Aspirin, also known by its chemical name acetylsalicylic acid, is a medication commonly used to relieve pain, reduce inflammation, and lower fevers. It belongs to a class of drugs known as nonsteroidal anti-inflammatory drugs (NSAIDs). Aspirin works by inhibiting the production of certain chemicals in the body that contribute to inflammation, pain, and fever.
In addition to its analgesic (pain relief) and antipyretic (fever-reducing) properties, aspirin is often used in lower doses as an antiplatelet agent to reduce the risk of blood clots, stroke, and heart attack. It achieves this by preventing the aggregation of platelets in the blood.
Aspirin can have side effects, including stomach irritation and an increased risk of gastrointestinal bleeding. It is not recommended for use in children with viral infections due to the risk of Reye's syndrome, a rare but serious condition.
As with any medication, it is important to use aspirin as directed by a healthcare professional, and to be aware of any contraindications or interactions with other medications.
