Abstract
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.
