Recurrent aphthous stomatitis (RAS) warrants structured drug therapy when ulcers occur multiple times each month or when severe oral pain makes eating difficult. This presentation calls for a targeted, first-line approach aimed at controlling symptoms and reducing recurrence.
Drug therapy is indicated for patients experiencing multiple episodes of RAS each month and/or severe oral pain with difficulty eating. The clinical goals are to decrease symptoms, reduce ulcer number and size, and extend disease-free periods.
Topical agents form the first-line option, with several distinct categories of topical preparations applied directly to the oral mucosa. The approach addresses both pain relief and ulcer resolution.
