Screening of Dermatology Drugs for Aberrant Use-Patterns: An Application of Epidemiologic Estimates and Measures of Inequality in Drug Use

This study analyzed dermatology drug use patterns in Denmark using data from over 1 million users and more than 2 million prescriptions in 2019. It found significant inequality in drug consumption, with some drugs being used disproportionately. Notable issues include potentially inappropriate use of topical antibiotics like fusidic acid and mupirocin, raising concerns about resistance, and extensive use of potent corticosteroids, which could lead to adverse effects. The study also noted the short duration of minoxidil use, suggesting limited clinical effectiveness. These findings underscore the need for surveillance to identify and address inappropriate prescribing and usage patterns in dermatological treatments.
