Nizoclin 2% Dusting Powder is a topical antifungal medication, containing Ketoconazole as its active ingredient at a concentration of 2% (w/w). This powder is designed for the treatment of dermatophytosis (ringworm) and other fungal skin infections in humans. It functions by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes, thereby disrupting the fungal cells' integrity and growth. The powder formulation allows for targeted application and minimal systemic absorption, reducing potential side effects. Nizoclin should be applied sparingly, as directed by a healthcare professional, to the affected areas for optimal therapeutic effect.
