Used as a non-opioid analgesic for the management of moderate to severe pain. It is commonly prescribed postoperatively or for acute pain conditions where opioid use is not preferred. Works centrally by inhibiting the reuptake of serotonin, norepinephrine, and dopamine, contributing to its pain-relieving effects. Often used as an alternative to opioids due to lower risk of respiratory depression and addiction. Also utilized in some cases for treating shivering during anesthesia or surgery. Available in oral and injectable forms for flexible dosing in clinical settings.
