[0029] The present invention also provides a kind of preparation method of described Citicoline Sodium Injection, comprising the following steps:
[0030] (1) Dissolve citicoline sodium, disodium cytidine triphosphate and ginsenoside Rg1 in 50-60 vol% water for injection, then adjust the pH to 5.7-6.3 with a pH regulator, and then cool down to 3-5 ℃, and pass CO 2 20~60min, obtain medicinal liquid A;
[0031] (2) adding medicinal charcoal to the medicinal solution A, stirring and adsorbing for 15-45 min, decarbonizing and filtering, then adding glutathione, a stabilizer, an isotonicity agent and the remaining 40-50 vol% water for injection to obtain liquid B;
[0032] (3) filtering medicinal liquid B with a microporous membrane of 0.2~0.5 μm, then feeding nitrogen to nitrogen saturation, then filling and sealing in nitrogen flow to obtain semi-finished product of Citicoline Sodium Injection;
[0033] (4) The semi-finished product of Citicoline Sodium Injection is sterilize...
