Abstract
Enteral pharmaceutical compositions containing medicinal agents having parenteral abuse potential are rendered resistant to aqueous extraction through the incorporation of a sufficient amount of a nontoxic, water gelable material. Attempts to extract the medicinal agent for parenteral abuse are thus inhibited or prevented since the material gels in the presence of water leaving no filterable liquid.
