PROCESS FOR STABILIZING PREPARATION OF L-GLUTAMINE AND AZULENE

摘要

The stabilization method of a composite antiulcer drug of a L-glutamine and a water-soluble azulene is characterized by adding 0.04˜1.5wt% of a clathrate compound i.e. beta-cyclodextrin, alpha-cyclodextrin, gamma-cyclodextrin, maltosyl cyclodextrin, glucocyclodextrin or methyl cyclodextrin and a filler i.e. carboxymethyl cellulose. The stabilization method prevents an oxidation and a photolysis of the drug, and improves a prolonging property of the drug.
