Which FDA approved topical corticosteroid is used for the treatment of aphthous ulcers?

Triamcinolone acetonide is recognized for its effectiveness in treating aphthous ulcers, also known as canker sores. This corticosteroid works by reducing inflammation and alleviating pain, making it particularly useful in the management of these painful lesions. Given its formulation in the form of an orabase paste, triamcinolone acetonide can provide localized treatment directly to the ulcer, promoting faster healing and offering comfort to the patient.

While hydrocortisone, betamethasone, and clobetasol propionate are all corticosteroids, they are not typically the preferred treatment for aphthous ulcers. Hydrocortisone is generally less potent and may not provide the same level of relief for the inflammation associated with these ulcers. Betamethasone is a stronger corticosteroid, but it is often used for other dermatological conditions rather than directly for aphthous ulcers. Clobetasol propionate is a very potent topical steroid and is more often reserved for severe skin conditions, making it less suitable for the treatment of aphthous ulcers where lesser preparations are typically effective and safer for use in the oral cavity.
