Dược Động Học :
▧ Absorption :
Rapidly absorbed after oral administration. Mean absorption of ciclopirox after application to nails of all twenty digits and adjacent 5 millimeters of skin once daily for 6 months in patients with dermatophytic onychomycoses was less than 5% of the applied dose. Ciclopirox olamine also penetrates into hair and through the epidermis and hair follicles into sebaceous glands and dermis.
▧ Protein binding :
Protein binding is 94-97% following topical administration.
▧ Metabolism :
Glucuronidation is the main metabolic pathway of ciclopirox.
▧ Route of Elimination :
Most of the compound is excreted either unchanged or as glucuronide. After oral administration of 10 mg of radiolabeled drug (14C-ciclopirox) to healthy volunteers, approximately 96% of the radioactivity was excreted renally within 12 hours of administration. Ninety-four percent of the renally excreted radioactivity was in the form of glucuronides.
▧ Half Life :
1.7 hours for 1% topical solution.
