Abstract
New cytidine-diphosphocholine (CDP-choline) salts with long-alkyl chain sulphonic acids suitable for injectable pharmaceutical formulations, but more specifically for oral formulations. Said salts are prepared by a process comprising preparing an aqueous solution of basic CDP-choline, preparing an aqueous sulphonic acid solution, reacting these two solutions together to obtain the required salt, and recovering this salt with a high degree of purity.
