title: Therapy with and mechanisms of nonsteroidal anti-inflammatory drugs.
abstract: Nonsteroidal anti-inflammatory drugs have anti-inflammatory, analgesic, and antipyretic properties. Although most nonsteroidal anti-inflammatory drugs inhibit prostaglandin synthesis, these agents also have important pharmacologic actions unrelated to their effects on prostaglandins. Among these properties is the ability to inhibit the release of mediators of inflammation from neutrophils and macrophages. These effects are due to the ability of nonsteroidal anti-inflammatory drugs to intercalate into the lipid bilayer of the plasma membrane and thereby disrupt protein-protein and protein-lipid interactions critical for cell responses (eg, calcium translocations, membrane phospholipid turnover). Our data, for example, indicate that nonsteroidal anti-inflammatory drugs exert direct inhibitory actions at the regulatory GTP protein (G protein) within the plasma membrane. This exhibit examines the evidence for diverse mechanisms of action of nonsteroidal anti-inflammatory drugs including effects directed at the G protein as well as new evidence that nonsteroidal anti-inflammatory drugs regulate the expression of the cyclooxygenase enzyme at the level of gene transcription.
