Tinospora cordifolia attenuates antipsychotic drug induced hyperprolactinemia in Wistar rats
Journal Title: Asian Pacific Journal of Reproduction - Year 2019, Vol 8, Issue 3
Abstract
Objective: To evaluate the anti-hyperprolactinemic effect of methanolic extract of Tinospora cordifolia against antipsychotic/neuroleptic drug induced hyperprolactinemia. Methods: A total of 48 Wistar albino rats were chosen in the study. To induce hyperprolactinemia, haloperidol at 5 mg/kg/day was intraperitoneally administered for 16 continuous days and sulpiride at 20 mg/kg/day was administered intraperitoneally for 28 continuous days. Methanolic extract of Tinospora cordifolia at 200 mg/kg/day and 400 mg/kg/day were administered orally 30 min before administration of haloperidol and sulpiride for 16 and 28 days, respectively. Then, we had evaluated prolactin, dopamine and antioxidant status in the treatment group as compared to haloperidol and sulpiride. Results: There was a significant (P<0.05) increase in serum prolactin level and decrease in dopamine level in the haloperidol and sulpiride treated animals. However, methanolic extract of Tinospora cordifolia significantly (P<0.05) decreased serum prolactin level and increased brain dopamine level. Further, superoxide dismutase and catalase level were also decreased significantly in the haloperidol and sulpiride treated groups as compared to those of the control group and the antioxidant status was restored significantly on treatment with methanolic extract of Tinospora cordifolia. Furthermore, methanolic extract of Tinospora cordifolia also reduced total leukocyte count, and increased red blood cell count and hemoglobin concentration. In addition, the spleen did not show signs of infection or inflammation in the experiments. Conclusions: Methanolic extract of Tinospora cordifolia has a significant anti- hyperprolactinemic effect which may be attributed to neuroprotective and antioxidant effects of its signature constituents like stepharanine.
