The common analgesic, morphine, has a narrow therapeutic window and numerous side effects.1 Ketamine, is a chemically stable compound, non-opioid with analgesic properties at low doses. In addition, ketamine stimulates the cardio-respiratory system which is of great benefit in injured patients.2-4 Ketamine is generally administered by the intravenous (IV) route and provides analgesia via antagonism of the N-Methyl-D-Asparate (NMDA) receptor. Ketamine has the added benefit of a wide therapeutic safety index. IV ketamine has been shown to provide postoperative analgesia in many clinical trials; in particular to reduce opioid consumption.5 Severe acute pain has been shown to progress to chronic pain due to central sensitization.6 Perioperative IV ketamine has been shown in limited studies to decrease the incidence of chronic pain after surgery. However, the IV route of administration of ketamine has limitations due to difficulties with IV placement in certain tactical situations. Therefore, the use of oral ketamine (non-opioid) for the purpose of acute pain management after trauma or surgery is highly desirable.
