The invention discloses a tigorazan
amorphous solid dispersion, a tigorazan-containing tablet core, a tigorazan tablet and a preparation process of the tigorazan
amorphous solid dispersion. The invention specifically discloses a tigorasan
solid dispersion. The tigorasan
solid dispersion comprises tigorasan and a carrier, the tigorasan is one or more of a tigorasan A
crystal form, a tigorasan B
crystal form and a tigorasan amorphous form; the carrier comprises copovidone and
polyethylene glycol; the
mass ratio of the copovidone to the
polyethylene glycol is 1: (0.5-2). The invention also provides a preparation method of the tigorazan
solid dispersion, a tigorazan-containing tablet core and a preparation method thereof, and a tigorazan tablet and a preparation method thereof. According to the method disclosed by the invention, wet
granulation is adopted, so that the preparation process is simpler, the product quality is easier to control, the production efficiency is improved, large-scale production is facilitated, and the prepared tigoraz tablets are good in content uniformity and good in stability.
