Abstract

Background: Chronic stress can lead to anxiety and depression. Escitalopram is a selective serotonin reuptake inhibitor (SSRI), and crocin is a natural compound derived from saffron. Both of them are used to treat these disorders in clinical and traditional medicine, respectively. This study compared the antidepressant and anxiolytic effects of escitalopram, crocin, and their combination in rats. Materials and Methods: Rats were divided into nine groups: control, sham, rest‑depression, depression‑rest, depression‑crocin, depression‑escitalopram10, depression‑escitalopram20, depression‑escitalopram10‑crocin, and depression‑escitalopram20‑crocin. Forced swimming and open field tests (FST and OFT, respectively) were used to evaluate depression, anxiety, and locomotor activity. Results: In the FST, the immobility time on day 28 significantly decreased in all depressed groups that received escitalopram, crocin, and their combination compared to the rest‑depression group. Whereas, conversely, the time spent at the center in the OFT was significantly higher in similar comparisons. The total distance traveled by the OFT was significantly lower in all depressed groups, except for the depression‑escitalopram10 and depression‑escitalopram20 groups. The total distance traveled was significantly higher in the depression‑escitalopram20 compared to the rest‑depression group. Conclusion: Crocin, both doses of escitalopram and their combination, reduced depression. A high dose of escitalopram, with and without crocin, was partially more effective than a low dose of escitalopram in reversing depression. There was anxiety‑like behavior observed after inducing depression with and without a recovery period. Whereas, crocin alone and both doses of escitalopram, with and without crocin, decreased anxiety‑like behaviors in subjects with depression. This effect may be attributed to a modulation of brain neurotransmitter ratios. © 2024 Advanced Biomedical Research.
