Brief Summary: The treatment of resistant depression should be optimized aiming at complete remission of symptoms, a complex condition due to several factors. Approximately 1/3 of patients with depressive disorders do not even respond to available antidepressants. Consequently, new molecules with robust action, fast effects and sustained improvement are currently being researched worldwide. Ketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist, has emerged as a promising alternative due to its involvement in neurogenesis, synaptogenesis and consequent rapid improvement of depressive and suicidal symptoms with traditional intravenous (IV) use in sub dose (0.5 mg / kg). The therapeutic response of IV use has been short and requires monitoring in a hospital setting. There are no studies evaluating response to long-term ketamine use. Recent research has focused on identifying other routes of ketamine use such as intranasal and intramuscular (IM). The use of ketamine IM, despite the fact that there are few studies and small samples, can demonstrate efficacy in acute treatment and maintenance of depression, as well as low profile of side effects, greater accessibility potential, reduced costs and risks, patient comfort and possible expansion of resistant depression treatment capabilities in different settings.
