DRUG DELIVERY DEVICES

摘要

Drug delivery devices and techniques are described for use in treatment of periodontal disease and the like. The delivery device includes benzo (c) phenanthridine alkaloid in a bioerodable and biocompatible material. The alkaloid is slowly released from the bioerodable material in the oral cavity. The bioerodable material may be polymeric and may be natural or synthetic. The delivery device may be inserted subgingivally (e.g., in a periodontal pocket) where the alkaloid is released slowly over a period of days.
