4 Drug and Medication Information
4.1 Drug Indication

Indicated for the treatment of fungal infections as a salt form. No therapeutic indications on its own.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Zinc undecylendate acts as a fungistatic agent but fungicidal activity may be observed with chronic exposure in high concentrations. It is effective against _Candida albicans_. It is proposed that undecylenic acid exerts antimicrobial actions via interacting with nonspecific components in the cell membrane.


5.2 ATC Code

D - Dermatologicals

D01 - Antifungals for dermatological use

D01A - Antifungals for topical use

D01AE - Other antifungals for topical use

D01AE04 - Undecylenic acid


5.3 Absorption, Distribution and Excretion

Absorption

Undecylenic acid may be absorbed through the skin [MSDS].

5.6 Mechanism of Action

Undecylenic acid demonstrated effectiveness against _Candida albicans_, which is an opportunistic pathogenic yeast with two cellular morphologies: the round yeast form and the filamentous form with elongated hyphae. Hyphae formation is associated with active infections and virulence. A study proposed that undecylenic acid inhibits biofilm formation of _Candida albicans_ with optimal concentration above 3 mM and disrupts hyphal growth, which is the morphological transition from yeast to filamentous phase, at concentration above 4 mM. Under the drug treatment, hyphal formation related genes, like HWP1, were significantly reduced in transcriptional level leading to poor biofilm formation. Both biofilm and hyphae formation are critical virulence factors for the initiation of skin infection and late development of disseminated infection. Undecylenic acid may also inhibit enzyme involved in lipid metabolism and abolish germ tube formation by carrying protons across the plasma membrane, thus altering cytoplasmic pH.
