Patent AT-E399565-T1: [Translated] COMPOSITIONS FOR THE RAPID AND NON-IRRITATIVE TRANSDERMAL ADMINISTRATION OF PHARMACEUTICALS AND METHODS OF FORMULATION AND ADMINISTRATION THEREOF

Published by National Center for Biotechnology Information (NCBI) | U.S. Department of Health & Human Services | Metadata Last Checked: September 07, 2025 | Last Modified: 2025-09-06
A transdermal delivery system (TDS)for use in treatment of living bodies may be applied as an open (liquid, gel) or closed (patch) article. The TDS is composed of a particular active agent which dictates an associated selection of certain solvents, solvent modifiers, solute modifiers and skin stabilizers with which the medicament forms a true solution that rapidly crosses the skin barrier. The associated selection of the particular solvents, solvent modifiers, solute modifiers and skin stabilizers is based on a balancing of the molecular properties of all the components against the molecular properties of all the components plus the particular active agent. The TDS may also include a source of cellular energy to induce CAMP or cGMP. The TDS improves delivery of active agents having a molecular weight greater than 340 Daltons and increases dosage above 0.25 mg/day for such active agents.
