Disclosed is a medicated patch comprising a medicinal agent, an adhesive base material and an adhesiveness-imparting agent, wherein the medicinal agent is varenicline or a pharmaceutically acceptable salt thereof, the adhesive base material is a rubbery adhesive base material, and the adhesiveness-imparting agent is an rosin-type adhesiveness-imparting agent selected from the group consisting of rosin, a rosin derivative and a hydrogenated product of rosin or the rosin derivative or a non-rosin-type adhesiveness-imparting agent selected from the group consisting of an aliphatic hydrocarbon resin and an alicyclic hydrocarbon resin. When a non-rosin-type adhesiveness-imparting agent is used as the adhesiveness-imparting agent, the medicated patch further contains a solubilizer for the medicinal agent, wherein the solubilizer comprises an alcohol-type solubilizer having at least a solubility parameter of 20 to 35.
