Neutral stabilization complex for CI-979 HCl, a cognition activator

摘要

A solid composition for stabilizing the dosage of cognition activator CI-979 HCl by formation of a complex with cyclic polydextrose. In particular, compositions with HP beta CD have been found to stabilize CI-979 HCl even in the presence of other excipients such as sodium carbonate. Pharmaceutical formulations for the treatment of cognitive disorders in humans are based on the stabilizing composition of CI-979 HCl and cyclic polydextrose, including appropriate amounts of other excipients or components as known in the formulation art.
