Based on 11 publication(s) in Google Scholar
Ciclopirox olamine (Ciclopirox ethanolamine) is a synthetic and orally active antifungal agent that can be used for superficial mycoses reseaech. Ciclopirox olamine has a very broad spectrum of activity and inhibits dermatophytes, yeasts, molds, and many Gram-positive and Gram-negative species pathogenic. Ciclopirox olamine also has anticancer and anti-inflammatory effect.
