Polarization controlled release of the pharmacology activated molecule which electric charge does just from the matrix which includes the polymer which possesses the oxygen atom which is done

摘要

An oral pharmaceutical composition, comprising one or more positively charged, highly water-soluble pharmaceutically active agents such as trospium chloride, and one or more polymers containing polarized oxygen atoms, whereby the active agent(s) form an ion-dipole interaction with the polymer(s) that may be used for an immediate release system, an extended release system or a delayed release system.
