The analgesia afforded by SCS\/PNS may be enhanced or attenuated by the ongoing use of analgesic medications that are often consumed by patients who receive SCS and PNS implants. We undertook a scoping review to scan and summarize the evidence for impact of adjuvant pharmacotherapy on SCS and PNS therapy in animal and human settings.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods<\/jats:title>\n                    <jats:p>A comprehensive medical literature review was performed on major medical databases including MEDLINE, EMBASE, CINAHL, CENTRAL, and Google Scholar from inception until July 31, 2024, for both human and animal studies.

In human studies, SCS non-responders with neuropathic pain had analgesia restored by addition of intrathecal baclofen and clonidine. Patients who eliminated opioid use, or who were opioid naive, had superior clinical outcomes with SCS compared to those continuing opioids. Cannabinoids were associated with enhanced SCS analgesia. Patients on benzodiazepines had higher likelihood of SCS explantation. Animal studies showed intrathecal ketamine restored SCS analgesic benefits, while baclofen, clonidine, cannabinoid receptor agonists, tricyclic antidepressants, serotonin, and norepinephrine reuptake inhibitors, augmented SCS responses while benzodiazepines were found to inhibit analgesic effects of PNS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This review indicates that adjunctive analgesic therapy may play a significant role in either enhancing or attenuating analgesic benefits from SCS and PNS.
