Abstract:
An article of manufacture comprising a monolithic composition formed by combining at least the following components: at least about 20% by weight of a polymer having a solubility in water below about 0.1% at 25.degree. C. and atmospheric pressure; between about 10% to about 70% by weight of a hydrophilic agent having a solubility in water above about 1% at 25.degree. C. and atmospheric pressure; and at least about 5% by weight of a desiccating agent;wherein at least the hydrophilic agent is heated above its melt point in combination with the polymer and desiccating agent;wherein the percent by weight of each component is based on the total weight of the three components;wherein the desiccating agent is substantially distributed within the hydrophilic agent; andwherein the hydrophilic agent is substantially distributed in channels within the polymer.
