tamoxifen citrate (nolvadex ) 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.
mechanism of action
tct has cis-trans isomers, whose cis isomer shows a weak estrogenic effect, while the trans isomer has an anti-estrogenic effect. when early application of tamoxifen or existence of low concentration, it binds to the estrogen receptor (er) in cytoplasm, showing a weak estrogenic effect. after tct entering into cell nucleus, it can inhibit transcription and synthesis of nuclear er, generating a lasting anti-estrogen effect. the study found that many new features of tct were related to the mechanism of action which was beyond its competitive estrogen receptors - membrane regulating mechanisms. tct as the membrane modifier, can reduce cell circulation. on this basis, tct can also serve as an antioxidant to protect cell membranes and human ldl from happening oxidative damage.

the quality control process:
1) producing
a)each operator must do self-inspection of producs and make the corresponding inspection records.
b)full-time inspectors through check the operator self-inspection, and review and sign in the corresponding record. full-time inspection is responsible for inspection of finished product, and make the finished product incoming inspection records.
2) inspection
random sample, sample pretreatment, measuring and data processing.
3) before selling
test result can be provided before selling.only good quality goods will be into stock.
third-party detection institution is allowed if you are not satisfied with test results.
