Problematic Use of Buspirone and Tandospirone: A Scoping Review. (PubMed, J Addict Med) - "Findings highlight a discrepancy in the primary literature. Specifically, experimental studies conclude that so far, buspirone and tandospirone have a low potential for problematic use. However, more recent case reports document instances of nonprescribed buspirone misuse, particularly among individuals with a history of incarceration or SUD, possibly stemming from a complex interplay of biopsychosocial-behavioral rather than purely pharmacological factors. Further research is needed to guide strategies for preventing problematic azapirone use while ensuring effective anxiety treatment in high-risk populations."

Autism spectrum disorder-like behaviors induced by hyper-glutamatergic NMDA receptor signaling through hypo-serotonergic 5-HT1A receptor signaling in the prefrontal cortex in mice exposed to prenatal valproic acid. (PubMed, Neuropsychopharmacology) - "Treatment with a low-affinity NMDA receptor antagonist (memantine), a selective 5-HT reuptake inhibitor (fluoxetine), and a 5-HT1A receptor agonist (tandospirone) attenuated both the increase in CaMKII phosphorylation and ASD-like behavior of prenatal VPA mice. WAY-100635-a 5-HT1A receptor antagonist-antagonized the effect of fluoxetine on impaired social behavior and object recognition memory. These results suggest that E/I imbalance and ASD-like behavior are associated with hypo-serotonergic receptor signaling through 5-HT1A receptors in prenatal VPA mice."

Ameliorating effect of chotosan and its active component, Uncaria hook, on lipopolysaccharide-induced anxiety-like behavior in mice. (PubMed, Front Pharmacol) - "Furthermore, treatment with tandospirone, a 5-HT1A receptor agonist, alleviated anxiety-like behavior in mice, whereas treatment with DOI, a 5-HT2A receptor agonist, enhanced anxiety-like behavior in mice...These findings indicate that chotosan exerts anxiolytic-like effects in the context of inflammation-induced anxiety, potentially mediated by the inhibition of 5-HT2A receptor hyperfunction in LPS-treated mice. Consequently, we postulate that chotosan may be effective in managing inflammation-induced anxiety-like behaviors."

Neonatal hypoxia impairs serotonin release and cognitive functions in adult mice. (PubMed, Neurobiol Dis) - "Finally, chronic treatment of adult MPA mice with fluoxetine, an inhibitor of 5-HT reuptake transporter, or the 5-HT1A receptor agonist tandospirone rescues cognitive flexibility and memory impairments. All together, these data demonstrate that the development of 5-HT system function is vulnerable to moderate perinatal asphyxia. 5-HT hypofunction might in turn contribute to long-term cognitive impairment in adulthood, indicating a potential target for pharmacological therapies."

Augmentation therapy with serotonin receptor partial agonists on neurocognitive function in schizophrenia: A systematic review and meta-analysis. (PubMed, Schizophr Res Cogn) - "5-HT partial agonists (buspirone or tandospirone) did not have a significant effect on verbal learning (SMD = 0.08, 95 % CI = -0.31 to 0.47) or working memory (SMD = 0.15, 95 % CI = -0.09 to 0.39)...The absence of any significant benefits in the cognitive domains studied here may have been due to the variance in the concomitant medication (typical vs atypical antipsychotic drugs), the level of cognition at baseline, or other factors. Further studies with various types of 5-HT agonists are warranted to examine the potential cognitive efficacy of stimulating these receptors."

The Serotonin 1A (5-HT) Receptor as a Pharmacological Target in Depression. (PubMed, CNS Drugs) - "Stimulation of the 5-HT receptor is an existing therapeutic target for treating depression and anxiety, using drugs such as buspirone and tandospirone...The development of 5-HT 'biased agonism', using compounds such as NLX-101, offers the opportunity to further elucidate the roles of pre- and post-synaptic 5-HT receptors. We describe how experimental medicine approaches can be helpful in profiling the effects of 5-HT receptor modulation on the different clinical domains of depression, and outline some potential neurocognitive models that could be used to test the effects of 5-HT biased agonists."

5 - HT1A Receptor Agonists in the Treatment of Psychopathology and Cognitive Impairment of Schizophrenia; An Avenue to Disease - Modifying Therapy (CINP 2023) - "It is of note that SEP-363856, a non-D2-receptor-binding drug that selectively acts on 5-HT1A receptors, in addition to trace amine-associated receptors, has been shown to ameliorate psychotic symptoms...Specifically, up-to-date information will be provided on the recent meta-analysis to confirm beneficial effects of augmentation with buspirone or tandospirone, azapirone derivatives usually prescribed as anxiolytics, on positive symptoms and attention/processing speed. The advantage of such add-on therapy raises the possibility that some marketed antipsychotic drugs, e.g., brexpiprazole and lurasidone, show part of their antipsychotic and cognition-enhancing efficacy via. actions on 5-HT1A receptors. These considerations will help refine the strategy to overcome unmet needs (e.g., cognitive impairment) in the treatment of psychotic disorders, and promote further endeavor to develop novel pharmacotherapy."

Augmentation Therapy with 5 - HT1A Partial Agonists In Schizophrenia: A Meta - analysis (CINP 2023) - " Random-effects model meta-analyses revealed significant favorable effects on overall psychotic symptoms (SMD = -1.13, 95% CI = -1.98 to -0.27) and positive symptoms (SMD = -0.72, 95% CI = -1.31 to - 0.12) for add-on therapy with buspirone or tandospirone , while the effect on negative symptoms did not reach significance (SMD = -0.93, 95% CI = -1.90 to 0.04). These findings support the idea that some compounds that stimulate 5-HT1A receptors can provide an effective pharmacologic enhancer in the treatment of schizophrenia. Further clinical trials are warranted to determine the benefits of the adjunctive use of 5-HT1A partial agonists in ameliorating symptoms and improving functional outcomes in patients with schizophrenia."
