Abstract

The effect of amphiphlic non-steroidal anti-inflammatory drugs (NSAIDs) like Ibuprofen (Ibu) a white insoluble powder pKa = 4,31 on liposomal bilayer as biomembrane model, plays a crucial role in understanding their mechanism at the molecular level. To explain their activity and correlate it with the chemico-physical properties of the drug, the thermal behaviour of the hydrated multilamellar vesicles (liposomes) of dimyristoylphosphatidylcholine (DMPC) in the presence of increasing amounts of both Ibu as well of its Na-salt (Na-Ibu) have been studied at pH = 3.0 and at pH = 7.0 by means of Differential Scanning Calorimetry (DSC) technique.
