AAPD-QE Practice Exam

Triamcinolone acetonide is the topical corticosteroid that has gained FDA approval specifically for the treatment of aphthous ulcers. This medication functions by reducing inflammation and controlling immune responses, which can help alleviate the pain and discomfort associated with these painful mouth sores.

The approval of triamcinolone acetonide for this particular condition is based on its efficacy demonstrated in clinical studies, where it has been shown to promote healing and provide symptomatic relief. This specific approval makes it a go-to option for practitioners when managing patients suffering from aphthous ulcers.

In contrast, other corticosteroids listed, such as hydrocortisone, fluticasone, and clobetasol, are used for various inflammatory conditions but are not specifically indicated by the FDA for the treatment of aphthous ulcers. While they may possess anti-inflammatory properties, their lack of specific approval for this condition means they are not the recommended first-line treatment for aphthous ulcers.
