39 results about "Anhydrous Dextrose" patented technology

The anhydrous form of D-glucose, a natural monosaccharide and carbohydrate. Dextrose serves to replenish lost nutrients and electrolytes. The agent provides metabolic energy and is the primary ingredient in oral rehydration salts (ORS) and is used in intravenous (IV) fluids to provide nutrients to patients under intensive care who are unable to receive them by the oral route. Solutions containing dextrose restore blood glucose levels and provide calories and may aid in minimizing liver glycogen depletion and exerts a protein-sparing action. Dextrose anhydrous also plays a role in the production of proteins and in lipid metabolism.

Preparation method of stress oral liquid

This invention belongs to the field of veterinary drug technology, specifically a method for preparing a stress-relieving oral liquid. The specific steps of this method are as follows: weighing the Chinese herbal medicine slices, soaking and pre-treatment, heating and extraction, filtering the extract, vacuum concentration, and preparing the oral liquid. This method uses a low-temperature vacuum concentration process to prepare a Gardenia jasminoides extract after the Chinese herbal medicine extraction, avoiding the destruction of the active ingredients by high temperatures and maximizing the retention of the effective active substances of Coptis chinensis, Scutellaria baicalensis, and Gardenia jasminoides. In the subsequent compounding process, pharmaceutical-grade anhydrous glucose and sodium salicylate are selected as excipients to form a stable and homogeneous system with the compound small molecule peptides and the Gardenia jasminoides extract. This system is free of easily separated, precipitated, or turbid components, effectively tolerating the high temperature and humidity environment of farms, the bumpy rides of long-distance transportation, and the requirements of long-term storage, preventing rapid degradation of the active ingredients of the Chinese herbal medicine, and ensuring the stable efficacy of the oral liquid.

The tooth-benefiting xylitol tablet candy is prepared from the following raw materials: xylitol, modified sodium alginate, HPMCP-genipin, microcrystalline cellulose, colloidal silicon dioxide and magnesium stearate. After the HPMCP-genipin enters the enteric cavity, the shell is dissolved, the L-glutamine and the anhydrous dextrose maintain and stabilize the osmotic pressure of intestinal cells, the genipin of the inner core and the primary amine group on the molecular chain of the modified sodium alginate are covalently crosslinked to form a gel network to wrap the xylitol, and meanwhile, the gel network absorbs water to form a local isotonic environment. A gel network wrapping xylitol enters a large intestine and is dissolved under the action of coliform bacteria, and galactooligosaccharide selectively stimulates the growth of bacteria methanogens capable of utilizing hydrogen, so that the total volume and partial pressure of gas in the intestinal tract are reduced. The microcrystalline cellulose improves the viscous component of the modified sodium alginate, and the colloidal silicon dioxide reduces the shearing and extrusion on the HPMCP-genipin in the tabletting process.
