Official answer

Tolsura and Sporanox are both capsules containing the azole antifungal itraconazole, however they are different strengths, they are formulated differently, and cannot be interchanged or substituted.

Tolsura is NOT indicated for the treatment of onychomycosis of the toenail and fingernail due to dermatophytes (tinea unguium), whereas Sporanox is indicated for onychomycosis.
