Abstract

Objectives: The effectiveness of drugs currently used in medication, which is important in the treatment of alcohol use disorders, is limited. Recently, ondansetron which acts as 5-HT3 receptor antagonist, has been studied and proved possibility as new medication for alcohol use disorder. Meanwhile, there are studies supporting that 5-HT1A receptors are related to addictive behavior. Considering those studies, we expect that vortioxetine, which acts as both 5-HT3 receptor antagonist and 5-HT1A receptor agonist, may be effective in treatment of alcohol use disorder. The purpose of this study is to examine the effect of vortioxetine on alcohol intake of C57BL/6 mice.
Methods: In this study C57BL/6 mice were randomly assigned to normal saline group, vortioxetine 10 mg/kg group and vortioxetine 1 mg/kg group. To study effect of vortioxetine on alcohol, water, food intake and body weight of mice, we administered each medication for 14 days.
Results: The overall alcohol intake was different between the three groups (pGroup=0.021), and alcohol intake in vortioxetine 10 mg/kg group was significantly lower than one in placebo group. Change across time points (pTime<0.001) and the interaction between group and time (pGroup×Time=0.016) were also significant. However, there were no significant differences between the three groups in water, food intake and body weight.
Conclusions: These results indicated that administration of high dose vortioxetine reduced alcohol intake of mice. Therefore, it is necessary to conduct clinical studies to examine the effectiveness of vortioxetine as a new treatment for alcohol use disorder.
