4 Drug and Medication Information
4.1 Drug Indication

Used in the treatment of dandruff and mild to moderately severe seborrheic dermatitis of the scalp.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Chloroxine has an antibacterial action, inhibiting the growth of gram-positive as well as some gram-negative organisms. Also, chloroxine has shown some antifungal activity against certain dermatophytes and yeasts.


5.2 MeSH Pharmacological Classification

Antifungal Agents

Substances that destroy fungi by suppressing their ability to grow or reproduce. They differ from FUNGICIDES, INDUSTRIAL because they defend against fungi present in human or animal tissues. (See all compounds classified as Antifungal Agents.)


Anti-Bacterial Agents

Substances that inhibit the growth or reproduction of BACTERIA. (See all compounds classified as Anti-Bacterial Agents.)


5.3 Mechanism of Action

Although the mechanism of action is not understood, chloroxine may slow down mitotic activity in the epidermis, thereby reducing excessive scaling associated with dandruff or seborrheic dermatitis of the scalp. Chloroxine induces SOS-DNA repair in E. coli, so chloroxine may be genotoxic to bacteria.
