Ciclopirox olamine (also called Batrafen Loprox, Penlac and Stieprox) is a synthetic antifungal agent for topical dermatologic use. Antifungal nail chelation with critical trivalent cations resulting in downstream effects.
It is most useful against Tinea versicolour.[1]
Mechanism
Loss of function of certain catalase and peroxidase enzymes has been implicated the mechanism of action as well as various other components of cellular metabolism. In a study conducted to further elucidate ciclopirox's mechanism, several Saccharomyces cerevisiae mutants were screened and tested. Results from interpretation of the effects of both the drug treatment and mutation suggested that ciclopirox may exert its effect by disrupting DNA repair, cell division signals and structures (mitotic spindles) as well as some elements of intracellular transport [2]
It acts by inhibiting the membrane transfer system by interrupting the Na+ K+ ATPase.[3]. It is currently being investigated as an alternative treatment to ketoconazole for seborrhoeic dermatitis as it suppresses growth of the yeast Malassezia furfur. Initial results show similar efficacy to ketoconazole with a relative increase in subjective symptom relief due to its inherent anti-inflammatory properties.[4]
