4. Prostaglandins and thromboxanes, thus produced in the body, act as important mediators promoting fever, pain and inflammation, and formation of thrombi.
5. Aspirin, administered in different doses, inhibits the cyclooxygenase enzymes, thus inhibiting the production of prostaglandins and thromboxanes.
6. Inhibition of prostaglandin and thromboxane production by aspirin, thus result in control of fever, pain and inflammation, and inhibit formation of thrombi.
