Novel salts and cocrystals of lesinurad, processes for their preparation, pharmaceutical compositions comprising these new salt forms and co-crystals, and use of them for treating or delaying progression or onset of diseases or disorders related to activity of uric acid transport 1 (URAT1) proteins are disclosed. These novel forms were characterized by X-ray powder diffraction, differential scanning calorimetry, and other techniques. They can be readily prepared and are suitable for preparation of solid dosage forms owing to their ease of handling and superior pharmacological properties.
本发明揭示了lesinurad的新型盐和共晶体,以及其制备方法、包含这些新盐形式和共晶体的药物组合物,以及将其用于治疗或延缓与尿酸转运1(URAT1)蛋白活性相关的疾病或障碍的进展或发病的用途。这些新型形式通过X射线粉末衍射、差示扫描量热和其他技术进行了表征。它们可以很容易地制备,并且由于易于处理和优越的药理特性,适用于固体剂型的制备。
