However, its blood compatibility needs to be further improved. For this we have developed acetylsalicylic acid (ASA, aspirin) loaded PVA membranes. It seems that the slow release of aspirin from the membrane provides a surface concentration of aspirin sufficient for partially inhibiting platelet adhesion. PVA membrane with 531 mu g cm(-2) of ASA loaded, may be selected for hemodialysis applications. This may help to reduce the amount of heparin infused during hemodialysis, thereby reducing the side-effects associated with the systemic administration of heparin.Drug Delivery
