Patent number: 5744166Abstract: Compositions for delivery of pharmacologically active agents and methods for their administration are provided. In one embodiment, the compositions include a complex of a polycationic polymer and a pharmacologically active agent in a pharmaceutically acceptable carrier. The compositions in one embodiment permit transport of pharmacologically active compounds across mucosal membranes for systemic delivery. The polycationic polymer may be, for example, a polycationic carbohydrate such as a chitosan or a chitosan salt or derivative. The therapeutic agent a preferred embodiment is a vaccine or a nucleic acid, such as a gene or antisense oligonucleotide. The composition may be provided in different forms such as a solution, dispersion, powder or in the form of microspheres.Type: GrantFiled: December 21, 1995Date of Patent: April 28, 1998Assignee: Danbiosyst UK LimitedInventor: Lisbeth Illum

Patent number: 5709876Abstract: The present invention is a saccharide-based matrix, and the products resulting therefrom, made from a maltodextrin feedstock subjected to conditions which induce flash flow of the maltodextrin so that the matrix possesses a physically or chemically altered structure from the feedstock. The present invention also includes a method of producing the matrix and of making products which take advantage of the unique properties of the matrix.Type: GrantFiled: June 7, 1995Date of Patent: January 20, 1998Assignee: Fuisz Technologies Ltd.Inventor: Richard C.

Patent number: 5700478Abstract: Water-soluble pressure-sensitive adhesives include a water-soluble polymer that is made tacky at room temperature by addition of a water-soluble plasticizer that is miscible with the polymer. Suitable polymers are solid at room temperature; and have a hydrophilicity as measured by water uptake greater than about 25%; they are liquid at room temperature and have a boiling point higher than about 80.degree. C. The adhesives according to the invention may conveniently be provided in dry film form. Preferred water-soluble pressure-sensitive adhesives of the invention adhere both to mucosal surfaces and to a variety of materials that may constitute a part of a device or prosthesis to be held in a body cavity that has a mucosal lining. Also, a laminated device for the controlled release of a substance within a mucosa-lined body cavity includes the substance dissolved or dispersed in either or both of a water-soluble pressure-sensitive adhesive layer and optionally one or more water-soluble polymer layers.Type: GrantFiled: August 3, 1995Date of Patent: December 23, 1997Assignee: Cygnus, Inc.Inventors: James E. Biegajski, Subbu S. Venkatraman, Ann M. Scott
