Abstract
The present invention provides an oral dosage form comprising a first composition and a second composition. The first composition comprises an effective amount of a therapeutic agent and the second composition comprises an effective amount of an adverse-effect agent. The adverse-effect agent is covered with a coating that is substantially insoluble in the gastrointestinal tract. In one embodiment, the adverse-effect agent is coated with an outer base-soluble layer and an inner acid-soluble layer. The therapeutic agent can be uncoated or can be coated with a coating having an outer acid-soluble layer and an inner base-soluble layer. The dosage form discourages administration of the therapeutic agent by other than oral administration.
