Prostacyclin (also called prostaglandin I2 or PGI2) is a prostaglandin member of the eicosanoid family of lipid molecules. It inhibits platelet activation and is also an effective vasodilator. When used as a drug, it is also known as epoprostenol. [1] . The terms are sometimes used interchangeably. [2]

Prostacyclin, a prostanoid metabolized from endogenous arachidonic acid through the cyclooxygenase (COX) pathway, is a potent vasodilator that has been identified as one of the most effective drugs for the treatment of pulmonary arterial hypertension.

2023年8月28日 · Prostaglandin I2 (PGI), or prostacyclin, is one of the prostanoids, a group of local hormones that are best known for their roles in mediating inflammation. However, they also perform many other roles in maintaining homeostasis. PGI2 acts as a vasodilator and a potent inhibitor of platelet aggregation.

Prostacyclin is a powerful cardioprotective hormone released by the endothelium of all blood vessels. Prostacyclin exists in equilibrium with other vasoactive hormones and a disturbance in the balance of these factors leads to cardiovascular disease …

Prostacyclin refers to a member of the endogenous prostanoid family that is produced from arachidonic acid. It is released by pulmonary artery endothelial cells in the pulmonary circulation and binds to a cell-surface G-protein-coupled receptor on target cells.

Prostacyclin (PGI 2) is a member of the prostaglandin family of bioactive lipids. Its best-characterized role is in the cardiovascular system, where it is released by vascular endothelial cells, serving as a potent vasodilator and inhibitor of platelet aggregation.

Prostacyclin therapy is the oldest and most widely used class of medication used in the treatment of PH. Summer 2016. What is prostacyclin therapy? You have now been diagnosed with pulmonary arterial hypertension (PAH) and your PH care team may have recommended starting prostacyclin therapy.

Medications which aim to compensate for missing prostacyclin – known as prostacyclin replacement therapies – play a critical role in blood vessel dilation improving lung function and cardiac performance.

Prostacyclin is the primary prostaglandin product of endothelial cells. Though chemically more stable than TxA 2, prostacyclin non-enzymatically converts to an inactive product, 6-keto-PGF 1α. Prostacyclin enhances microvascular blood flow by potent vasodilation.

1981年8月18日 · Prostacyclin (PGI2) is the product of arachidonic acid metabolism generated by the vessel wall of all mammalian species studied, including man. Prostacyclin is a potent vasodilator and the most potent inhibitor of platelet aggregation so far described.
