Summary for Patent: 9,931,403

Title:	Non-aqueous patch
Abstract:	Non-aqueous patches comprising lidocaine, which is not dissolved and is present in a crystalline state, have poor permeability to the skin. Therefore, non-aqueous patches have a high concentration of lidocaine. It is pointed out that lidocaine has an adverse effect on the heart. Prolonged use of a high concentration of lidocaine causes side effects, such as shock, rubor, and irritating sensation. External preparations comprising more than 5 mass % of lidocaine are designated as powerful drugs, and cannot be used as household (nonprescription) medicine. Provided is a non-aqueous patch that is effective to relieve muscle pain, the non-aqueous patch comprising lidocaine and/or its reactant, and a dissolving agent composed of an organic acid and a polyalcohol, which are contained in a base.
