PHARMACEUTICAL COMPOSITIONS AND METHOD FOR PREPARING PHOSPHATIDYLSERINE COMPOSITIONS USEFUL IN TREATING CENTRAL NERVOUS SYSTEM DISORDERS WITHOUT EFFECTS ON BLOOD COAGULATION

摘要

Processes are provided herein for the preparation of phospholipid compositions comprised of a mixture of phosphatidylserine and phosphatidylethanolamine in a specified ratio. Such compositions have activity against disorders of the central nervous system but without secondary haematic coagulation effects. Particularly useful synergistic compositions comprise from 60 to 75% by weight of phosphatidylserine and from 40 to 25% by weight of phosphatidylethanolamine.
