Abstract

The invention discloses glimepiride hydrogel which comprises glimepiride, meglumine, azone, oleic acid, ethylparaben, EDTA-2Na, glycerol, carbomer, triethavolamine and purified water. The glimepiride hydrogel is prepared through the following steps: dissolving glimepiride and meglumine in purified water by heating to obtain a glimepiride cosolvent water solution; and adding azone, oleic acid, ethylparaben, EDTA-2Na and glycerol into the glimepiride cosolvent water solution in sequence, performing stirring uniformly, adding carbomer, performing swelling, adding triethanolamine, and performing stirring uniformly to obtain the glimepiride hydrogel. A prescription provided by the invention is scientific, the process is reasonable, and the prepared glimepiride hydrogel has the characteristics of uniform and exquisite texture, strong adhesive force, good coating performance, easiness in cleaning, good moisture retention, high stability and the like, has good skin permeability, good biocompatibility, a lasting drug effect and small toxic and side effects, is easy to control in dosage, and is suitable for mass diabetic patients (especially for type 2 diabetic patients) to use for a long time.

Description

technical field [0001] The invention relates to a combination preparation for external use, in particular to a glimepiride hydrogel and a preparation method thereof. Background technique [0002] The chemical name of Glimepiride is 1-[4-[2-(3-ethyl-4-methyl-2-oxo-3-pyrroline-1-carboxamido)-ethyl]- Benzenesulfonyl]-3-(trans-4-methylcyclohexyl)-urea is a third-generation sulfonylurea and an oral hypoglycemic agent that can be used in combination with insulin. β - Cells release insulin and inhibit the synthesis of hepatic glucose. Compared with other hypoglycemic drugs of the same class, it has the advantages of quick onset, strong effect, long duration and small dose. [0003] At present, the dosage forms of glimepiride on the market are mainly oral dosage forms such as tablets, dispersible tablets, dropping pills, and capsules. For example, CN103893143A discloses a glimepiride oral tablet, its components are: glimepiride 2%, antioxidant 0.01-0.03%, acid-causing agent 0.3-1....
