Background: Liposomes have been shown to be an effective targeted drug delivery system used to decrease side effects of glucocorticosteroids in the treatment of rheumatoid arthritis.
Materials and Results: Experimental arthritis was induced in rabbits by a single intra-articular administration into the knee joint of poly-D-lysine (molecular weight, 175 kDa) and hyaluronic acid (7.5 mg per administration). To determine temperature readings over the joint a standard radiator was used with a temperature of 32 0C. Large oligolamellar liposomes from different phospholipidsand and cholesterol containing hydrocortisone acetate in lipid phase and prednisolone hemisuccinate in water phase were used.
Conclusion: Intra-articular administration of the water-soluble prednisolone hemisuccinate (0.125 mg) and the lipid-soluble hydrocortisone acetate (0.125 mg) into the knee joint in the aqueous and lipid phases of large oligolamellar TSL (DPPC + 20 mole % cholesterol) prolongs the anti-inflammatory effect produced by glucocorticoids by 7–8 days compared to 1 day for free glucocorticosteroids at a total dose of 2.5 mg and 2 days for phosphatidylcholine-cholesterol liposomes at a total dose of 0.25 mg in rabbits with aseptic arthritis.
