It is important to use the correct amount of topical steroid for your eczema, as instructed by your healthcare professional. Topical steroids should be applied with clean hands so that the skin just glistens. It can sometimes be difficult to judge how much steroid to use and there are guidelines on the amount required to cover body areas that are affected by eczema. These are based on the Finger Tip Unit (FTU), and explained in detail in our fact sheet which you can download as a pdf from the related documents to the right of this page.
Clobetasol propionate is a man-made corticosteroid that is used on the skin (topically). It is available as foam, shampoo, cream, gel, lotion, ointment, solution, and spray. It is similar to alclometasone (Aclovate), hydrocortisone valerate (Westcort), halobetasol ( Ultravate ) and several others. Topical clobetasol is used to treat certain scalp and skin conditions such as psoriasis , rashes, and dermatitis . Corticosteroids have potent anti-inflammatory actions and also suppress the immune response. Clobetasol is a very potent topical corticosteroid and should only be used for a short period of time. Long term use of topical clobetasol propionate can cause serious systemic side effects and should be avoided.
In summary, the three bioequivalence approaches that are currently consistently accepted by regulatory authorities are bioequivalence studies with clinical endpoints, in-vivo pharmacodynamic studies (in particular VCA for topical corticosteroid products), and waivers for topical solutions. Also, most require pharmacokinetic studies if there are safety concerns relating to systemic exposure. However, it is refreshing to see that the regulatory authorities are giving credence to alternative science-based methods for demonstration of bioequivalence, rather than insistence on clinical endpoint studies.
