Letrozole 2.5mg is an oral medication that inhibits the aromatase enzyme, which is responsible for converting androgens into estrogen in postmenopausal women. By reducing estrogen levels in the body, Letrozole helps to slow down or halt the growth of hormone receptor-positive breast tumors that rely on estrogen for their development.
- Breast Cancer Treatment: Letrozole is highly effective in the treatment of hormone receptor-positive breast cancer in postmenopausal women. By suppressing estrogen production, it can help prevent the recurrence of breast cancer, shrink existing tumors, and slow down the progression of the disease.
- Hormone Regulation: Letrozole plays a crucial role in regulating hormone levels in women. It specifically targets estrogen production and helps to maintain a low estrogen environment, which is beneficial in certain medical conditions such as breast cancer and conditions where excessive estrogen production may be problematic.
- Increased Fertility: Letrozole is sometimes used off-label as a fertility treatment for women with ovulation-related infertility. By suppressing estrogen production, it can stimulate the release of follicle-stimulating hormone (FSH) from the pituitary gland, leading to the development and release of eggs from the ovaries.
- Precise Dosage Control: Letrozole is available in a standardized dosage of 2.5mg, which allows for accurate and consistent administration. This dosage is typically taken once daily, ensuring a reliable intake of the medication for the prescribed treatment duration.
