With Caution Inducers of CYP3A enzymes, such as efavirenz, nevirapine, rifampicin, rifabutin, and rifapentine will increase the metabolism of clarithromycin, thus decreasing plasma concentrations of clarithromycin, while increasing those of 14-OH-clarithromycin.

Alternative antibacterial treatment should be considered when treating patients receiving inducers of CYP3A.

Since the microbiological activities of clarithromycin and 14-OH-clarithromycin are different for different bacteria, the intended therapeutic effect could be impaired during concomitant administration of clarithromycin and enzyme inducers.
