1. A self-supporting film composition comprising:
- (i) a water soluble polymer composition comprising polyethylene oxide and a saccharide-based polymer; and
(ii) a topical agent;
wherein said topical agent is in the form of a small-scale particle selected from the group consisting of at least one type of nanoparticle, at least one type of micelle, at least one type of microdroplet, at least one type of microparticle, at least one type of liquid crystal, and combinations thereof, andwherein said small-scale particle of at least one agent is uniformly distributed in the film composition and uniformity is measured by equally sized individual unit doses which do not vary by more than 10% by weight of said small-scale particle of at least one agent from a desired dose.

Abstract
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. Desirably, the films contain at least one active agent, which may be administered to a user topically, transmucosally, vaginally, ocularly, aurally, nasally, transdermally or orally.
