prostacyclin

 [pros″tah-si´klin]
a prostaglandin, PGI2, synthesized by endothelial cells lining the walls of arteries and veins; it is a potent vasodilator and a potent inhibitor of platelet aggregation. When used pharmaceutically it is called epoprostenol.

pros·ta·cy·clin

(pros'tă-sī'klin),
A potent natural inhibitor of platelet aggregation and a powerful vasodilator.

prostacyclin

/pros·ta·cy·clin/ (pros″tah-si´klin) a prostaglandin, PGI2, synthesized by endothelial cells lining the cardiovascular system; it is a potent vasodilator and inhibitor of platelet aggregation. It is used pharmaceutically as epoprostenol.

prostacyclin

(prŏs′tə-sī′klĭn)
n.
A prostaglandin produced in the walls of blood vessels that acts as a vasodilator and inhibits platelet aggregation.

prostacyclin (PGI2)

[pros′təsī′klin]
a prostaglandin. It is a biologically active product of arachidonic acid metabolism in human vascular walls and a potent inhibitor of platelet aggregation. It inhibits the vasoconstrictor effect of angiotensin and stimulates renin release and has been used to treat pulmonary hypertension.

pros·ta·cy·clin

(pros'tă-sī'klin)
A potent natural inhibitor of platelet aggregation and a powerful vasodilator.

prostacyclin

A short-acting hormone produced by the lining of blood vessels (ENDOTHELIUM) and by the lungs, that limits the aggregation of PLATELETS and is probably of major importance in preventing THROMBOSIS. Prostacyclin has a half-life of only 2–3 minutes.

prostacyclin

powerful vasoconstrictor, released by vascular endothelium

pros·ta·cy·clin

(pros'tă-sī'klin)
A potent natural inhibitor of platelet aggregation and a powerful vasodilator.

prostacyclin

a metabolite of arachidonic acid formed by prostaglandin endoperoxides in the walls of arteries and veins; it is a potent vasodilator and an inhibitor of platelet aggregation. The exogenous form is called epoprostenol.
