Cyp 3a4 Inducers

Get to Know an Enzyme: CYP3A4

CYP3A4 Inducers CYP3A4 inducers are drugs that increase the activity of CYP3A4. Note that the CYP3A4 enzyme is particularly suscep-tible to enzyme inducers, and marked reductions in the plasma concentrations of CYP3A4 substrates may occur. For example, a patient taking the potent CYP3A4 inducer rifampin may have a
