Letrozole 2.5mg per ml x 30ml
Letrozole is an orally active, nonsteroidal, selective aromatase inhibitor and hence an antiestrogen which may prevent the formation of estrogens. Therefore, it may reduce or prevent the unwanted and feminizing effects that include male breast development (gynecomastia), water retention, and belly fat.
How Letrozole works:
Estrogens are produced by the conversion of androgens through the activity of the aromatase enzyme. Letrozole blocks production of estrogens in this way by reversible binding to the heme of its cytochrome P450 unit. Specifically, Letrozole does not reduce production of corticosteroids. It inhibits the liver enzyme CYP2A6, and to a lesser extent CYP2C19, in vitro, but no relevant interactions with drugs like cimetidine and warfarin have been observed.
In contrast, the antiestrogenic action of Tamoxifen, the major medical therapy prior to the arrival of aromatase inhibitors, is due to its interfering with the estrogen receptor, rather than inhibiting estrogen production.
Letrozole’s effects on serum estrogen level control are perhaps the strongest and most effective of the three major aromatase inhibitors. Letrozole has exhibited at least 98% reduction or more of serum Estrogen levels in studies. It can be effective at inhibiting the aromatase enzyme and thereby reducing estrogen levels. Administration of this compound to post-menopausal females, and/or utilized when other first-line treatments for breast cancer does not work.
- reduce bloating due to excess water retention
- prevent the formation of gynecomastia related breast tissue
- lowers the levels of the female sex hormone oestrogen in the body
