Abstract

Introduction: Dexamethasone is a synthetic glucocorticoid with possible effects on ANXIETY and DEPRESSION because it has direct effects on the hypothalamus-pituitary-adrenal (HPA) and interacts with several neurotransmitter systems such as GABA and glutamate.Methods: Levels of ANXIETY and DEPRESSION in RATs were measured 40 minutes and 24 hours, respectively, after subcutaneous injection of Dexamethasone Sodium-Phosphate (DEX) 0.5, 1, 5, 10, 20, 30 mg/kg (saline 1ml/kg) in the elevated plus maze and forced swimming test.Results: The results of ANXIETY test showed a significant decrease in the percentage of open arm time and open arm entries in DEX (1 mg/kg) group compared to the saline groups. The percentage of time spent in the open arms significantly increased in DEX (20mg/kg) compared to the saline group. In terms of locomotor activity (total number of open and closed arms), significant decrease was observed in DEX (1 mg/kg) compared to the saline group. Also, a significant difference between DEX 1 and 20 mg/kg groups was observed. Comparative assessment of DEPRESSION during total immobility time showed significant increase in DEX (1 mg/kg) compared to saline and also a significant decrease was observed in DEX (30 mg/kg) compared to the saline groups. A significant difference in latency to immobility was also detected between DEX 1 and 30 mg/kg groups.Conclusion: Our findings suggest that administration of DEX induced dual effects on ANXIETY and DEPRESSION; anxiogenic and depressant effects were observed at lower doses, while anxiolytic or antidepressant effects were detected at higher doses.
