Biochem/physiol Actions

Dirithromycin is a macrolide antibiotic. It is a prodrug of erythromycylamine that has outstanding activity against Campylobacter. Dirithromycin is a group 3 agent with respect to its interaction with cytochrome P450 (CYP) isoform 3A4, as it interferes poorly with CYP3A4 in vitro and generally does not alter drug metabolism in vivo.

Packaging

1G

Preparation Note

When dissolving dirithromycin in organic solvents, first purge the solvent with inert gas.

To prepare in aqueous buffer, dirithromycin should first be dissolved in ethanol and then diluted with aqueous buffer. The solution is stable for one day.

Dirithromycin is soluble in ethanol at approximately 20 mg/mL, DMF at approximately 10 mg/mL, and DMSO at approximately 15 mg/mL.

Other Notes

Keep container tightly closed in a dry and well-ventilated place.
