Which medication can be used to treat onychomycosis?

Onychomycosis, a fungal infection of the nails, can be effectively treated with antifungal medications. Both fluconazole and itraconazole are azole antifungals that work by inhibiting the synthesis of ergosterol, a vital component of fungal cell membranes, thus leading to cell death.

Fluconazole is often utilized in the treatment of various fungal infections and, while it may not always be the first choice for onychomycosis, it can still be effective, especially for certain types of fungi. Itraconazole, on the other hand, is specifically indicated for the treatment of onychomycosis and has a demonstrated efficacy in penetrating keratinous tissues, where fungi typically reside.

The choice of using either medication may depend on the specific type of fungus involved and the patient's overall health profile, but both options are valid treatments for onychomycosis. Hence, acknowledging that both fluconazole and itraconazole can be utilized in treating this condition leads to the conclusion that the correct answer encompasses both medications.
