Carbamazepine induces which enzyme systems?

Explanation:
Carbamazepine is a strong inducer of drug-metabolizing enzymes in the liver, with the most consistent and clinically important effect being the induction of the cytochrome P450 enzyme CYP3A4. When CYP3A4 is increased, drugs that rely on this enzyme for metabolism are cleared faster, which can lower their plasma levels and reduce effectiveness unless dosing is adjusted. While some sources note that carbamazepine can influence other enzymes as well, the primary and most reliable induction is of CYP3A4. That’s why identifying CYP3A4 induction as the main action best explains the drug–drug interaction profile of carbamazepine.
