Aspirin is a prototype of non-steroidal anti-inflammatory drugs (NSAIDs), and member of the family of salicylates that have in common salicylic acid as the active agent. Next to the inhibitory effects on peripheral prostaglandin synthesis, central mechanisms of action have also been discussed. The blocking action prevents this response and is believed to work in a similar way to prevent tissue inflammation. It was then suggested that different mechanisms lie behind this dose-dependent behaviour, with the anti-thrombin action requiring much higher amounts of acetylsalicylic acid than the anti-aggregating effect. Children and the elderly are particularly susceptible, as their toxicity thresholds are much lower than adults. Acetylsalicylic acid (ASA; Aspirin) is one of the first agents, which its antiglycation effect was witnessed.

Because aspirin inhibits thromboxane production, thus "thinning the blood," it is frequently prescribed in low doses over long periods for at-risk patients to help prevent heart attacks and strokes. In this reaction, a hydroxyl group is converted to an ester, with acetic acid as a byproduct. This action is believed to occur at the anterior (frontal) hypothalamus, a portion of the brain that regulates such functions as heart rate and body temperature.
