Description
Technical field
The invention belongs to pharmaceutical technology field, in particular to a kind of method of granulating of mecobalamin dispersible tables.
Background technique
Methylamines drug is used for peripheral nerve disease, due to a lack of megaloblastic anemia caused by vitamin B12 etc.
Treatment.Compared with other vitamin B12 class drugs, Mecobalamin transitivity in nervous system is good, can promote nucleic acid, albumen and rouge
The metabolism of fat.It is pharmacologically the synthesis by promoting nerve cell nucleic acid and protein and neural myelin, to repair
The peripheral nerve being damaged.Clinically, methylamines drug is to the peripheral nerves disease such as diabetes nerve obstacle, polyneuritis
Disease especially has positive effect to numb, pain and paralysis, is the active drug of current such disease of clinical treatment, and secondary
It acts on minimum.In addition, some researches show that, Mecobalamin be effective treatment parkinsonism, Alzheimer syndrome, muscular atrophy and
Neurasthenic potential drug.
In existing mecobalamin dispersible tables, every contains Mecobalamin only 0.5mg, therefore is necessary to ensure that in the actual production process
The mixture homogeneity of product.The pelletization of existing mecobalamin dispersible tables is generally prepared in such a way that equivalent is progressively increased.
This mode is more traditional, needs repeatedly weighing and multiple hybrid manipulation to realize, production process is cumbersome, and production efficiency is lower.
If needing directly prepare using equipment the mixing of raw material, then Mecobalamin raw material can go out not in such a way that equivalent is progressively increased
The phenomenon that now reuniting not can guarantee the quality of final products to influence the homogeneity of product.
