Clinical Application:
1). Treatment of breast cancer.
2). Prevention of breast cancer.
3). Anti-tumor and anti-multidrug resistance.
By reducing membrane negotiability and enhancing rigidity of inter-cell binding site, Tamoxifen citrate can reduce concentration and activity of cancer metastasis promoter and various activating enzymes, so as to inhibit or hinder growth and metastasis of cancer cell. In addition, it can promote cells surrounding tumor focus to secrete a negative growth factor - transforming growth factor TGF- G, inhibiting multiply indefinitely of cancer cells; inhibiting oxidative damage of DNA bases which is caused by hydrogen peroxide generated from human neutrophils. So except for breast cancer, it is good for treatment and prevention of other malignant neoplasms, and is used for treatment of brain tumors, liver cancer, prostate cancer, etc. In addition, Tamoxifen citrate can reduce release effect of membrane P170 glycoprotein through reducing membrane negotiability, improving intracellular effective concentration of cytotoxic drug and reducing drug resistance 4).Heart protection.
