The commonly used treatment for tinea corporis, also known as ringworm, is topical antifungals. This condition, which is a fungal infection of the skin, responds effectively to medications designed to target fungal organisms. Topical antifungals, such as clotrimazole, miconazole, or terbinafine, work by directly acting on the fungi causing the infection, leading to its eradication.

These medications are usually preferred due to their localized effects, minimal systemic absorption, and relatively lower risk of side effects compared to oral medications. In cases where topical treatment is insufficient, or if the infection is widespread or more severe, oral antifungals may be considered, but they are not the first line of treatment.

Other options like oral antibiotics and oral antivirals are not suitable for fungal infections. Oral antibiotics target bacterial infections, while oral antivirals are intended for viral infections. Topical corticosteroids may provide symptom relief from inflammation but do not address the underlying fungal infection and can sometimes exacerbate a fungal condition if used alone. Thus, the use of topical antifungals is the standard and most appropriate approach for treating tinea corporis.
