Abstract:
1. A process for making an ingestible film having a substantially uniform distribution of components and a desired level of a pharmaceutical or biological active component, comprising the steps of: (a) combining a polymer component, water and a pharmaceutical or biological active component to form a matrix with a uniform distribution of said components; (b) forming a film from said matrix; (c) providing a conveyor surface having top and bottom sides; (d) feeding said film onto said top side of said surface; and (e) drying said film within about 10 minutes or fewer by applying hot air currents to said bottom side of said conveyor surface with substantially no hot air currents on the top side of said surface and exposing said film to a temperature above a degradation temperature of said pharmaceutical or biological active component, wherein said degradation temperature is 70° C. or higher, wherein said pharmaceutical or biological active component is maintained at said desired level.
