As a consequence, these drugs can increase the concentrations of co-administered metabolized drugs, and are subject to having their own concentrations increased by other CYP inhibitors. A recent study indicates that CYP3A4 undergoes dramatic conformational changes upon binding to ketoconazole or erythromycin with a differential but substantial (>80%) increase in the active site volume, providing a structural basis for ligand promiscuity of CYP3A4.

Many drug interactions are a result of inhibition or induction of cytochrome P450 enzymes (CYP450). The inhibition or induction of CYP3A4 by drugs often causes unfavorable and long-lasting drug-drug interactions and probably fatal toxicity, depending on many factors associated with the enzyme, drugs and the patients. Unfortunately, many CYP3A4 substrates have substantial toxicity, and some patients may develop severe toxicity when CYP3A4 inhibitors are taken concurrently. Phase I vs. Unlike metabolic inhibition, there is usually a delay before enzyme activity increases, depending on the half-life of the inducing drug.
