Water-soluble film coated premix agent

Abstract

The invention relates to a water-soluble film coated premix agent, which comprises the following components: cellulose derivatives or acrylic acid derivatives, polyvinyl alcohol, povidone K30, polyethylene glycol 6000, glyceryl triacetate, talcpowder and water. According to the water-soluble film coated premix agent, a coated layer and medicinal tablets are combined firmly and closely, so that the tablets are uniform in coloring, and uniform in thickness and smooth; and the coated premix agent with different colors can be obtained by different ratios of titanium dioxide and a colorant, so that colorless and transparent coating, white coating and the colored coating can be obtained; and therefore, the appearance of medicines is improved. The polyvinyl alcohol is added into the water-soluble film coated premix agent, so the solid content of the film coated premix agent can be improved; and therefore, coating time is shortened.

Description

technical field

[0001] The invention relates to the technical field of medicines, in particular to a water-soluble film coating premix. Background technique

[0002] With the continuous improvement of the pharmaceutical level, the continuous application of new pharmaceutical excipients and new technologies, drug coating has undergone the evolution from sugar coating to film coating. Film coating is a coating technology developed in the early 1950s. The film coating process can be widely used in tablets, pills, and granules, especially for traditional Chinese medicine tablets that are easy to absorb moisture, crack, and mottle. its superiority. Because film coating has the advantages of easy operation, short coating time, less weight gain, cost saving, good stability, and good moisture resistance, it has gradually replaced sugar coating. The film coating technology used in the pharmaceutical industry is a production process in which a small amount of safe, non-toxic and sta...
