What is Aspirin?
Aspirin is a well-known medication belonging to the nonsteroidal anti-inflammatory drug (NSAID) class. It is widely used to relieve pain, reduce fever, and decrease inflammation. In lower doses, It is also used to prevent heart attacks, strokes, and blood clots by reducing platelet aggregation in the blood. This versatile medicine comes in multiple forms, including Aspirin tablets, capsules, and chewable pills, making it suitable for adults with various health needs.
Aspirin Used For
Aspirin is commonly prescribed and used for the following purposes:
-
Relief from mild to moderate pain such as headaches, toothaches, and menstrual cramps
-
Management of arthritis and joint inflammation
-
Reduction of fever and discomfort caused by colds or infections
-
Prevention of heart attacks and ischemic strokes in individuals with cardiovascular risks
-
Maintenance therapy after certain cardiac procedures or surgeries
Chemical Composition
The active ingredient in Aspirin is acetylsalicylic acid, a compound derived from salicylic acid. It works by blocking specific enzymes (COX-1 and COX-2) involved in the production of prostaglandins — chemicals responsible for pain, inflammation, and fever.
Aspirin Mechanism
Aspirin works through irreversible inhibition of cyclooxygenase (COX) enzymes, reducing the synthesis of prostaglandins and thromboxanes. This dual mechanism not only provides pain and fever relief but also prevents platelets from clumping together, lowering the risk of clot formation that could lead to a heart attack or stroke.
How It Helps Manage Pain and Prevent Heart Issues
Aspirin helps reduce inflammation and discomfort by targeting the root cause — prostaglandin production. For cardiac patients, low-dose Aspirin tablets act as an antiplatelet therapy, ensuring smoother blood flow and preventing clot-related complications. This makes it an essential preventive medicine in cardiovascular care.
What Are Other Benefits

-
Reduces the risk of recurrent stroke or heart attack
