What is the main action of aspirin?

Aspirin, an acetylated salicylate (acetylsalicylic acid), is classified among the nonsteroidal antiinflammatory drugs (NSAIDs). These agents reduce the signs and symptoms of inflammation and exhibit a broad range of pharmacologic activities, including analgesic, antipyretic, and antiplatelet properties.

What is the pharmacodynamic action of aspirin?

Pharmacology/Pharmacokinetics Aspirin is rapidly absorbed in the upper gastrointestinal (GI) tract and results in a measurable inhibition of platelet function within 60 minutes. This antiplatelet effect is associated with prolongation of the bleeding time and inhibition of TXA2-dependent platelet aggregation.

What is the mechanism of action of aspirin as an antiplatelet agent?

Mechanism of action Aspirin works by irreversibly inhibiting the enzyme cyclo-oxygenase (COX-1) which is required to make the precursors of thromboxane within platelets. This reduces thromboxane synthesis. Thromboxane is required to facilitate platelet aggregation and to stimulate further platelet activation.

What are aspirin good for?

Aspirin is a common drug for relieving minor aches, pains, and fevers. People also use it as an anti-inflammatory or a blood thinner. People can buy aspirin over the counter without a prescription. Everyday uses include relieving headache, reducing swelling, and reducing a fever.

How does aspirin work in blood clotting?

Aspirin reduces the stickiness of platelets, and this helps prevent the platelets from sticking to the inside of an artery and forming a thrombus. This reduces the risk of you having a heart attack or stroke. When aspirin is used in this way, it is often referred to as ‘low-dose’ aspirin.

What is antiplatelet action?

Antiplatelets work by making your blood less sticky. This prevents arteries and stents from being plugged by clots.

What is aspirin good for?

Aspirin is used to reduce fever and relieve mild to moderate pain from conditions such as muscle aches, toothaches, common cold, and headaches. It may also be used to reduce pain and swelling in conditions such as arthritis. Aspirin is known as a salicylate and a nonsteroidal anti-inflammatory drug (NSAID).

Is aspirin a blood thinner or anticoagulant?

A: Aspirin is a type of blood thinner called an antiplatelet. Antiplatelets reduce your blood cells’ ability to clump together to form a clot. If you have heart disease, you’re probably familiar with taking a low dose of aspirin to help prevent heart attack.

Is aspirin an antithrombotic?

Thus, aspirin has the potential to be both antithrombotic and thrombogenic. Low doses of aspirin (325 mg or less) inhibit cyclo-oxygenase in platelets and vascular wall cells, but the inhibitory effect on platelet thromboxane A2 synthesis is greater and lasts longer than its effect on vascular wall PGI2 synthesis. 1.
