🔬 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 (cytochrome P450 19A1), which is responsible for converting androgens such as testosterone and androstenedione into estrogens like estradiol and estrone. By inhibiting aromatase, this medicine significantly reduces circulating estrogen levels in postmenopausal women, where estrogen is primarily produced through peripheral aromatization of androgens. In hormone-sensitive breast cancer, this reduction in estrogen deprives tumor cells of the growth stimulus they need, thereby slowing or stopping tumor growth. In fertility treatment, the reduction in estrogen feedback leads to increased secretion of follicle-stimulating hormone (FSH) from the pituitary, which stimulates ovarian follicles to mature and release eggs.
Mechanism Steps

Strength: This medicine is available as an immediate-release tablet for oral administration. The strength is not specified in the provided information. Common strengths include 2.5 mg. Always check the label for the exact strength prescribed.
Dosage Information
| Adult Dosage | The usual adult dose of this medicine for breast cancer is 2.5 mg taken orally once daily, with or without food. For ovulation induction, the dose is typically 2.5 mg to 5 mg once daily for 5 days, starting on day 3 to 5 of the menstrual cycle. The dose must be individualized by a qualified clinician based on the indication, patient's age, weight, renal and hepatic function, and response to treatment. Do not adjust the dose without medical advice. |
| 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 susceptible to side effects such as bone loss and cardiovascular events. Regular monitoring is advised. |
| Renal Impairment | No dose adjustment is required for patients with mild to moderate renal impairment (creatinine clearance 10-80 mL/min). Caution is advised in severe renal impairment (creatinine clearance <10 mL/min) due to limited data. |
| Hepatic Impairment | No dose adjustment is required for patients with mild to moderate hepatic impairment. In severe hepatic impairment (Child-Pugh class C), letrozole should be used with caution and dose reduction may be considered based on clinical judgment. |
| Maximum Daily Dose | The maximum recommended daily dose is 2.5 mg for breast cancer. For ovulation induction, doses up to 7.5 mg daily have been used in clinical trials, but the maximum should not exceed 7.5 mg daily. Always follow your doctor's prescription. |
