The invention discloses a temperature-sensitive non-steroid anti-inflammatory medicine solid dispersed agent and a rapidly dissolving tablet, and a preparation method thereof, and belongs to the fieldof medicine dosage form. The temperature-sensitive non-steroid anti-inflammatory medicine solid dispersed agent contains a non-steroid anti-inflammatory medicine and a temperature-sensitive carrier at a mass ratio of 1: (1-10). According to the preparation method, anti-solvent method is adopted for co-deposition of the non-steroid anti-inflammatory medicine and the temperature-sensitive carrier,and separation freeze drying is adopted for preparation. The interaction effect of the non-steroid anti-inflammatory medicine and the temperature-sensitive carrier is high, the temperature-sensitive non-steroid anti-inflammatory medicine solid dispersed agent is excellent in stability; after entering into the body and contact with digestive juice, under hydration effect, temperature sensitive change of the temperature-sensitive carrier is caused, system phase separation is caused, and rapid medicine release is achieved; and in addition, after adjusting of the temperature-sensitive non-steroidanti-inflammatory medicine solid dispersed agent with an accessory material, micro nano grade solid dispersion particles can be obtained, system fluidity and compressibility are improved, solid dispersed agent direct powder tabletting is realized. The temperature-sensitive non-steroid anti-inflammatory medicine solid dispersed agent possesses oral administration quick effect achieving effect, andis capable of increasing the relative bioavailability of non-steroid anti-inflammatory medicines.
