1. What is Aromasin? Aromasin effects
Aromasin medicine contains the main active ingredient is Exemestane and other excipients. The drug works as follows:
Exemestane is a member of a new class of drugs used for second-line treatment in postmenopausal women with advanced breast cancer long after treatment with tamoxifen has failed. Exemestane has a particularly favorable mechanism of action compared with other drugs. Exemestane binds irreversibly to the oestrogen-producing enzyme, preventing oestrogen production, until a new enzyme is formed. That, in turn, causes the tumor to starve for estrogen and stop growing. Exemestane is indicated for the first-line treatment of hormone receptor-positive advanced breast cancer in postmenopausal women, either physiologically or under the influence of other causes. Exemestane is indicated for the second-line treatment of advanced breast cancer in physiologically postmenopausal women or postmenopausal women after monotherapy with anti-estrogen therapy. . Exemestane is also indicated as a third-line treatment in the treatment of advanced breast cancer in women following combination hormone therapy.

5. Aromasin drug interactions
Drugs that stimulate the CYP3A4 isoenzyme (eg, rifampicin, phenytoin, deferasirox) decrease Exemestane concentrations. The dose of Aromasin should be increased to 50 mg/day in patients receiving these drugs concomitantly. Hypericum perforatum (St. John's grass) reduces the concentration of the active ingredient Exemestane. Do not use the drugs Cimicifuga racemosa (thang ma), Angelica sinensis (dong quai) for people with estrogen-dependent breast cancer. Do not use in combination with estrogen-containing drugs because these drugs reduce the effect of Exemestane.
