5.1    Pharmacodynamic properties

Coal tar has been used dermatologically for hundreds of years and has been shown to be safe and effective in the treatment of scaly skin conditions such as psoriasis. The British Pharmacopoeia contains monographs on coal tar and coal tar solution, and many formulations of coal tar are used in hospitals throughout the country. The coal tar used in Psoriderm bath additive has been specially distilled and is based on a neutral fraction, which has been shown to be effective in the treatment of psoriasis.

The precise mechanism of action of coal tar is not understood, largely as a result of it comprising up to 10000 components. There is evidence that topical application of coal tar improves psoriasis by reducing the excessive rate of mitotic epidermal cell division.

5.2 Pharmacokinetic properties

Dry scales, which are a common feature of psoriasis, generally reduce the effectiveness of topically applied treatments by reducing absorption of the active ingredient. An established means of overcoming this problem is to add a mild softening agent such as lecithin. In the case of Psoriderm bath additive, however, no such softening agent is included because the dosage and administrative regime involves prolonged soaking (5 minutes) in a warm water emulsion which achieves a similar effect.
