Effects of benoxaprofen on human neutrophil function.
In vitro assays of human neutrophil phagocytosis, adherence, enzyme release, and response to chemotactic factors were utilized to determine the effects of benoxaprofen on these cells. At concentrations of 30 and 300 micrograms/ml benoxaprofen partially inhibited phagocytosis without affecting adherence. High concentrations (300 micrograms/ml) of benoxaprofen, but not aspirin or gold, enhanced the release of the granular enzymes beta-glucuronidase and lysozyme, but not the release of the cytoplasmic enzyme lactic dehydrogenase from both resting and phagocytosing neutrophils. High concentrations (300 micrograms/ml) of benoxaprofen also inhibited the response of neutrophils to chemotactic factors as determined by both the leading front and leukotactic index methods. These unique in vitro effects of this antiinflammatory agent are compatible with recent clinical reports concerning its efficacy and toxicity.[1]References
