Abstract
A drug preparation applicable to the oral mucosa is disclosed, comprising a soft adhesive film containing a systemic drug, the adhesive film comprising a homogeneous mixture comprising a vinyl acetate homopolymer, an acrylic acid polymer, and a cellulose derivative capable of being dissolved in or swollen with water and a lower alcohol. The drug preparation is less causative of an adverse feeling in the oral cavity on use, excellent in shape retention on water absorption, and adhesive to the oral mucosa for an extended period of time, thereby achieving a stable administration of a systemic drug for a long time.
