Ketamine, a fast-acting antidepressant, is a racemic mixture, composed of equal amounts of R- and S-ketamine. Preclinical studies are comparing them to better understand their role in therapeutic and undesirable effects. An important research gap is that studies do not use long clinically relevant protocols to compare the desired and undesired effects of ketamine enantiomers in modeled and...
Ketamine has gained significant attention as a fast-acting antidepressant. However, ketamine is also associated with undesirable side effects. In our preclinical study, we explored the behavioral effects of ketamine enantiomers at subanesthetic doses. During repeated intermittent treatment, we examined locomotor stimulation and sensitization, ataxia, and expression of natural behaviors...
