Aromasin 25mg, manufactured by Nakon Medical, is a potent steroidal aromatase inhibitor designed to regulate estrogen levels in the body. Here are the key details about Aromasin:

1. Purpose:
   • Breast Cancer Treatment: Aromasin is primarily used to manage certain types of breast cancer in postmenopausal women.
   • Early Breast Cancer: It targets early breast cancer that has not spread beyond the breast.
   • Advanced Breast Cancer: Aromasin is effective against advanced breast cancer that has metastasized to other parts of the body.
   • After Tamoxifen: Sometimes, Aromasin is prescribed after a period of tamoxifen treatment (usually 2 or 3 years) or if tamoxifen is ineffective.
2. Mechanism of Action:
   • Aromasin lowers estrogen levels in postmenopausal women.
   • It inhibits the growth of estrogen-dependent breast tumors by blocking estrogen production.
3. Warnings and Precautions:
   • Allergy: Do not use Aromasin if you are allergic to exemestane.
   • Pregnancy: Avoid Aromasin during pregnancy as it can harm the unborn baby.
   • Liver or Kidney Disease: Inform your doctor if you have liver or kidney issues.
   • Bone Health: Aromasin may decrease bone mineral density, potentially increasing the risk of osteoporosis.
   • Fertility: While Aromasin affects fertility, continue using birth control if you are not past menopause.

   • The treatment duration may extend up to 5 years.
