pyrazolone and Pruritus

The nonsteroidal anti-inflammatory drugs are one of the most commonly prescribed classes of drugs used in medical practice. This review discusses the diverse cutaneous reactions associated with nonsteroidal anti-inflammatory drugs. Adverse cutaneous reactions occur most frequently with benoxaprofen, piroxicam, sulindac, meclofenamate sodium, zomepirac sodium, and phenylbutazone. The most serious adverse cutaneous reactions, Stevens-Johnson syndrome and toxic epidermal necrolysis, appear to be most often associated with sulindac and phenylbutazone. Tolmetin and zomepirac sodium, two structurally similar pyrrole derivatives, have been associated with a disproportionate number of cases of anaphylactoid reactions. Among the currently marketed nonsteroidal anti-inflammatory drugs, piroxicam appears to have the highest rate of phototoxic reactions. This phototoxic eruption is most often vesiculobullous.
