Clobetasol Propionate

Clobetasol Propionate is a superpotent topical corticosteroid used for severe, resistant inflammatory dermatoses such as plaque psoriasis and lichen planus, requiring strict duration-of-use limits due to HPA-axis suppression risk. Simson Pharma's Clobetasol Propionate reference standard and impurities support the demanding stability-indicating testing required of this high-potency topical steroid.
