Acetylsalicylic acid CAS#50-78-2
1. Pain Relief and Anti-Inflammatory: Aspirin is a proven NSAID, widely used for its anti-inflammatory and pain-relieving properties.
2. Antithrombotic Effects: It inhibits platelet aggregation, providing antithrombotic effects, making it effective in preventing blood clots.
3. Cardiovascular Benefits: Aspirin lowers the risk of fatal myocardial infarction and stroke, improving heart health.
4. Cancer Prevention: Research shows that aspirin may reduce the likelihood of developing colorectal cancer, enhancing its therapeutic value.
Aspirin, chemically referred to as acetylsalicylic acid, is a nonsteroidal anti-inflammatory drug (NSAID) initially employed for its anti-inflammatory and pain-relieving properties. Subsequently, researchers found that aspirin inhibits platelet clumping, thereby producing antithrombotic effects. As scientific investigations into aspirin have progressed, numerous additional applications have been identified. For instance, aspirin has been shown to lower the fatality rate associated with myocardial infarction and stroke, as well as decrease the likelihood of developing colorectal cancer.
