This review will focus on three drugs commonly infused as intravenous co-analgesics” Hutchins and Rockett (2019).
Atypical analgesics include antiepileptics and other membrane stabilizers (lidocaine and mexilitine), antidepressants, alpha-2-noradrenergic agonists, N-methyl-d-aspartate (NMDA) antagonists, corticosteroids and cannabinoids. This review will focus on three drugs commonly infused as intravenous co-analgesics. We will review the theoretical mechanisms of action, efficacy and clinical effectiveness of lidocaine, ketamine and magnesium. The evidence base supporting their use has expanded in recent years and is discussed below.
