Mechanism of anthralin inflammation. 2. Effect of pretreatment with glucocorticoids, anthralin and removal of stratum corneum.
The inflammatory dose-response to anthralin was measured in human skin 24 h after pretreatment with topical corticosteroids and anthralin, and 48 h after removal of the stratum corneum with adhesive tape. Anthralin inflammation was increased after 1% hydrocortisone application and decreased by 0.1% betamethasone valerate and 0.05% clobetasol propionate; although the difference between these effects was not significant, the difference between the effect of hydrocortisone and clobetasol propionate was. Anthralin inflammation was not significantly affected by pretreatment with anthralin and was reduced, although not significantly by removal of the stratum corneum. The finding that anthralin inflammation is not altered in skin in which aryl hydrocarbon hydroxylase (AHH) activity is increased and that anthralin inflammation may be altered in situations in which AHH activity is unchanged, excludes a direct relationship between anthralin inflammation and AHH activity.
