LIPOSOMAL SYSTEMS COMPRISING SPHINGOMYELIN

摘要

The present disclosure provides a liposomal system comprising an aqueous medium having dispersed therein liposomes encapsulating in their intraliposomal aqueous compartment at least one active agent, the aqueous medium being in iso-osmotic equilibrium with said intraliposomal aqueous compartment, the liposomes having a membrane comprising a liposome forming lipids, at least one of which being sphingomyelin (SPM), the liposomal system having increased stability as compared to the same liposomes free of SPM, and in one embodiment being stable during long-term storage, said stability being characterized in that no more than 30% of the at least one active agent is present in the aqueous medium after said storage. Further provided by the present disclosure are a method for storage of liposomes making use of the liposomal system; use of the liposomal system for the treatment of a medical condition or for the diagnostic of a medical condition; a pharmaceutical or diagnostic composition comprising the liposomal system, and a method of treating or diagnosing of a medical condition comprising administering to a subject an amount of the liposomal system.
