Aromasin 25mg Tablet
Product Introduction
Aromasin 25mg Tablet contains Exemestane (25mg), a potent and irreversible steroidal aromatase inhibitor that has significantly advanced the treatment of hormone-receptor-positive breast cancer in postmenopausal women. Unlike non-steroidal aromatase inhibitors, Exemestane has a unique steroidal structure that allows it to permanently inactivate the aromatase enzyme, effectively reducing estrogen production throughout the body, which is crucial as many breast cancers rely on estrogen to fuel their growth.
Developed as a second-generation aromatase inhibitor, Aromasin offers a distinct clinical advantage with its "suicide inhibitor" mechanism that permanently binds to the aromatase enzyme. The 25mg tablet is the standard therapeutic dose, carefully determined to provide maximum efficacy while maintaining a manageable side effect profile. Typically prescribed for extended periods—often 5 years after tamoxifen therapy or as initial adjuvant therapy—Aromasin plays a vital role in reducing breast cancer recurrence risk.
Healthcare providers prescribe Aromasin after careful assessment of the patient's medical history, cancer characteristics (particularly hormone receptor status), menopausal status, and current health condition. Regular follow-up evaluations during treatment help monitor efficacy and identify any developing side effects. Aromasin is specifically indicated for postmenopausal women, as its mechanism of action would be ineffective in premenopausal patients without additional ovarian function suppression.
Clinical studies have demonstrated Aromasin's significant benefits, including improved disease-free survival and reduced risk of cancer recurrence and contralateral breast cancer. In early-stage breast cancer, it's often prescribed as part of extended adjuvant therapy after tamoxifen or as upfront adjuvant therapy. For advanced or metastatic breast cancer, Aromasin may be used after progression on other hormonal therapies. With its distinctive irreversible binding mechanism, Aromasin represents an important treatment option in the hormonal therapy arsenal against breast cancer, offering patients a therapy that effectively targets the hormonal drivers of their disease.

Benefits of Aromasin Tablet
- Irreversibly binds to aromatase enzyme, offering potentially more complete estrogen suppression
- Reduces risk of breast cancer recurrence in postmenopausal women
- Improves disease-free survival rates
- May be effective after progression on non-steroidal aromatase inhibitors
- Once-daily dosing improves treatment compliance
- Mild androgenic effects may positively impact bone health compared to other aromatase inhibitors
- Reduces risk of contralateral breast cancer
- Maintains quality of life with manageable side effect profile for many patients
- May have favorable impact on lipid profiles compared to some other aromatase inhibitors
How Aromasin Tablet Works (Mechanism of Action)
Exemestane in Aromasin works through a unique "suicide inhibition" mechanism. As a steroidal compound structurally related to androstenedione (the natural substrate of the aromatase enzyme), Exemestane is recognized by the aromatase enzyme and converted to an intermediate that irreversibly binds to the enzyme, permanently inactivating it.
In postmenopausal women, estrogen is primarily produced in peripheral tissues (fat, muscle, liver, and breast tissue itself) through the conversion of androgens to estrogens by the aromatase enzyme. By inactivating this enzyme, Aromasin significantly reduces circulating estrogen levels by approximately 85-95%, effectively "starving" estrogen-dependent breast cancer cells of the hormone they need for growth and proliferation.
Unlike non-steroidal aromatase inhibitors that bind reversibly to the enzyme, Exemestane's permanent binding means that estrogen production can only resume when new aromatase enzymes are synthesized. This mechanism results in more durable estrogen suppression, which may provide clinical advantages in certain patients. Additionally, Exemestane's steroidal structure gives it mild androgenic properties that may have different effects on lipid profiles and bone health compared to non-steroidal aromatase inhibitors.
