Antiplatelet drug

Antiplatelet drug

Antiplatelet drugs (pronunciation: an-tee-plate-let drugs) are a group of medicines that prevent blood cells called platelets from sticking together and forming a blood clot.

Etymology

The term "antiplatelet" is derived from the prefix "anti-" meaning against, and "platelet", referring to the type of blood cell that these drugs act upon.

Mechanism of action

Antiplatelet drugs work by inhibiting the function of platelets. They prevent the formation of blood clots by blocking the enzymes or receptors that platelets need to stick together. This reduces the risk of heart attacks and strokes, which are often caused by blood clots.

Types of Antiplatelet drugs

There are several types of antiplatelet drugs, including:

• Aspirin
• Clopidogrel
• Ticagrelor
• Prasugrel

Each of these drugs works in a slightly different way to prevent platelet aggregation.

Side effects

Like all medications, antiplatelet drugs can have side effects. These may include:

• Bleeding
• Bruising
• Upset stomach
• Rash

If you experience any of these side effects while taking an antiplatelet drug, you should contact your healthcare provider immediately.
