Abstract
Drug preparations for external application having a stick-itself-to-the-skin property, so-called 'soft patch', are provided. The preparations contain a drug, a water-soluble protein having an absorption-promoting effect, a polyhydric alcohol a tackifier, and an oleaginous substance, and ensure an improved percutaneous absorption and bioavailability of the drugs, thus permitting an accurate control of drug dosage.
