Specification

It is a macrolide antibiotic that has an antimicrobial spectrum similar to or slightly wider than that of penicillin. Erythromycin estolate (CAS NO.3521-62-8) inhibits the cytochrome P450 system, particularly the CYP3A4 isozyme, which can cause it to affect the metabolism of many different drugs. It is not recommended when using clindamycin containing products, even topical products such as duac or benzaclin. In general, the simultaneous use two different erythromycin derivatives should be avoided as drugs in this macrolide family share a common mechanism of action.
