ABSTRACT:
An adhesive tape preparation of clonidine is disclosed, comprising a polytetrafluoroethylene porous sheet having an air permeability of from 10 to 500 seconds having thereon an active ingredient-containing layer comprising a pressure-sensitive adhesive obtained by copolymerizing a monomer mixture comprising from 40 to 80% by weight of 2-ethylhexyl acrylate, from 20 to 60% by weight of 2-methoxyethyl acrylate, and 0 to 40% by weight of vinyl acetate, the pressure-sensitive adhesive containing clonidine as an active ingredient. The preparation achieves sustained release of clonidine and exhibits long-term preservability while minimizing skin irritation and maintaining sufficient adhesion to the skin.
