Effect of topically applied flurbiprofen on ultraviolet-induced erythema.

The effect of flurbiprofen, a nonsteroidal antiinflammatory agent, on ultraviolet B-induced erythema was studied in normal volunteers. The effect of various concentrations as well as the effect of multiple applications were evaluated at 4, 8, and 24 hours after irradiation with three MEDs of ultraviolet B. Repeated applications of flurbiprofen during the four- and eight-hour periods following ultraviolet B exposure did not increase the blanching response obtained following a single treatment. A concentration dependent effect of flurbiprofen on blanching was observed with suppression of erythema increasing with increasing concentration of flurbiprofen up to 3%. Further increase in concentration up to 5% offered no added advantage. Significant differences in blanching were also observed at different postirradiation time periods. No cutaneous or systemic complications were reported during the entire study.
