Take, for example, Plavix, which is used to prevent heart attacks (and other cardiovascular events). It is inactive when absorbed, but our metabolism has an enzyme that activates it.

WebInduction of cytochrome P450 enzymes is associated with an increased prevalence of clinical drug-drug interactions. Cyprotex’s Cytochrome P450 induction assay identifies the potential of test compounds to induce CYP1A2, CYP2B6 or CYP3A4 in cultured human hepatocytes by evaluating mRNA levels and/or catalytic activity. WebIn cardiovascular medicine, prodrugs have been successful. Older prodrugs such as angiotensin-converting enzyme inhi-bitors (ACEi) are considered cornerstones in the management of hypertension. ACE inhibitors are dicarboxyl ester prodrugs converted to their active -rilat form by liver esterase (such as enalapril and enalaprilat).
