Erythromycin is metabolized by enzymes of the cytochrome P450 system, in particular, by isozymes of the CYP3A superfamily. The activity of the CYP3A enzymes can be induced or inhibited by certain drugs (e.g., dexamethasone), which can cause it to affect the metabolism of many different drugs, including erythromycin. If other CYP3A substrates — drugs that are broken down by CYP3A — such as simvastatin (Zocor), lovastatin (Mevacor), or atorvastatin (Lipitor)—ar… WebDec 16, 2013 · Erythromycin is a selective inhibitor of CYP 3A enzyme (Murray, Reference Murray 1992), resulting in decreased metabolism of clozapine with increased serum concentration, increased somnolence, difficulty in coordination and tonic-clonic seizure (Funderburg et al.
