Transition of Topical Therapy Formulation in Psoriasis: Insights from a Canadian Practice Reflective

Patient preferences for psoriasis treatment may affect treatment adherence and disease control; changing topical formulation may improve adherence and patient acceptance of treatment. This study explored dermatologists' reasons for transitioning psoriasis patients from an ointment or gel (Dovobet®) formulation to an aerosol foam (Enstilar®) formulation of calcipotriol and betamethasone dipropionate (Cal/BD), and to assess the success of this transition. Medical records of 81 Canadian patients from 9 dermatologists were retrospectively reviewed for symptoms affecting quality of life, reasons for transitioning treatment, and whether transition was successful. Reasons for transition included efficacy, quality of life, and patient adherence. At follow-up, median psoriasis severity and body surface area affected had decreased from baseline, and patients experienced improved quality of life. Itch and itch-related sleep loss, which were identified as burdensome in 63% of patients at baseline, had resolved in 33% and improved in 54% of patients at follow-up. Dermatologists deemed the transition successful in 85% of patients, with the most common reasons being patient-reported success, clearance of signs/symptoms, and continued prescription refills. Transition from Cal/BD ointment or gel to aerosol foam was generally deemed successful by patients and dermatologists, and was associated with improved quality of life and improved itch control.
