Problems solved by technology

[0002] Dexamethasone acetate is a kind of adrenal cortex hormone drug. Its anti-inflammatory, anti-allergic and anti-shock effects are more significant than prednisone, but it is insoluble in water. Currently, dexamethasone acetate tablets in the veterinary drug market are mainly water-insoluble , the breeding mode has changed from free-range farming to intensive farming. Therefore, the water solubility requirements of drugs in the market are constantly increasing

Abstract

Water-soluble dexamethasone acetate tablets are prepared from raw materials in parts by weight as follows: 0.5-0.7 parts of dexamethasone acetate, 1-3 parts of PEG-6000, 80-90 parts of water-soluble starch, 1-5 parts of sucrose, 1-5 parts of gamma-cyclodextrin, 2-5 parts of sodium alginate and 2-5 parts of hydroxymethyl cellulose; preferably, the water-soluble dexamethasone acetate tablets are prepared from raw materials in parts by weight as follows: 0.6 parts of dexamethasone acetate, 2 parts of PEG-6000, 85 parts of water-soluble starch, 3.5 parts of sucrose, 3 parts of gamma-cyclodextrin, 3.5 parts of sodium alginate and 3.5 parts of hydroxymethyl cellulose. The water-soluble dexamethasone acetate tablets are simple to process, the equipment investment is low, insoluble raw materials are subjected to physicochemical treatment with a solid dispersion technology, and the water solubility of the dexamethasone acetate tablets is obviously improved on the premise that the chemical structure and the pharmacological action are unchanged, so that the product can meet water drinking use and adapt to intensive cultivation of the market.
