  • Patent number: 11427528
    Abstract: The present invention relates to Form IV of fenofibrate and its preparation methods thereof. Its X-ray powder diffraction pattern expressed as 2? angle has characteristic peaks at 14.15±0.2°, 15.94±0.2°, 16.49±0.2°, 17.45±0.2°, 20.21±0.2°, and 22.87±0.2°. The present invention also provides preparation methods of Form IV. The preparation methods are simple, easy to operate, short, and have good repeatability. The methods are also non-toxic and non-polluting by using water as a medium and using a pharmaceutically accepted excipient, such as polyvinylpyrrolidone or polyvinyl alcohol as an inducer. The results of stability experiments (light exposure, high humidity and grinding) and solubility tests show that Form IV is stable and has a higher solubility than the prior art crystal form.
