Abstract

The invention discloses a preparation method for preparation containing glucosamine and an application thereof. The preparation is characterized in that the major component is one or the combination of more of the glucosamine, glucosamine hydrochloride, glucosamine sulfate sodium chloride double salt or potassium chloride double salt, and chondroitin sulfate. The preparation method is simple, convenient and time-saving to operate and is easy for large industrialized production.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and particularly relates to a preparation method and application of a preparation containing glucosamine. Background technique [0002] Amino dextran is a natural sugar derived from chitin, which is the main component of the cartilage matrix. By changing its side chain structure, it is easier to combine with water in the articular cartilage to maintain the lubrication of the joint cavity and buffer pressure. It has a certain protective effect on damaged chondrocytes and can be artificially synthesized. Currently, glucosamine, glucosamine hydrochloride, glucosamine sulfate sodium chloride double salt or potassium chloride double salt are commonly used. Glucosamine is one of the smallest units that make up polyglucosamine, and it forms polyglucosamine with uronic acid, including chondroitin sulfate, keratan sulfate, dermatan sulfate and hyaluronic acid. [0003] Anti-inflammatory drugs c...
