Narcotics are widely used as the mainstay of pain treatment, although increasing doses are required over time as the individual becomes tolerant to their effects. This can lead to the development of dependence and abuse of these drugs. Research has identified a new way to decrease the risk of developing tolerance to narcotics, by giving at the same time a drug called rotigotine ("Neupro"). Rotigotine interferes with the body's chemical dopamine and is FDA-approved for the management of Parkinson's Disease. The purpose of this research study is to look at side effects and pain control in healthy people after removal of wisdom teeth, which usually causes pain. It is thought that by giving the study drug rotigotine with the narcotic pain reliever, there will be pain control that will extend longer than when giving the narcotic alone.
