The present invention provides a pharmaceutical composition for the lubrication of joints, the pharmaceutical composition comprising a non-ionic tonicity agent comprising a polyol, and liposomes comprising at least one membrane comprising at least one phospholipid (PL) selected from a glycerophospholipid (GPL), said GPL having two C-Chydrocarbon chains, being the same or different, and sphingomyelin (SM) having a C-Chydrocarbon chain, the pharmaceutical composition being essentially free of an additional pharmaceutically active agent, wherein the at least one membrane has a phase transition temperature in the range of about 20° C. to about 39° C. and the joint has a joint temperature which is above the phase transition temperature.

Liposomal formulation for joint lubrication

The present invention provides a pharmaceutical composition for the lubrication of joints, the pharmaceutical composition comprising a non-ionic tonicity agent comprising a polyol, and liposomes comprising at least one membrane comprising at least one phospholipid (PL) selected from a glycerophospholipid (GPL), said GPL having two C12-C18 hydrocarbon chains, being the same or different, and sphingomyelin (SM) having a C12-C18 hydrocarbon chain, the pharmaceutical composition being essentially free of an additional pharmaceutically active agent, wherein the at least one membrane has a phase transition temperature in the range of about 20&#xb0; C. to about 39&#xb0; C. and the joint has a joint temperature which is above the phase transition temperature.

Provided are modified lipid compounds and their use in the formation of lipid assemblies. Also provided are lipid assemblies including (a) an amphoteric lipid including in covalent association with (i) one or more acyl chains; (ii) one or more weak base moiety; (iii) one or more weak acid moiety; the lipid assembly also including (b) one or more additional lipids, at least one of which being a zwitterionic lipid. In some embodiments, the amphoteric lipid is a compound including (a) a tri-functional moiety; (b) two non-phosphate lipid chains associated with two of the functional moieties of said tri-functional moiety; (c) optionally a spacer moiety associated with the third of the functional moieties of said tri-functional moiety; and (d) a polyalkylamine optionally including a short peptide with one to several carboxylic acid residues. Further provided are the uses of the lipid assembly, inter alia, for transfection or cancer treatment.
