Carbamazepine affects metabolism of other drugs using which enzyme system?

Explanation:
Carbamazepine affects drug metabolism primarily by inducing hepatic cytochrome P450 enzymes, notably CYP3A4. By increasing the activity of these enzymes, it speeds up the metabolism of many drugs that rely on this pathway, lowering their blood levels and potentially reducing effectiveness. It can also auto-induce its own metabolism, causing dosing changes over time. Other enzymes listed don’t play the central role here: monoamine oxidase metabolizes neurotransmitters, alcohol dehydrogenase handles alcohol metabolism, and ATP synthase is part of energy production, not drug metabolism.
