Abstract
Abstract A process for the treatment of psoriasis comprising administering to humans or domesticated animals topically and/or systemically a composition comprising a pharmaceutical carrier and eicosa-5,8,11,14-tetraynoic acid, its congeners, and the lower alkyl esters thereof; in one preferred form of the invention the composition comprises a pharmaceutical carrier and 5,8,11 eicosatriynoic acid; in another preferred form of the invention the composition comprises a pharmaceutical carrier and at least one active compound selected from the groups eicosa-5,8,11,14-tetraynoic acid, its congeners and the lower alkyl esters thereof and at least one compound selected from the group consisting of PGE1, PGE2, PGE3 and the alkyl esters thereof containing from 1 to 8 carbon atoms inclusive, and 13,14-dihydro PGE1 and the alkyl esters thereof containing from 1 to 8 carbon atoms inclusive.
