Pharmacodynamics
Griseofulvin is an antibiotic produced by the mold Penicillinum nigricans, a fungistatic agent that is active against various dermatomycetes (trichophytos, microsporums, epidermophytos). The drug inhibits the division of fungal cells in metaphase, disrupting the structure of the mitotic spindle. griseofulvin accumulates to varying degrees in the cells of the skin, hair, nails, providing resistance to fungal infection. With the death of the affected keratin, it is replaced with healthy ones.

It is metabolized in the liver with the formation of the main metabolites: 6-methylgriseofulvin and a glucuronide derivative. The half-life is 24 hours. It is excreted by the kidneys. Less than 1% is excreted unchanged in urine, 36% in feces.
