The invention provides pharmaceutical compositions comprising macromolecular gastrointestinal enzyme-labile opioid prodrugs, co-formulated with small-molecule and/or macromolecular gastrointestinal enzyme inhibitors.

An optional macromolecular opioid antagonist may also be present in compositions of the invention to discourage tampering by potential abusers.
