EP0274431A2 — Drug delivery compositions and methods

USPTO Abstract

Drug delivery compositions yield new and unexpected degrees of stabilization, solubilization and delivery of incorporated medicaments, drugs, or other physiologically-active compounds. The composi­tions enable administration of drugs and other medic­ally useful compounds via a variety of routes. More particularly, a drug delivery system or composition including one or more monomeric or polymerized sur­face active agents allows for rapid dissolution and smooth liberation of any desired incorporated drug or combinations, and the method of preparing the drug composition. In one embodiment, the physiologically-­active compound is encapsulated by a coacervate-derived film, and the finished product is suitable for trans­mucosal administration. Other formulations of this invention may be administered via inhalation, oral, parenteral and by transdermal routes.
