5. PHARMACOLOGICAL PROPERTIES

Go to top of the page

5.1 Pharmacodynamic properties

The surface active cationic germicide, benzalkonium chloride, is adsorbed on to dry skin scales, which are a feature of pityriasis capitis and other seborrhoeic scalp conditions. The scales are thereby loosened and attain a net positive charge. In the presence of the anionic foaming agent, sodium lauryl ether sulphate, the dandruff scales are then levitated into the negatively charged surface of the foam, and are thus washed from the hair.

The benzalkonium chloride also acts as a mild antiseptic which improves clinical performance where the condition is exacerbated by the presence of microbes. The major site of action against micro-organisms appears to be the cell membrane, where permeability is altered.

5.2 Pharmacokinetic properties

The effect of Dermax Therapeutic Shampoo is entirely superficial since it acts on the outer surface of the stratum corneum, treating the external manifestations of the recommended clinical indications. For this reason, no pharmacokinetic studies have been undertaken.
