🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine is a potent and selective non-steroidal aromatase inhibitor. It works by binding reversibly to the aromatase enzyme, which is responsible for converting androgens (such as testosterone and androstenedione) into estrogens (such as estrone and estradiol). By inhibiting aromatase, this medicine significantly reduces circulating estrogen levels in postmenopausal women, where estrogen is primarily produced through peripheral conversion in adipose tissue and other sites. In breast cancer, many tumors are hormone receptor-positive and depend on estrogen for growth. By lowering estrogen, this medicine starves these cancer cells of their growth stimulus, leading to reduced tumor growth and improved survival. In fertility treatment, the reduction in estrogen feedback leads to increased secretion of follicle-stimulating hormone (FSH) from the pituitary, which stimulates ovarian follicles and induces ovulation.
Mechanism Steps
💡 How to Take ceolet 2.5mg tablet
Strength: Letrozole 2.5 mg immediate-release tablet.
Dosage Information
| Adult Dosage | The usual adult dose for breast cancer is 2.5 mg once daily, with or without food. For ovulation induction, the dose is typically 2.5 mg once daily for 5 days, starting on day 3 to 5 of the menstrual cycle. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. |
| Elderly Dosage | No dose adjustment is required for elderly patients based on age alone. However, elderly patients may be more sensitive to side effects; monitor closely. |
| Renal Impairment | No dose adjustment is needed for mild to moderate renal impairment. In severe renal impairment (creatinine clearance <10 mL/min), use with caution as letrozole has not been studied extensively. |
| Hepatic Impairment | In patients with mild to moderate hepatic impairment, no dose adjustment is needed. In severe hepatic impairment, dose reduction may be necessary; use with caution. |
| Maximum Daily Dose | The maximum recommended daily dose is 2.5 mg. |
