Pharmacological properties

Letrozole is a non-steroidal aromatase inhibitor (estrogen biosynthesis inhibitor) with anti-tumour activity.

In cases where the growth of tumour tissue depends on the presence of oestrogens, elimination of the stimulating effect of oestrogens is a prerequisite for inhibition of tumour growth. In postmenopausal women, estrogens are mainly formed by the enzyme aromatase, which converts androgens synthesised in the adrenal glands (mainly androstendione and testosterone) into estrone (E1) and estradiol (E2). Therefore, by specifically inhibiting the aromatase enzyme, inhibition of estrogen biosynthesis in peripheral tissues and tumour tissue can be achieved.
