Background:
N-desmethyl Diltiazem is an active metabolite of the calcium channel inhibitor diltiazem.1It is formed from diltiazem by the cytochrome P450 (CYP) isoforms CYP3A4, CYP3A5, and CYP3A7.2N-desmethyl Diltiazem binds to isolated rat cerebral cortex homogenates (IC50= 323 nM) and inhibits spontaneous contractions in isolated rat portal veins (IC50= 489 nM).1It has been found as a contaminant in fresh water.3
