“…Opioids and non-steroidal antiinflammatory drugs are commonly used to treat postoperative pain [2], however, these drugs may increase the risk of respiratory depression and postoperative bleeding, respectively [3]. In contrast, acetaminophen (paracetamol) is a non-opioid analgesic that is devoid of these risks [3], and its enteral formulation has been used alone [4] and as an adjunct to other agents in the management of postoperative pain [5]. However, the efficacy of enteral acetaminophen as a stand alone analgesic has been hampered by its delayed absorption [6] and sub-therapeutic plasma concentrations [3,7] which have made this form of analgesia less than ideal in the immediate postoperative period [3,4].…”
