How Griseofulvin 250 mg works
Griseofulvin 250 mg works by stopping the growth and multiplication of fungi. It interferes with fungal cell division by disrupting structures needed for their growth, so the infection cannot spread. At the same time, it binds to keratin (a protein in skin, hair, and nails) and makes these tissues resistant to fungal infection. As new healthy tissue grows, it gradually replaces the infected part, helping to clear the infection over time.
