Letrozole (CAS 112809-51-5) ndi gawo la m'badwo watsopano wa aromatase inhibitors omwe amasankha kwambiri ndipo ndi opangidwa mwaluso opangidwa ndi benzotriazole.Letrozole imalepheretsa aromatase kuti achepetse misinkhu ya estrogen, motero amalepheretsa estrogen kuti asalimbikitse kukula kwa chotupa.Ntchito yake mu vivo ndi mphamvu 150-250 kuposa ya m'badwo woyamba aromatase inhibitor Amarante.Chifukwa chosankha kwambiri, sichidzakhudza glucocorticoid, mineralocorticoid ndi ntchito za chithokomiro;ngakhale pa mlingo waukulu, sizikhala ndi zotsatira zolepheretsa adrenal corticosteroid secretion, zomwe zimapatsa chiwerengero chachikulu cha mankhwala.Letrozole ilibe poizoni wobisika ku machitidwe aliwonse a thupi ndi ziwalo zomwe zikuyang'aniridwa, alibe mutagenicity ndi carcinogenic zotsatira, ali ndi zotsatira zochepa zapoizoni, amalekerera bwino, ndipo ali ndi zotsatira zamphamvu za anticancer kuposa ena aromatase inhibitors ndi antiestrogen mankhwala.Letrozole ndi yoyenera kwa odwala khansa ya m'mawere apamwamba omwe sanayankhepo chithandizo cha estrogen-suppressing komanso chithandizo cha khansa ya m'mawere oyambirira.Amagwiritsidwa ntchito pochiza odwala omwe ali ndi khansa yapamwamba ya m'mawere ndipo amakhala ngati chithandizo chachiwiri kuti atsatire chithandizo cha antiestrogen chosapambana.
