Abstrakt: A preparation of cyclosporine A (CsA) in small liposomes (300 nm) was tested in a rat model of heterotopic cardiac allograft. At a daily dose of 1,5 mg/kg during 14 days, the graft survival rate was 30.4 +/- 2.8 days with a liposome-CsA solution versus 16 +/- 2.3 days with a Cremophore-CsA solution (p less than 0.01). Animals treated with the liposome-CsA preparation exhibited less weight loss than animals treated with cremophore-CsA solution (p less than 0.01). It is likely that the up-take of CsA by macrophages, when incapsulated into liposomes is dramatically enhanced; these cells have been pointed out at targets for IL2 inhibition by CsA.
