In Vivo Clobetasone butyrate (application on the skin; 0.05%; 7 weeks) induces epidermal thinning in skin, Clobetasone butyrate 7 weeks causes much less epidermal thinning in the pig than flurandrenolone (0.05%) or fluocinolone acetonide (0.025%), both of which causes severe atrophy[1]. Animal Model: Large white domestic pig[1] Dosage: 0.5% application on the skin Administration: 7 weeks Result: Caused moderate to slight atrophy.
