Cytochrome Enzymes and Glycoproteins: What You need to Know
Cytochrome P450 (CYP) enzymes play a crucial role in metabolizing over 70% of clinical drugs, primarily in the liver. P-Glycoproteins (PGP) help pump foreign substances out of cells. Drug interactions with these proteins can lead to toxicity or reduced efficacy. Clinically significant drugs may induce or inhibit these proteins, requiring careful monitoring for interactions.
