The objective of this study was to evaluate the behavioral response of ayahuasca in rats submitted to neuro­ inflammation through the intraperitoneal application of lipopolysaccharide (0.63 mg/kg/mL). Eighty animals, male, about 90 days old, were divided into control and LPS groups and later into prevention and treatment subgroups. The prevention subgroup was administered ayahuasca or saline solution, via gavage, at a dose of 4 mL/kg one hour before applying LPS or saline, while the treatment subgroup received the same dose of the respective substances 24 h after intraperitoneal applications. Behavioral parameters were evaluated using open field (anxiety-like) and forced swimming (depressive-like) tests. A decrease in LPS/AYA rats in the prevention and treatment subgroups regarding anxiety-like behavior was observed. As for the depressive-like behavior, there was a decrease in the group induced to the disease model, both in the prevention subgroup (when compared to the SAL/SAL, SAL/AYA, and LPS/AYA with LPS/SAL groups) and in the treatment (when comparing SAL/SAL and LPS/AYA with LPS/SAL). This study concludes the anxiolytic and antidepressant potential of ayahuasca in an animal model of neuroinflammation, possibly due to the antineuroinflammatory effects already reported of the compound.
