摘要：
A Delivery System for delivery of an Active Component is provided. The Delivery System comprises a Delivery Matrix and an Active Component. The Delivery Matrix has one or both of (i) a Cationic Component； and (ii) a Matrix Forming Substance. The Cationic Component has one or both of: (i) a cationic polymer or cationic copolymer, and (ii) a positively charged non-polymeric compound or composition. The Active Component comprises a cationic bioactive. The Delivery Matrix has a mEq amount of positive charge which is equal to or exceeds the mEq amount of positive charge of the Active Component. The Delivery Matrix may comprise chitosan, or other biopolymers, synthetic polymers, matrix polymers and large molecules, which themselves are matrix forming, or are combined with a Matrix Forming Substance and one or more other Cationic Components to form the positively charged Delivery Matrix.
