Abstract

The invention relates to a coating material for complex tablets and a preparation method thereof. The coating material is composed of following raw materials by weight: 3 parts to 8 parts of acrylic resin solution, 12 parts to 20 parts of red iron oxide injectable suspension, 1 part to 5 parts of glycerol, 1 part to 5 parts of talcum powder and 60 parts to 80 parts of purified water. The complex tablet thin membrane coated tablet made of the coating material is even in tablet surface color and strong in coating membrane adhesion. Accelerated tests and long term experiments show that the coating material is good in humidity resistance, can effectively prevent volatile element borneol from sublimating and dissolving out, and guarantees quality stability of products in an efficacy period.

Description

technical field [0001] The invention relates to a coating material for compound salvia miltiorrhiza tablets, and also relates to a preparation method of the coating material, which belongs to the technical field of medicine preparation. Background technique [0002] Compound Danshen Tablets are composed of Danshen, Panax notoginseng and Borneol. The product contains Danshen extract and Borneol. Among them, the amount of Danshen extract is relatively large, plain tablets are easy to absorb moisture, and Borneol has a certain volatility, which can only be obtained by coating. Effectively prevent tablet moisture absorption and borneol precipitation. Sugar coating is commonly used. In recent years, film coating has been widely used as one of the major achievements in the development of preparation technology. The existing film coating materials are difficult to ensure that the medicine does not absorb moisture and the borneol does not separate out. Contents of the invention ...
