Abstract
Anxiety and Depression disorders are prevalent and severe diseases with deleterious impacts on patients and society. Selective serotonin reuptake inhibitors (SSRIs) were shown to be effective in treating a broad spectrum of anxiety and depression disorders. Despite their therapeutic actions, SSRIs are associated with a wide variety of side effects, such as weight changes, insomnia, gastrointestinal disturbances, and sexual dysfunction. Furthermore, recent studies show that their success rates are not high, reaching 50%. Therefore, there is a clear need to explore alternative treatments for anxiety and depression disorders. We have recently produced a novel herbal mixture to treat anxiety disorder. The novel treatment displayed anxiolytic and antidepressant-like effects in treated mice previously exposed to stress. The present study aimed to examine whether the novel treatment induces two common side effects normally induced by the conventional treatment with the SSRI escitalopram, namely, sexual dysfunction and weight gain. Mice were treated with either (a) herbal treatment, (b) one of the four herbal components, (c) escitalopram, or (d) control group. Following treatment, sexual behavior and weight gain were evaluated in the different groups, as well as changes in prefrontal cortex serotonin transporter levels. We have found that the novel treatment has not altered sexual behavior and did not cause weight gain, while escitalopram did lead to these two side effects. Recently, we discovered that NHT has one dominant herb component (Crataegus Pinnatifada ), which has the same antidepressant and anxiolytic effects with minimal side effects.
These results suggest that the novel treatment may have the same behavioral anxiolytic and antidepressant efficacy as SSRIs while causing fewer side effects, possibly due to different biological mechanisms. Further studies are now conducted to explore the underlying biological mechanisms through which the novel treatment leads to the behavioral anxiolytic and antidepressant effects.
