Ciclopirox olamine
Also Known As: Ciclopirox olamine, Loprox, Batrafen, Mycoster, Penlac, Stieprox, Ciclopirox
Ciclopirox olamine (also called Batrafen, Loprox, Mycoster, Penlac and Stieprox) is a synthetic antifungal agent for topical dermatologic treatment of superficial mycoses. It is most useful against Tinea versicolor.
In contrast to the azoles and other antimycotic drugs, the mechanism of action of ciclopirox is only poorly understood.[2] However, loss of function of certain catalase and peroxidase enzymes has been implicated as 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. [3]
It acts by inhibiting the membrane transfer system by interrupting the Na+ K+ ATPase.[4] 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.[5]
In addition to other formulations, ciclopirox is used in lacquers for topical treatment of onychomycosis (fungal infections of the nails). A meta-analysis of the six trials of nail infections available in 2009 concluded that they provided evidence that topical ciclopiroxolamine had poor cure rates and that amorolfine might be substantially more effective, but more research was required.
