Griseofulvin

Griseofulvin (marketed under the proprietary name Grifulvin V by Orthoneutrogena Labs, according to FDA orange book) is an antifungal drug that is administered orally. It is used both in animals and in humans, to treat fungal infections of the skin (commonly known as ringworm) and nails. It is produced by culture of some strains of the mold Penicillium griseofulvum, from which it was isolated in 1939.
