Biochem/physiol Actions

Letrozol ist ein nicht-steroidaler Aromatase-Inhibitor der dritten Generation. Es ist ein kompetitiver Inhibitor des Aromatase Enzymsystems und verhindert so die Umwandlung von Androgenen zu Östrogenen. Letrozol hemmt Aromatase durch kompetitive Bindung an das Häm der Cytochrom-P450-Untereinheit des Enzyms, was zu einer Abnahme der Östrogen-Biosynthese in allen Geweben führt.

Letrozol ist ein nicht-steroidaler Aromatase-Inhibitor.
