New crystalline forms of 5-Chloro-3-(4-methanesulfonylphenyl)-6'-methyl-[2,3']bipyridinyl in the form of stable salts and cocrystals with pharmaceutically acceptable inorganic and/or organic acids. Organic acid is selected from succinic, adipic, fumaric, benzoic, salicylic, 1-hydroxy-2-naphthoic, 3-hydroxy-2-naphthoic acid and saccharin and inorganic acid is selected from hydrochloric, hydrobromic, nitric and sulfuric acid. By the appropriate use of the salts and cocrystals described herein it is possible to modulate and ensure the consistency of the physicochemical properties of the active pharmaceutical ingredient and enable its administration in different dosage forms including for oral delivery.
新的结晶形式为稳定盐和与药用可接受的无机和/或有机酸形成的共晶体的5-氯-3-(4-甲磺基苯基)-6'-甲基-[2,3']联吡啶。有机酸选自琥珀酸、己二酸、富马酸、苯甲酸、水杨酸、1-羟基-2-萘酸、3-羟基-2-萘酸和糖精,无机酸选自盐酸、溴酸、硝酸和硫酸。通过适当使用本文所描述的盐和共晶体,可以调节和确保活性药物成分的物理化学性质的一致性,并使其能够以不同剂型包括口服给药形式进行给药。
