A stabilized microcapsules coated cysteamine hydrochloride and its preparation method

The present invention relates to a stable microcapsule coated cysteamine hydrochloride and its preparation method, which is made mainly by the mass of starting material was prepared as follows: cysteamine hydrochloride 20 to 55 parts, 15 to 35 parts of corn starch , sodium carboxymethyl cellulose, 0.1 to 10 parts, 1 to 10 parts of sodium alginate, 0.1 to 10 parts of ethyl cellulose, 10 to 15 parts by [beta] -cyclodextrin, from 10 to 50 parts carnauba wax. The present invention provides a stable microcapsule coated cysteamine hydrochloride and its preparation process, an effective solution of cysteamine hydrochloride susceptible to oxidation, inadequate hygroscopic, so as to protect the cysteamine hydrochloride purpose; the same time, limits the maximum degree of cysteamine hydrochloride released in the stomach to prevent gastric ulcer, and sufficiently released in the intestine, thus more effectively utilized animals, promote animal growth, having good application prospect.
