ANTIINFLAMMATORY AGENTS are drugs that are used to reduce inflammatory responses in the body. Although inflammation is essentially a normal defensive mechanism (a reaction to tissue injury, infection, inhalation of foreign proteins), the manifestations may be so serious and inappropriate or involve such discomfort, that treatment with antiinflammatory agents is required. Inflammatory conditions can be acute (as in insect stings) or chronic (chronic asthma, dermatitis and other skin conditions, rheumatoid conditions). A wide range of drugs may be used to treat one or other inflammatory condition, and potential toxicity in relation to the medical condition is an important determinant of choice. The NSAID ANALGESIC group has the widest antiinflammatory use, and their inhibitory antiinflammatory property is due to their cyclooxygenase activity (see CYCLOOXYGENASE INHIBITORS). Here the associated relief of pain is largely attributable to some degree of correction of the underlying inflammatory condition. Some of this group are relatively non-toxic and are available without prescription for use for relatively trivial complaints, e.g. aspirin and ibuprofen.
