A dissolving oral patch with a form a glycyrrhetinic acid that is soluble in water at human mouth temperatures. For higher levels of absorption into local tissues and therefore greater effectiveness for the level of drug used (to minimize risks of side effects) it is preferable to use a water soluble salt of glycyrrhetinic licorice extract (Soluble Glycyrrhetinic Extract, "SGE"). SGE comprises a group of chemical salts of glycyrrhetinic acid that are soluble in water at human mouth temperatures, including potassium salt of glycyrrhetinic acid and other alkali metal salts of glycyrrhetinic acid.
