Abstract

An ingestible compositions includes a first polymer layer, an adhesive layer associated with the first polymer layer, where the adhesive layer includes an adhesive material and is configured to releasably adhere to the first polymer layer, an alginate layer adhered to the adhesive layer, and a second polymer layer associated with the alginate layer and configured to releasably adhere to the alginate layer. Aspects further include methods of making and using the compositions.

First claim

What is claimed is:

1. An ingestible composition comprising:
a first polymer layer;
an adhesive layer associated with the first polymer layer, the adhesive layer comprising an adhesive material and configured to releasably adhere to the first polymer layer, wherein the adhesive layer comprises hydropropyl-cellulose, povidone, glycerine, and dehydrated ethanol, and wherein:
the hydropropyl-cellulose has a formulation weight of about 22.1% and a dry weight of about 83.33%;
the povidone has a formulation weight of about 2.2% and a dry weight of about 8.33%;
the glycerine has a formulation weight of about 2.2% and dry weight of about 8.33%; and
the dehydrated ethanol has a formulation weight of about 73.5%;

an alginate layer adhered to the adhesive layer; and
a second polymer associated with the alginate layer and configured to releasably adhere to the alginate layer.

2. An ingestible composition comprising:
a first polymer layer;
an adhesive layer associated with the first polymer layer, the adhesive layer comprising an adhesive material and configured to releasably adhere to the first polymer layer;
an alginate layer adhered to the adhesive layer, wherein the alginate layer comprises sodium alginate, sorbitol, glycerine, and purified water, and wherein:
sodium alginate has a formulation weight of about 3.4% and a dry weight of about 81.3% or has a formulation weight of about 0.38% and a dry weight of about 10.6%;
sorbitol has a formulation weight of about 0.08% and a dry weight of about 2.3%;
glycerine has a formulation weight of 0.20% and a dry weight of about 5.7%; and
purified water has a formulation weight of about 95.92%; and

a second polymer layer associated with the alginate layer and configured to releasably adhere to the alginate layer.
