Abstract

The invention discloses a tenofovir alafenamide fumarate raw material medicine and a production process thereof. The tenofovir alafenamide fumarate raw material medicine includes anhydrous tenofovir,triphenyl phosphite, 4-dimethylaminopyridine, triethylamine, acetonitrile, ethyl acetate, methanol, concentrated hydrochloric acid, thionyl chloride, toluene, dichloromethane, L-alanine isopropyl ester hydrochloride, potassium hydrogencarbonate, fumaric acid and isopropanol. Production raw material excipients for the tenofovir alafenamide fumarate raw material medicine include lactose monohydrate,microcrystalline cellulose, croscarmellose sodium and magnesium stearate. The new manufacturing raw materials and the production raw material excipients are selected, so that the anti-hepatitis B effect of the medicine is more excellent, mass production can be performed through the novel production method, and the anti-hepatitis B effect is strengthened to some extent.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a raw material drug of tenofovir alafenamide fumarate and a production process thereof. Background technique [0002] Now our country is still a big country with hepatitis B, and there are many patients, and there is no way to cure hepatitis B at present. For patients, there is an urgent need for antiviral drugs with better efficacy and fewer side effects. At present, the hepatitis B drugs on the market are more or less drug-resistant, and the needs of patients for better treatment are far from being met. [0003] Hepatitis B brings not only physical pain, but also psychological pain to patients, because discrimination against hepatitis B patients is common in society, which will have a great impact on patients' making friends, life, study, and employment. Moreover, the treatment cost of hepatitis B patients is also a great social burden and family burden. Hepatitis B is still ...
