Plant Alkaloids for the Treatment of Depression



Abstract (as presented by the authors of the scientific work):

"Depression is a heterogeneous mood disorder that has been classified and treated in a variety of ways. Although, a number of synthetic drugs are being used as standard treatment for clinically depressed patients, but they have adverse effects that can compromise the therapeutic treatments and patient's compliance. Unlike, synthetic medications, herbal medicines are widely used across the globe due to their wide applicability and therapeutic efficacy associated with least side effects, which in turn has initiated the scientific research regarding the antidepressant activity. This review is mostly based on the literature of the last decade, aimed at exploring the preclinical profile of plant-based alkaloids (the abundant secondary metabolite) as an emerging therapy for depression."

Conclusion (as presented by the authors of the scientific work):

"Our review on the basis of available literature suggested that alkaloids could play a potential role as natural antidepressants. Keeping in mind their abundance in nature, the alkaloids could be an economical source of healing the depressive disorder. The available therapeutic agents fail to produced effect in all patients; approximately 30–40% failure has been reported to first-line antidepressant drugs accompanied by the very slow onset of action. Several alkaloids are in clinical practice and producing outstanding results in different therapeutic classes. These reported alkaloids though evoked antidepressant effects in various animal studies, but still deficient in clinical evidence. In conclusion, enough scientific evidence gathered in our review supported that the plant-based alkaloids can serve as leads for antidepressant drug discovery. It is key to subject these alkaloids to further clinical studies for efficacy, potency, and safety to ensure their clinical status."
