🔬 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 the final step in estrogen biosynthesis. By inhibiting aromatase, it reduces the conversion of androgens (such as testosterone and androstenedione) to estrogens (estrone and estradiol). This leads to a significant decrease in circulating estrogen levels, which is beneficial in hormone receptor-positive breast cancers that require estrogen for growth.
Mechanism Steps
💡 How to Take armotraz tablet
Strength: 1 mg immediate-release tablet
Dosage Information
| Adult Dosage | The standard adult dose is 1 mg taken orally once daily. It can be taken with or without food. For early breast cancer, treatment is usually continued for 5 years. For advanced breast cancer, treatment continues until disease progression or unacceptable toxicity. 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, close monitoring for side effects is advised due to potential comorbidities. |
| Renal Impairment | No dose adjustment is needed for mild to moderate renal impairment. In severe renal impairment (creatinine clearance <30 mL/min), use with caution and monitor closely. |
| Hepatic Impairment | No dose adjustment is needed for mild to moderate hepatic impairment. In severe hepatic impairment, use with caution as anastrozole clearance may be reduced. |
| Maximum Daily Dose | 1 mg |
