Figure 1.1. Metabolism of arachidonic acid
Despite the diverse chemical structure of aspirin-like drugs, the antinociceptive effect of NSAIDs is mainly due totheir common property of inhibiting cyclooxygenases involved in the formation of prostanoids. Prostanoids areformed by most cells and act as autocrine and paracrine lipid mediators. They are n
