What is a primary effect of using aspirin?

Using aspirin primarily functions as an effective anti-inflammatory medication. It inhibits the enzyme cyclooxygenase (COX), which plays a crucial role in the synthesis of prostaglandins. These compounds are involved in the inflammatory response, and by reducing their production, aspirin can alleviate symptoms associated with inflammation such as pain, swelling, and fever. This property makes aspirin valuable in managing various conditions such as arthritis, muscle injuries, and other inflammatory disorders, thereby allowing individuals to experience relief from discomfort.

While aspirin can have side effects, such as gastrointestinal irritation, the primary therapeutic action is its ability to reduce inflammation. This distinguishes it from other possible effects like enhancing mental alertness or providing hypnotic effects, which are not relevant to its main use in athletic training or medicine.
