The Evolution of Topical Formulations in Psoriasis.

Most people with mild-to-moderate psoriasis manage their disease with topical therapies. However, adherence to topical treatment remains a challenge, as the daily application creates a significant treatment burden. New topical therapeutic options need to offer higher efficacy and better patient acceptability, including easier application, to reduce treatment burden and enhance patient adherence. Topical foam vehicles are innovative alternatives to creams and ointments, addressing many patient challenges with traditional vehicles. Well-designed foam vehicles are easily spread over large areas of the skin, while importantly not leaving a greasy or oily film on the skin after application. Calcipotriol/betamethasone diproprionate aerosol foam is a new psoriasis treatment option that is rapidly effective, offers greater efficacy versus ointment and gel formulations, and has been shown to increase patient treatment satisfaction. Hence, by addressing the several crucial unmet clinical needs in patients with mild-to-moderate psoriasis, this optimized foam formulation is poised to improve treatment follow-through.
