Pharmaceutical compositions and their methods of use are provided, where the pharmaceutical compositions comprise a phenol-modified opioid prodrug that provides enzymatically-controlled release of a phenolic opioid, and an enzyme inhibitor that interacts with the enzyme(s) that mediates the enzymatically-controlled release of the phenolic opioid from the phenol-modified opioid prodrug so as to modify enzymatic cleavage of the phenol-modified opioid prodrug. |
