Abstract

A dispersing tablet of tamoxifen citrate is prepared from tamoxifen citrate, disintegrant, filler, lubricant and alcohol through sieving by 100 meshes, proportionally mixing, wet granulating, drying, sieving by 18-24 meshes, adding lubricant, and tabletting. It can be used for treating mastadenoma, melanocarcinoma, etc.

Description

Technical field: [0001] The invention relates to the technical field of medicine, specifically tamoxifen citrate dispersible tablet and its preparation method and application. Background technique: [0002] Tamoxifen citrate, the chemical name is (Z)-N,N-dimethyl-2-[4-(1,2-diphenyl-1-butenyl)phenoxy]-ethylamine Citrate, synthesized in 1964. Tamoxifen is a steroid that is structurally similar to estrogen. Pharmacological research data show that tamoxifen can compete with estradiol for estrogen receptors in the cytoplasm, form stable complexes with estrogen receptors, and transport them in the nucleus. However, this complex does not stimulate RNA and protein synthesis, but depletes estrogen receptors in the cytoplasm, thereby antagonizing the effects of estrogen. The anti-breast cancer effect of this product mainly relies on its anti-estrogen effect to stop the growth of estrogen-dependent cancer cells. Its curative effect is directly proportional to the estrogen receptor ...
