    摘要: The invention relates to the film products and methods of their preparation that demonstrate a non-self-aggregating uniform heterogeneity. Desirably, the films disintegrate in water and may be formed by a controlled drying process, or other process that maintains the required uniformity of the film. The films contain a polymer component, which includes polyethylene oxide optionally blended with hydrophilic cellulosic polymers. Desirably, the films also contain a pharmaceutical and/or cosmetic active agent with no more than a 10% variance of the active agent pharmaceutical and/or cosmetic active agent per unit area of the film.

    摘要: The present invention is a method of preparing a system for delivering a bio-affecting agent and the composition prepared thereby. The invention includes forming a molecular dispersion of the bio-affecting agent in an increased energy state in a water-soluble polymer which is compatible with the bio-affecting agent. As a consequence of transforming the bio-affecting agent to an increased-energy condition and freezing it in such condition in a water-soluble polymer, the bio-affecting agent is made available (“bio-available”) to a bio-system upon dissolution of the polymer. This method and composition has been found extremely effective for delivery of otherwise substantially non-soluble drugs and other bio-affecting ingredients.
