WebSep 1, 2008 · Because many other commonly used drugs are moderate-to-potent inhibitors of CYP3A4, it is not surprising that drug toxicity of CYP3A4 substrates due to inhibition of CYP3A4 is relatively common. CYP3A4 also is sensitive to enzyme induction, and a number of drugs are known to be CYP3A4 inducers. 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.
