Panthenol

Panthenol is an alcohol derivative of pantothenic acid, a component of the B complex vitamins and an essential component of a normally functioning epithelium. Panthenol exists as a racemic mixture containing both the dextrorotatory form (dexpanthenol) and the levorotatory form (levopanthenol). While pantothenic acid is optically active, only the dextrorotatory form ([DB09357]) is biologically active. Dexpanthenol, the active form of panthenol, is enzymatically cleaved to form pantothenic acid (Vitamin B5), which is an essential component of Coenzyme A that acts as a cofactor in many enzymatic reactions that are important for protein metabolism in the epithelium. Due to its good penetration and high local concentrations, dexpanthanol is used in many topical products, such as ointments and lotions for treatment of dermatological conditions to relieve itching or promote healing. Dermatological effects of the topical use of dexpanthenol include increased fibroblast proliferation and acce
