What Experts Say

Letrozole belongs to the non steroidal aromatase inhibitor class. It works by blocking the enzyme aromatase, which converts androgens into estrogen in peripheral tissues. This action lowers circulating estrogen levels significantly in postmenopausal women, which slows the growth of estrogen dependent breast cancer cells.

In women with anovulatory infertility, the drop in estrogen triggers the hypothalamus to release more gonadotropin releasing hormone. This raises follicle stimulating hormone output from the pituitary gland and encourages ovarian follicles to mature and release an egg. Clinical guidelines now favor letrozole over older ovulation induction agents for many PCOS patients because of its favorable pregnancy outcomes.

Pharmacokinetic studies show letrozole is well absorbed orally and has a long elimination half life, allowing once daily dosing. Liver enzymes metabolize the drug, so patients with hepatic impairment need dose caution. Experts stress that response should be monitored with hormone levels and ultrasound rather than fixed duration alone.
