The invention provides a pressure-sensitive adhesive composition for medical applications comprising a blend of at least two components comprised of about 5 to about 95% by weight of a first component comprised of at least one acrylic pressure-sensitive adhesive and about 5 to about 95% by weight of a second component comprised of either (a) at least one elastomer with a tackifying resin, or (b) at least one thermoplastic elastomer, wherein the resulting pressure-sensitive adhesive demonstrates a T.sub.0 of at least 1 N/dm and a T.sub.48 of less than 12 N/dm when adhered to skin. The pressure-sensitive adhesive composition is prepared either in the presence of a solvent or is alternatively prepared by melt blending. A method of preparing such an adhesive is also disclosed.
