Abstract

The invention relates to the technical field of pharmaceutical preparations, in particular to a pharmaceutical composition containing mecobalamin and a preparation method thereof. The pharmaceutical composition containing mecobalamin is composed of, by mass percentage, 0.01-1% of methylcobalamin, 1%-10% of a stabilizer, 40-95% of a diluent, 0-20% of a disintegrant, and 0.1-10% of a lubricant. The preparation method consists of: premixing mecobalamine and part of the diluents, then mixing the pre-mixture with the stabilizer, the diluent and the disintegrant to obtain mixed powder, mixing the mixed powder with the lubricant for a certain period of time to obtain mixed raw material powder, and subjecting the mixed raw material powder to direct tabletting and coating. The method provided by the invention adopts a dry granulation process, involves fewer steps, avoids the influence of moisture and heat to the main drug, further improves the quality of mecobalamin tablets, lowers the cost, and is beneficial to industrial production.

Description

technical field [0001] The technical field of pharmaceutical preparations of the present invention particularly relates to a pharmaceutical composition containing methylcobalamin and a preparation method thereof. Background technique [0002] With the development of society and the continuous improvement of the living standard of our people, the incidence of diabetes is gradually increasing. Peripheral neuropathy is one of the most common serious complications of diabetes, and the incidence rate can reach about 80%. Diabetic peripheral neuropathy will cause limb numbness in patients, and in severe cases, limb ulcers, muscle atrophy and severe pain will occur, and even necrosis of limbs will occur, resulting in disability. [0003] Methylcobalamin is a drug for the treatment of peripheral neuropathy and belongs to vitamin B 12 class, alias methyl vitamin B 12 , it exists in blood and spinal fluid, and repairs damaged peripheral nerves by promoting the synthesis of nucleic ...
