Roflumilast may effectively reduce symptoms and flare-ups in recurrent aphthous stomatitis, suggests study
Roflumilast may effectively reduce symptoms and flare-ups in recurrent aphthous stomatitis, suggests study published in the International Journal of Dermatology.
Severe recurrent aphthous stomatitis (RAS) represents a therapeutic challenge because of its impact on the patient's quality of life. Additionally, no approved systemic therapies are available. Roflumilast, a phosphodiesterase-4 inhibitor, has shown promise in other inflammatory dermatological conditions. This study aimed to assess the characteristics, effectiveness, and safety of roflumilast in treating RAS in routine clinical practice.
This is a single cohort ambispective observational study conducted in five Spanish centers. Twenty-two patients with RAS treated with roflumilast participated. Data collection included demographic, clinical, and outcome variables. Statistical analysis compared the outcomes of 12 weeks of roflumilast treatment with a similar prior period without treatment. Results: During treatment with roflumilast, a significant reduction in flare-ups (88%) and oral ulcers (94%) was observed compared to the untreated period. A reduction in pain (66%) and ulcer duration (63%) was observed. Adverse effects (AEs) occurred in 13 patients, predominantly headache and gastrointestinal disturbances. Most of these were self-limiting or manageable with dose adjustment. Treatment was withdrawn in three cases, mainly because of AEs.
