Objective : To evaluate the possible role of the antioxidant activity of the polyherbal formulation, NR-ANX-C and its individual components in reversing haloperidol-induced catalepsy in Swiss albino mice.
Materials and Methods : Catalepsy was induced with haloperidol (1 mg/kg i.p) in 13 groups of male albino mice (n = 6 / group). Three groups received NR-ANX-C (10, 25, 50 mg/kg), three groups received Withania somnifera (1.7, 4.25, 8.5 mg/kg), another three groups Ocimum sanctum (1.7, 4.25, 8.5 mg/kg), three other groups Camellia sinensis (3.4, 8.5, 17 mg/kg) and one group received the vehicle (1% Gum acacia) orally, 30 minutes prior to haloperidol administration, for a duration of seven days. Animals were sacrificed on the seventh day and superoxide dismutase (SOD) activity was estimated in the brain.
Results : A significant (P < 0.01) reduction in the cataleptic scores was observed in all the drug-treated groups as compared to the control, with maximum reduction in the NR-ANX-C 25 mg/kg group. Similarly, a reduction in SOD activity was observed in the NR-ANX-C-, O. sanctum- and the W. somnifera-treated groups. An increase in SOD activity was observed in the C. sinensis-treated groups.
Conclusion : With the exception of C. sinensis, the antioxidant potential of NR-ANX-C and its individual constituents has contributed to the reduction in the oxidative stress and the catalepsy induced by haloperidol administration.
