Collagen troches for treating mouth lesions

Abstract

A soluble/erodable troche for delivering collagen in the mouth for treatment of mouth lesions. The collagen may be gelatin from animal skins. The structure of the troche may be formed with a porous network that remains solid at human mouth temperatures and slowly dissolves/erodes in saliva. In some embodiments, the network is elasto-plastic and in some cases it is hydrophilic. The collagen is located within pores of the network. The troche may be formed by mixing and hydrating the ingredients, bringing them to above an activation temperature below boiling, and cooling them to form a gel. The hot mixture may be poured into molds, including a flat sheet, and the mold may also serve as packaging for delivery. The packaging may comprise a germ barrier moisture passing film which allows the troche to dry out or become re-hydrated without growing mold.
