The present invention is directed to novel water-soluble pharmaceutically acceptable, crystalline addition salts of (i) an amine containing one or more hydroxyl and/or carboxylic groups with (ii) amino nicotinic acid derivatives of formula (I)
wherein Ra, Rb, Rc and Rd independently represent groups selected from hydrogen atoms, halogen atoms, C1-4 alkyl groups which may be optionally substituted by 1, 2 or 3 substituents selected from halogen atoms and hydroxy groups, and C1-4 alkoxy groups which may be optionally substituted by 1, 2 or 3 substituents selected from halogen atoms and hydroxy groups, and pharmaceutically acceptable solvates thereof.
该发明涉及一种新型水溶性药用可接受的结晶加合盐,该盐包括(i)含有一个或多个羟基和/或羧基的胺与(ii)式(I)的氨基烟酸衍生物之间的结合,其中Ra、Rb、Rc和Rd独立地表示从氢原子、卤原子、可能被1、2或3个卤原子和羟基选择的C1-4烷基组成的基团,以及可能被1、2或3个卤原子和羟基选择的C1-4烷氧基组成的基团,以及其药用可接受的溶剂化合物。
