Ketamine produces a rapid antidepressant effect, but its use can be associated with serious side effects. Hence, other therapeutic options that will allow us to obtain a quick and safe antidepressant effect by modulating glutamatergic transmission are needed. Antagonists of mGlu2/3 receptors, which share some mechanisms of action with ketamine, may be good candidates to obtain this effect....
Ketamine has been shown to induce a rapid antidepressant effect on patients with depression. In many animal models, both rapid and sustained antidepressant activities were also found in response to an antagonist of group II metabotropic glutamate receptors, LY341495, and its mechanism of action seemed to be similar in many ways to the action of ketamine. It has also been found that LY341495...
