The present invention is directed to a pharmaceutical composition comprising a pharmaceutically acceptable carrier and a ω-(arylsulfonyl)alkylnitrile compound, or a pharmaceutically acceptable salt thereof. The present invention is also directed to a method for treating inflammation, inflammatory-related disorders, or pain, by administering an ω-(arylsulfonyl)alkylnitrile compound or a pharmaceutically acceptable salt or solvate thereof to a subject in need thereof.

The invention discloses an aripiprazole drug co-crystal and a preparation method thereof. Using aripiprazole as an active pharmaceutical ingredient and resveratrol as a precursor, the aripiprazole and white Veratrol co-crystals. The preparation method is as follows: equimolar aripiprazole and resveratrol are put into a mortar for grinding, ketone or alkyl nitrile solvent is added before grinding, manually ground for 30 minutes, and vacuum-dried at 40-60 DEG C to obtain aripiprazole. azole drug co-crystals. The powder dissolution experiment of aripiprazole and resveratrol showed that the dissolution rate of aripiprazole slowed down in both the acetate buffer solution of pH=4.0 and the phosphate buffer solution of pH=6.8, showing a potential sustained release effect. Therefore, by preparing the aripiprazole co-crystal into an intramuscular injection, it may be possible to achieve a long-term treatment of schizophrenia and reduce the effect of muscle stimulation.

The invention relates to a flame retardant anti-bacterial composite modifier used in the fiber field and a preparation method thereof. The active components of the flame retardant anti-bacterial modifier are alkyl phosphate and alkyl guanidine; and the preparation method of the flame retardant anti-bacterial composite modifier comprises the following steps of: (1) preparing alkyl tetrol phosphoric acid ester; and (2) taking alkyl tetrol phosphate ester B, alkyl guanidine C and p-benzoic acid alkyl nitrile D which have the equal amount of substance, adding concentrated sulfuric acid and dicyclohexylcarbodiimide / N, N'-diisopropyl carbodiimide (DCC / DIC) as catalysts, wherein the mass ratio of the concentrated sulfuric acid to the alkyl tetrol phosphate ester B is 1:2-4, the mass ratio of DCC / DIC to the alkyl guanidine C is 1:2-5, rising the temperature to 70 to 200 DEG C, after reacting for 3-10h, cooling, filtering and drying to obtain the solid composite modifier E. The flame retardant anti-bacterial composite modifier has the advantages of having the flame retardant anti-bacterial performance, good thermal stability, being capable of meeting the high temperature processing requirement and being not easy to degrade; and products machined and prepared by using the composite modifier are not easy to oxidize and change color; and the flame retardant anti-bacterial composite modifier is widely applied.
