Abstract

The invention provides citicoline sodium tablets which are medicinal preparations for treating sequela of a nervous system caused by a craniocerebral injury or a cerebrovascular accident, and a preparation method thereof. Every 1,000 tablets comprise 100.0 to 300.0g of citicoline sodium, 20.0 to 70.0g of starch, 50.0 to 160.0g of microcrystalline cellulose, 0.6 to 3g of hydroxypropyl methyl cellulose, 1.7 to 5.5g of magnesium stearate, 0 to 10g of sodium starch glycolate and 0 to 6.0g of pregelatinized starch. The preparation method of the citicoline sodium tablets mainly comprises the steps of sieving, weighing, proportioning, premixing, preparing a soft material, preparing wet granules, drying, granulating, mixing, tabletting, performing aluminum-plastic-aluminum packaging and outer packaging and the like. The tablets prepared by the method have the advantages of high yield, low cost, accurate divided dose, relatively stable medicinal physicochemical property and longer storage period and are convenient to carry and use.

Description

technical field [0001] The invention relates to a medicine and a preparation method thereof, in particular to citicoline sodium tablets and a preparation method thereof. Background technique [0002] Citicoline Sodium (Citicoline Sodium), its molecular formula is C 14 h 25 N 4 NaO 11 P 2 , is the monosodium salt of choline cytidine nucleoside diphosphate, is a nucleoside derivative, and the dry product contains not less than 98% of citicoline sodium. Citicoline sodium can promote brain substance metabolism and improve cerebral circulation by reducing cerebrovascular resistance and increasing cerebral blood flow. It can also enhance the function of the ascending reticular activation system of the brain stem, enhance the function of the vertebral system, and improve motor paralysis, so it has a certain effect on promoting the recovery of brain function and waking up. After injection of citicoline sodium injection, it can quickly enter the blood, and part of it enters the...
