| Abstract: | This systematic review aims to elucidate the nexus between ketamine's psychoactive properties and its efficacy in treating a broad spectrum of psychiatric disorders. We searched three databases and used citation tracking to include 29 studies. Predominantly, mood disorders, including bipolar disorder (BD) and major depressive disorder (MDD) (MDD + BD: + n = 25 studies), a large part of them involve treatment-resistant patients (n = 14 studies), substance use disorder (SUD, n = 3 studies), and social anxiety disorder (SAD, n = 1 study). From all included studies (n = 29), 15 (51.72%) of them identified a positive relation between ketamine-induced altered states of consciousness and clinical outcomes, while 13 studies (44.83%) showed no linkage between them, and one study (3.45%) delineated a negative association. Focusing solely on intravenous (IV) ketamine infusions (n = 25), 14 studies (56%) reported a positive modulation of ketamine's psychoactive effects and therapeutic benefits, whereas 10 studies (40%) confirmed no relationship, and one study (4%) showed a negative association. The single study (33.34%) involving subcutaneous ketamine and all three studies (66.6%) intranasal administration did not demonstrate a significant interaction between ketamine's psychoactive effects and therapeutic response. All three SUD studies reported a positive correlation between ketamine's psychoactive effects and therapeutic response. In contrast, the single SAD study did not find a relationship between these parameters. For studies involving mood disorders (n = 25), 12 studies (48%) reported a positive relationship between psychoactive effects and therapeutic response. Others 12 studies (48%) identified a null relationship, and one study (4%) found a significant negative association. Although we have found a larger association than previous studies between ketamine's psychoactive properties and its efficacy in treating a broad spectrum of psychiatric disorders, its topic remains indeterminate, mainly due to the high heterogeneity.
