ABSTRACT:
The present invention provides a percutaneous absorption preparation which comprises a skin contact base containing therein at least one active ingredient selected from the group consisting of biperiden, trihexyphenidyl and pharmacologically acceptable salts thereof in an amount of from 0.5 to 60% by weight. The percutaneous absorption preparation makes it possible to permit the percutaneous absorption of biperiden, trihexyphenidyl or pharmacologically acceptable salt thereof as an active ingredient so that the medicament can be used effectively and at the same time, pharmacological effects can be sustained long and administration can be carried out conveniently. In addition, the active ingredient contained in it can be maintained stably.
