Grifulvin V

Grifulvin V is an oral antifungal medication containing microsize griseofulvin. It works by inhibiting fungal cell mitosis (cell division) by disrupting mitotic spindle structures. It binds specifically to keratin in keratin precursor cells, making the newly formed skin, hair, and nails resistant to fungal invasion.

Dosage by Body Weight

Adult dosage is typically 500 mg to 1,000 mg daily in single or divided doses, depending on the severity and site of infection. Pediatric dosage is generally calculated by body weight (approximately 10 mg/kg daily). Grifulvin V must be taken with a fatty meal (such as whole milk or ice cream) to ensure proper absorption.
