Miconazole (commonly prescribed for oral thrush) is a CYP450 2C9 enzyme inhibitor. CYP3A4 inducers are drugs that increase the activity of CYP3A4. 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. Note: Many of these chemical inhibitors are not specific for an individual CYP enzyme. Studies have shown that it can be classified as a strong CYP3A inhibitor when a certain preparation is used (e.g., high dose, double strength) or as a moderate CYP3A inhibitor when another preparation is used (e.g., low dose, single strength).l The classification is based on studies conducted with intravenously administered conivaptan.m Diltiazem increased the AUC of certain sensitive CYP3A substrates (e.g., buspirone) more than 5-fold.

Cytochrome P450 (CYP450) enzymes can be inhibited or induced by some drugs, resulting in significant drug interactions that can cause unanticipated adverse reactions or therapeutic failures. OATP1B1/OATP1B3: (1) AUC fold-increase is 2 for at least one of clinical substrates in Table 5-1 with co-administration; and (2) in vitro inhibitor of OATPB1 and/or OATP1B3.
