My Dr. Just Recently Prescribed Me Zubsolv As A Pain

My Dr. just recently prescribed me Zubsolv as a pain management from Suboxone. Has anyone heard of either of these used for pain as well as opiate addiction? I was on opiate based medication for 6 months before this. I don't feel any pain relief at all, yet my Dr. says these medications are used as pain management. I need help with the pain, not addiction.
