Storage method
this The product should be sealed and stored in a cool place.
Synthesis method
By Phthalic anhydride and chlorobenzene are added, nitrated and reduced to obtain phthalic anhydride (3-Amino– 4-Chlorobenzoyl) benzoic acid, then diazotization, displacement, chlorosulfonation, and finally cyclization and amination.
Purpose
Applicable For cardiac, renal, hepatic and other edema diseases, combined use with antihypertensive drugs can increase the efficacy. The preparation is a tablet.
