Hazardous Substances Data：: 112809-51-5(Hazardous Substances Data)

Use：: Letrozole, 4,4'-(1H-1,2,4-triazol-1-ylmethylene)dibenzonitrile (Femara), is used for most of thesame indications as anastrozole. It reduces concentrations ofestrogens by 75% to 95%, with maximal suppressionachieved within 2 to 3 days. Letrozole is specific for aromataseinhibition, with no additional effects on adrenal corticoidbiosynthesis. CYPs 3A4 and 2A6 are involved in themetabolism of letrozole to the major carbinol metabolite,which is inactive. The loss of the triazole ring, which is involvedin coordination of the heme iron, would explain theloss of activity. Letrozole strongly inhibits CYP2A6 invitro, with moderate inhibition of CYP2C19. The effect ofthis in vitro inhibition on the pharmacokinetics of coadministereddrugs is unknown. Tamoxifen reduces the levels ofletrozole significantly if they are used together, so combinationtreatment with these agents is not recommended.
