4 Drug and Medication Information
4.1 Drug Indication

Cetalkonium is used as a surfactant, germicide, fungicide, mildew preventive agents in silicone-based water repellents, emulsifier, disinfectant, topical anti-infective, and antiseptic antimicrobial for pharmaceuticals. For its chemical properties and its antiseptical characteristics, cetalkonium can be used in a wide variety of products as part of the formulations and it is also determined to be an active antiseptic ingredient in over-the-counter preparations.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Cetalkonium is an antimicrobial agent and it has shown to be effective against both gram-positive, gram-negative bacteria and fungi. From this property, it has been shown to present a better activity against the gram-negative organisms.


5.2 Absorption, Distribution and Excretion

Absorption

Cetalkonium is used mainly topically and it is not absorbed. When administered orally and parenterally, cetalkonium absorption may happen but it is very insignificant.


Route of Elimination

As cetalkonium is not absorbed, this pharmacokinetic property is not relevant. When administered orally, most of the administered dose is excreted unchanged in the feces as it is very poorly absorbed.


Volume of Distribution

As cetalkonium is not absorbed, this pharmacokinetic property is not relevant.


Clearance

As cetalkonium is not absorbed, this pharmacokinetic property is not relevant.


5.3 Metabolism/Metabolites

As cetalkonium is not absorbed, this pharmacokinetic property is not relevant.


5.4 Biological Half-Life

As cetalkonium is not absorbed, this pharmacokinetic property is not relevant.


5.5 Mechanism of Action

The activity of cetalkonium is based on the creation of a positive charge which permits a bio-adhesive property to negative surfaces. This property allows cetalkonium to disrupt the cell membrane, inactivate enzymes and denature proteins. This type of mechanism allows this type of agents to present a broad spectrum.
