I-Letrozole (i-CAS 112809-51-5) yinxalenye yesizukulwana esitsha se-aromatase inhibitors ekhethiweyo kakhulu kwaye i-artificially synthesized benzotriazole derivative.I-Letrozole inqanda i-aromatase ekunciphiseni amanqanaba e-estrogen, ngaloo ndlela ikhusela i-estrogen ekukhuthazeni ukukhula kwe-tumor.Umsebenzi wayo we-vivo unamandla ngamaxesha angama-150-250 kunalowo wesizukulwana sokuqala i-aromatase inhibitor i-Amarante.Njengoko ikhetha kakhulu, ayiyi kuchaphazela i-glucocorticoid, i-mineralocorticoid kunye nemisebenzi ye-thyroid;nakwiidosi eziphezulu, aziyi kuba nemiphumo yokuthintela kwi-adrenal corticosteroid secretion, inika isalathisi esiphezulu sonyango.I-Letrozole ayinayo i-toxicity efihlakeleyo kuyo nayiphi na inkqubo yomzimba kunye nezitho ezijoliswe kuyo, ayinayo i-mutagenicity kunye nemiphumo ye-carcinogenic, ineempembelelo ezincinci ezinobuthi, inyamezeleke kakuhle, kwaye ineempembelelo ezinamandla ze-anticancer kunezinye i-aromatase inhibitors kunye neziyobisi ze-antiestrogen.I-Letrozole ifanelekile kwizigulane zomhlaza webele eziphucukileyo ze-postmenopausal ezingakhange ziphendule unyango lwe-estrogen-suppressing kunye nonyango lomhlaza webele kwangoko.Isetyenziselwa ukunyanga izigulane zasemva kokuyeka ukuya exesheni ezinomhlaza webele ophezulu kwaye isebenza njengonyango lodidi lwesibini ukulandela unyango lwe-antiestrogen olungaphumelelanga.
