title: [Relation between the prolongation of the anti-inflammatory activity of liposome-encapsulated hydrocortisone and liposome composition in experimental arthritis].
abstract: Experiments on rabbits with arthritis have demonstrated the possibility of a 10-fold decrease in the dose of hydrocortisone acetate incorporated into liposomes, administered intraarticularly as compared with a commercial drug in the form of suspension. The antiinflammatory effect was found to be appreciably prolonged (up to 5-6 days) upon the use of dipalmitoylphosphatidylcholine liposomes with 20 mol% cholesterol. Hydrocortisone had a prolongation effect (about 1-2 days) in the lipid phase of multilamellar liposomes from egg lecithin, dimyristoylphosphatidylcholine and distearoylphosphatidylcholine.
