COMPOSITION FOR TRANSDERMAL OR TRANSMUCOSAL ADMINISTRATION

摘要

[PROBLEMS] To provide a composition for transdermal or transmucosal administration which is useful as an anti-Alzheimer's disease drug, an anti-Parkinson's disease drug, an antidepressant drug, a psychotropic drug, a remedy for drug dependence or the like. [MEANS FOR SOLVING PROBLEMS] A composition for transdermal or transmucosal administration, which contains an effective amount of a racemic body or optically active isomer of 1-(benzofuran-2-yl)-2-propylaminopentane or its pharmacologically acceptable salt and a vehicle and can be administered without invading the skin or mucosa, is excellent as an anti-Alzheimer's disease drug, an anti-Parkinson's disease drug, an antidepressant drug, a psychotropic drug or a remedy for drug dependence, since the composition enables the stable accession of an effective amount of the active ingredient into the body or brain via the skin or mucosa without causing any trouble such as a loss in the active ingredient due to the first pass effect in the liver, a pain, an injury or infection.
