NCIt definition : A lotion preparation of the olamine salt of ciclopirox, a synthetic hydroxypyridone
derivative with broad-spectrum antifungal and anti-inflammatory activities. Although
its mechanism of action is not well understood, ciclopirox may chelate trivalent cations,
such as Fe3 and Al3 , thereby inhibiting the availability of essential metal co-factors
for enzymes, which may result in a loss of enzyme activities that are essential for
cellular metabolism, organization of cell wall structure, and other crucial cell functions
in a wide variety of fungal species. This agent may also disrupt DNA repair, cell
division signals and mitotic spindles as well as some elements of intracellular transport
in susceptible fungi. Ciclopirox exhibits anti-inflammatory activity by inhibiting
5-lipoxygenase and cyclooxygenase (COX).;
