Abstract

This invention is directed to a superior adhesive for oral adhering discs or troches. The adhesive is at least 80% acacia gum mixed with calcium carbonate so that, as the acacia gum is combined with water, it does not yield a pH lower than 5.5. The preferred ratio of acacia gum to calcium carbonate is within the range 15:1 to 50:1.

Claims (9)

1. A method of making an adhering troche having two sides that, when held in a human mouth, adheres and remains in the mouth as a single item that does not smear or break apart, comprising,

(a) pressing a powder comprising an ingredient to be released into saliva to form a layer, roughly disc-shaped and having a roughly flat side at least 5 mm in two dimensions;

(b) pressing granules of powder where a plurality of the granules each contains particles of both acacia gum and calcium carbonate that are granulated together to form an adhesive layer, roughly disc-shaped and having a roughly flat side at least 5 mm in two dimensions,

wherein the granules of powder comprises at least 80% acacia gum mixed with a sufficient quantity of calcium carbonate such that the pH of the mixture is 5.5 or higher when dissolved in 10 parts water; and

wherein the two layers are pressed together leaving one side of each layer exposed such that one side of the resulting troche is adhesive and the other side of the resulting troche is not adhesive.

2. The method of claim 1 , wherein the granules of powder are made by wet mixing particles of calcium carbonate with particles of acacia gum and the resulting mixture is then dried into granules.

3. The method of claim 1 wherein the adhesive layer adheres to a roof of a mouth of a human strongly enough to hold triple the weight of the troche against force of gravity.

4. The method of claim 1 wherein the adhesive layer adheres to a roof of a mouth of a human strongly enough to hold the weight of the troche plus an additional 680 milligrams against force of gravity.

5. The method of claim 1 , wherein the pressing is performed with a bi-layer tablet press.
