The patient is experiencing white patchy lesions on the tongue and buccal mucosa while on inhalational steroids. This description is indicative of oral candidiasis, a fungal infection commonly seen in patients using inhaled steroids. The appropriate treatment for oral candidiasis involves antifungal medications.
The options provided are:
Cotrimazole is an antifungal medication that is effective against Candida infections. It is often administered as a topical treatment directly to the affected area in cases of oral candidiasis.
Griseofulvin is used primarily for dermatophytic infections of the skin, not oral candidiasis.
Terbinafine is also used mainly for dermatophyte infections, such as those affecting the nails and skin.
Flucytosine is used in combination with other antifungal agents for systemic fungal infections but is not the first-line treatment for oral candidiasis.
Therefore, the drug that can be used to treat this condition is Cotrimazole.
