"Prostacyclin" Natural Recordings by Native Speakers
Prostacyclin is a type of medication that belongs to a class of compounds called prostaglandins, which are synthetic analogues of the naturally occurring substances that the body itself produces. It is a prostaglandin I2 or prostaglandin E1 derivative with a 9, 11-paradibasic carbon skeleton (prostanoid).
Prostacyclin has two main functions: it prevents platelet aggregation (blood clot formation) by inhibiting thromboxane A2 synthesis, which promotes platelet adhesion, and it has a vasodilatory effect, causing blood vessels to relax and widen, which increases blood flow.
Prostacyclin is used in medicine for its antithrombotic effects, particularly in the prevention of complications following heart surgery, such as myocardial infarction, and in patients with a high risk of atherosclerosis (a condition characterized by hardening and narrowing of arteries).
