A coating for a medical device, the device generally being of the type which is to be used internally in a subject, includes a transglutaminase (TGase) inhibitor. The Tgase inhibitor effectively prevents the activity of any Tgase involved in clot formation or clot stability. Preferably, the transglutaminase inhibitor is a factor XIIIa inhibitor. The coating may be prepared by suitable processes such as esterification. The coating may be immobilized on a suitable medical device in a number of ways and is preferably included in a TGase inhibitor containing polymer. The coating may also include a suitable antimicrobial agent.
