Note: Coal tar is a mixture resulting from the dry distillation of coal, which contains a large number of individual components. Coal tar solution and coal tar spirit are alcoholic extracts of coal tar containing powdered soap bark or polysorbate 80 as surfactant. All three substances are monographed in the DAC.

Coal tar as well as the solution and the spirit have antipruritic and antiphlogistic, antimicrobial, antifungal and photosensitizing properties. They are contained in numerous dermatics and some NRF prescriptions for the treatment of chronic eczema and psoriasis vulgaris. None of the three active ingredients is currently available as a prescription substance, which means that the preparations cannot be made. A suitable alternative must be sought together with the doctor on the basis of the claimed indication.
