摘要:
The invention refers to a composition material that is intended for rapidtransmucosal delivery in the mouth of a biologically active substance when incontact with saliva. The composition material comprises at least one ioniccarbohydrate, having at least one biologically active substance ionicallybound thereto, and at least one wetable non-soluble polymeric carbohydrate.The invention also refers to a method of preparing the composition material,which comprises the steps of: (a) providing a mixture of the at least onebiologically active substance and at least one ionic carbohydrate in a solventhaving a permissive pH for ionic bonding of the at least one biologicallyactive substance to the at least one ionic carbohydrate (b) mixing themixture in the solvent for a period that is sufficient for allowing the ionicbonding to take place and (c) recovering the mixture from the solvent.
