  • Patent number: 10577379
    Abstract: The present disclosure relates salts of fenofibric acid with berberine or its analogues, their crystalline forms, their preparation methods, and their uses, wherein the salts comprise fenofibric acid as anion and berberine or its analogues as cation. The disclosed salts of fenofibric acid with berberine or its analogues are free of unnecessary cation or anion, such as choline cation in a fenofibric acid salt with choline and chloride ion in a chloride salt of berberine or its analogs, and thus free of side effects caused by such cation or anion, including instability caused by choline and digesting system irritation caused by high acidity caused by the chloride salt of berberine analogs.
