Abstract
The present invention provides an adhesive preparation superior in adhesion property, which does not peel off or fall off easily and which can be adhered for a long time. An adhesive preparationhas a supportmade of a cloth, and a pressure sensitive adhesive layerformed on one surface of the support, which contains a pressure sensitive adhesive and a drug. The ratio (CW/AW) of a mass (CW) per unit area of the supportand a mass (AW) per unit area of the pressure sensitive adhesive layeris 1.0-5.0, an adhesive layer-free surface of the supporthas a static friction coefficient of 0.25-0.75, and a 20% modulus (AM) in one direction of the adhesive preparationand a 20% modulus (EM) in the direction perpendicular to that direction are each 0.5-1.5 N/cm, and the ratio thereof (AM/EM) is 0.5-2.0.
