5. Pharmacological properties
5.1 Pharmacodynamic properties

Pharmacotherapeutic group: Antipsoriatics for topical use, Tars. ATC code: D05AA.

The preparation has been designed as an aid in the treatment of dry, scaly scalp conditions by incorporating into a shampoo formulation three well known ingredients which have been established as safe and effective for use in this indication. They are as follows:

1.0% distilled coal tar

0.5% salicylic acid


mild keratolytic

1.0% coconut oil


emollient, softening agent and lubricant

The preparation may also be used conveniently to remove any previous topical application.

The active ingredients of the formulation are readily available for intimate contact with the skin, as the shampoo is massaged into the scalp and left on for a few minutes before washing out. This is then repeated in order to produce a rich lather.
