Abstract
The invention relates to film products containing desired levels of active components and methods of their preparation. 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. Desirably, the films may be exposed to temperatures above that at which the active components typically degrade without concern for loss of the desired activity.
