Prostacyclin, the labile prostanoid product of arachidonic acid metabolism in vascular endothelium, is the most potent known inhibitor of platelet aggregation and is highly effective in relaxing vascular smooth muscle. Its production is probably critically important in the maintenance of an intact vasculature. Although there is some evidence that prostacyclin circulates as a hormone, it is probably most important as a locally active agent in preventing thrombosis and maintaining patent vessels. Several factors can influence prostacyclin production, the most important of which probably act locally at sites of vessel wall injury. The most promising therapeutic approaches toward using prostacyc..View full abstract
