If lidocaine is composed of non-aqueous patch, the adhesive power of the preparation tends to get lower, as the composition amount of lidocaine is higher. It is popular to solve lidocaine in dissolving agent in order to compose lidocaine in patch and release effective amount into skin. However, if the amount of dissolving agent gets higher, the adhesive power gets extremely lower, so that an long-time attachment is difficult. For solving this problem, a non-aqueous patch is provided comprising lidocaine and/or its reactant, and a dissolving agent which are contained in a base of plaster, the plaster being held by a support, of which strength of 50% stretched to longitudinal direction is less than 2,000g/50mm and of biaxially-oriented stretch cloth. |
