6 . The sulfonamide pharmaceutical composition of claim 1 , wherein said pharmaceutical composition is injectable.
7 . A method to prepare the sulfonamide pharmaceutical composition of claim 1 , comprising the steps of:
1) Putting a prescription amount of sulfonamide compound, PEG-400, and 2-ethyl-1,3-hexanediol into a container, stirring slowly at 85° C.-95° C. to form a miscible solution, Solution A, for later use; 2) Putting a prescription amount of sebacic acid and 1,2-propanediol, into a separate container, stirring slowly at 85° C.-95° C. to form a miscible solution, Solution B, for later use; 3) Mixing Solution A and Solution B while maintaining the temperature at 85° C.-95° C., and stirring to obtain a homogenous solution for later use; 4) Putting a prescription amount of dimethyl sulfoxide and a small amount of anhydrous ethanol into a container, stirring and mixing well to obtain a homogenous solution, Solution C, for later use; 5) Cooling the mixture of Solution A and Solution B to 60° C., adding Solution C to the mixture, stirring and mixing well before cooling down to room temperature, adding the remaining amount of anhydrous ethanol and mixing well; 6) Filtering with 0.45 um microporous membrane, aliquoting into 5 ml ampoules and sealing the ampoules; and 7) Sterilizing at 121° C. for 30 minutes.
8 . A method to prepare the sulfonamide pharmaceutical composition of claim 1 from the following raw materials, comprising the steps of:
