Note: Index inducers predictably induce metabolism via a given pathway and are commonly used in prospective clinical DDI studies. About 347 SNPs have been identified in the CYP3A4 gene ( CYP3A4*1A : wild-type), 25 of which are of clinical relevance. Although this class has more than 50 enzymes, six of them metabolize 90 percent of drugs, with the two most significant enzymes being CYP3A4 and CYP2D6. 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. Some drugs, such as clarithromycin, itraconazole, and ketoconazole, are particularly potent inhibitors of CYP3A4; patients on these drugs may have markedly reduced CYP3A4 activity.
