  • Publication number: 20210113563
    Abstract: The invention relates to 4-(4-Cyano-2-thioaryl)dihydropyrimidinones of the formula (I) known from WO 2009/080199(A1) for use in a method for the treatment and/or recurrence rate reduction of a chronic wound selected from different types of ulcers and a chronic wound associated with Behçet's disease wherein the compound of the formula (I) is administered orally and wherein the treatment and/or reduction of recurrence rate of the chronic wound causes one or more of the effects selected from an increased wound closure rate, a reduced wound size, a shorter time to wound closure, an increase of the reepithelialisation of the chronic wound, an increase of the deposition of extracellular matrix such as collagen in the chronic wound, and a reduction of pain related to the chronic wound. The invention further relates to compounds of the formula (I) for use in a method for the treatment of neutrophilic dermatoses or for use in a method for the treatment of autoimmune blistering dermatoses.
