Strong and moderate CYP3A4 inducers are drugs that decrease the AUC of sensitive substrates of a given pathway where CYP3A4 is involved by ≥80 percent and ≥50 to <80 percent, respectively. [83] [123] Weak inducers decrease the AUC by ≥20 to <50 percent. [123] The inducers of CYP3A4 are the following substances.

These chemicals inhibit key drug metabolizing enzymes, such as cytochrome P450 3A4 (CYP3A4). CYP3A4 is a metabolizing enzyme for almost 50% of drugs, and is found in the liver and small intestinal epithelial cells. [19]
Cytochromes P450 (P450s or CYPs) are a superfamily of enzymes containing heme as a cofactor that mostly, but not exclusively, function as monooxygenases. [1] However, they are not omnipresent; for example, they have not been found in Escherichia coli. [2]

Many substrates for CYP3A4 are drugs with a narrow therapeutic index, such as amiodarone [10] or carbamazepine. [11] Because these drugs are metabolized by CYP3A4, the mean plasma levels of these drugs may increase because of enzyme inhibition or decrease because of enzyme induction.
CYP3A4 inducers can counteract the inhibiting effects of ritonavir and lead to drastically reduced levels of "boosted" drugs, increasing the risk of developing drug resistance. Other CYP3A4 inhibitors may have an additive effect with ritonavir, causing increased drug levels. [9]
