Example Embodiment

[0016] A method for preparing a moisture-proof film coating agent for traditional Chinese medicine tablets consists of the following steps:

[0017] ⑴ Put the vinylpyrrolidone-vinyl acetate copolymer, 5-15 centipoise hypromellose, polyethylene glycol 6000, iron oxide, titanium dioxide and talc into a high-speed mixer at a rotation speed of 2700 rpm. The mixing time is 0.5 to 3 minutes; the speed of the high-speed mixer is 2700 rpm, and the mixing time is 0.5 to 3 minutes.

[0018] ⑵After pouring Tween 80 evenly on the materials in the high-speed mixer, mix at 2700 rpm for 0.5 to 3 minutes to make the finished product of Chinese medicine tablet moisture-proof film coating agent.

Example Embodiment

[0019] Example 1

[0020] A preparation method of a moisture-proof film coating agent for traditional Chinese medicine tablets, comprising:

[0021] (1) Weigh 20 parts of vinylpyrrolidone-vinyl acetate copolymer, 30 parts of 5-15 centipoise hypromellose, 600020 parts of polyethylene glycol, 803 parts of Tween, and iron oxide according to the mass parts ratio. 10 parts, 17 parts talcum powder;

[0022] (2) Pour the vinyl pyrrolidone-vinyl acetate copolymer, 5-15 centipoise hypromellose, polyethylene glycol 6000, iron oxide, titanium dioxide and talc into a high-speed mixer at a rotation speed of 2700 R / min mixing for 2 minutes;

[0023] (3) Pour Tween 80 evenly on the materials in the high-speed mixer, and mix at 2700 rpm for 15 minutes to form a moisture-proof film coating agent for traditional Chinese medicine tablets.

Example Embodiment

[0024] Example 2

[0025] (1) Weigh 50 parts of vinylpyrrolidone-vinyl acetate copolymer, 10 parts of hypromellose 5-15 centipoise, 600010 parts of polyethylene glycol, 803 parts of Tween, and 10 parts of iron oxide according to the mass parts ratio. Parts and 17 parts of talcum powder;

[0026] (2) Put 5-15 centipoise of hypromellose, polyethylene glycol 6000, iron oxide, titanium dioxide and talc into a high-speed mixer, and mix at 2700 rpm for 2 minutes;

[0027] (3) Pour Tween 80 evenly on the materials in the high-speed mixer, and mix at a speed of 2700 rpm for 15 minutes to form a traditional Chinese medicine tablet film coating agent.

[0028] Using conventional methods, the moisture-proof film coating agent of a traditional Chinese medicine tablet of Example 1 and Example 2 is made into a solution, and sprayed on the surface of the traditional Chinese medicine core to form a moisture-proof film coating tablet. Then the moisture resistance test is carried out: the moisture abs...

Abstract

The invention relates to a moistureproof film coating agent for traditional Chinese medicine tablets and a preparation method thereof. The technical characteristic is that the film coating agent comprises the following components according to mass proportion: 20-50 portions of vinyl pyrrolidone-vinyl acetic ester copolymer, 10-30 portions of 5-15 centipoise hydroxypropyl methylcellulose, 10-20 portions of polyethylene glycol 6000, 1-5 portions of tween 80, 0-25 portions of ferric oxide, 0-20 portions of titanium dioxide and 0.1-30 portions of talc powder. The preparation method comprises the following steps: (1) the vinyl pyrrolidone-vinyl acetic ester copolymer, the 5-15 centipoise hydroxypropyl methylcellulose, the polyethylene glycol 6000, the ferric oxide, the titanium dioxide and the talc powder are put in a high-speed mixer for mixing; and (2) the tween 80 is evenly poured to and mixed with the materials in the high-speed mixer to prepare the finished products of moistureproof film coating agent for traditional Chinese medicine tablets. Various macromolecule film-forming materials are adopted to prepare the film coating agent, thus the moistureproof performance of traditional Chinese medicine tablets is enhanced, the problem of moisture absorption of traditional Chinese medicine is thoroughly resolved and the application range of film coating agent is enlarged.

Description

technical field [0001] The invention belongs to the field of pharmaceutical excipients, in particular to a traditional Chinese medicine tablet moisture-proof film coating agent and a preparation method thereof. Background technique [0002] Film coating agent is a kind of material for coating oral tablets, usually composed of film forming agent, plasticizer, auxiliary additive and coloring agent, when used, water or a mixture of water and ethanol is used as a solvent, sprayed on The surface of the drug core can form a smooth and uniform film coat, so that the drug core can avoid the erosion of light, oxygen, and moisture, and can beautify the appearance, improve the taste, and cover the odor. Compared with sugar coating, the film coating agent can save the coating operation time, and the performance of the tablet after coating is more stable. Although the film coating agents on the market have good mechanical properties, their moisture-proof effect on Chinese medicine table...
