Nalbuphine (NLB) is a kappa-agonist and mu-partial antagonist, widely used for opioid withdrawal de-addiction, opioid-induced pruritis and as emergent analgesia. ⋯ The submental route of NLB is faster, more efficacious than the intramuscular route. Thus, we conclude that in the case of emergent scenarios (i.v or i.m. route is compromised), where immediate relief is necessary, the submental route is a preferred choice.
