Abstract

The invention discloses a pharmaceutical composition and application thereof, and the pharmaceutical composition is composed of 1, 6-fructose diphosphate (FDP) or a pharmaceutically acceptable salt thereof, and nicotinamide mononucleotide NMN / nicotinamide adenine dinucleotide NAD + or a pharmaceutically acceptable salt thereof. The invention also discloses application of the compound in preparation of medicines for preventing and / or treating primary dysmenorrhea and infertility. The invention discloses an action mechanism of FDP and NMN / NAD < + > combined administration in treating a mouse primary dysmenorrhea model, and finds that the FDP and NMN / NAD < + > combined administration has a better curative effect than FDP or NMN / NAD < + > independent administration, and can obviously reduce the writhing reaction frequency of a female mouse, increase the incubation period of the writhing reaction, reduce the gene expression level of COX-2 and PGF2alpha in uterine tissues, increase the gene expression level of PGE2, and improve the mouse primary dysmenorrhea treatment effect. Infiltration of inflammatory cells is reduced, and uterine tissue edema and inflammatory pathology degree are improved; in addition, combined administration of FDP and NMN / NAD + can significantly increase the pregnancy rate of female mice compared with independent administration of FDP or NMN / NAD +.
