Calcipotriol/Betamethasone Dipropionate Aerosol Foam for Plaque Psoriasis: A Prospective, Observational, Non-Interventional, Single-Center Study of Patient Adherence and Satisfaction in Daily Use

Background: Psoriasis is a chronic inflammatory disease that has a negative impact on patients' quality of life. Patients with mild–moderate psoriasis can be treated with topical medications, such as the combination drug calcipotriol/betamethasone dipropionate (Cal/BD). Objectives: This study investigated the adherence of psoriasis patients to therapy with Cal/BD aerosol foam, as well as their satisfaction with the treatment’s efficacy, safety, and effect on their quality of life. Methods: Patients with mild–moderate plaque psoriasis were eligible to participate in this open-label, non-placebo controlled, prospective single-center study. Adherence to treatment was assessed using the Morisky-Green scale 4 and 12 weeks after the start of treatment. Satisfaction with the treatment was assessed using the abbreviated Treatment Satisfaction Questionnaire for Medication (TSQM-9). The severity of psoriasis was assessed on the mIGA and PGA scales, and the impact on quality of life was assessed using the PDI and DLQI scales. Results: A total of 65 patients entered the study. Adherence to treatment was good, with 73.8% of patients showing high adherence at 12 weeks. Satisfaction was also good, with 46 patients (70.8%) being completely satisfied. Conclusions: Over a 4-week period, patients treated with Cal/BD aerosol foam had significant improvement in disease severity that was directly related to treatment adherence.
