Cytochrome P450
CYP450定義
A superfamily of liver enzymes responsible for metabolizing approximately 75% of all drugs. Key isoforms include CYP3A4 (metabolizes ~50% of drugs), CYP2D6, CYP2C9, and CYP1A2. Drugs that inhibit or induce these enzymes can significantly alter the metabolism of other medications.
例
Grapefruit juice inhibits CYP3A4, which can dramatically increase blood levels of statins like simvastatin, raising the risk of muscle damage.
