Aprepitant's roles in abating seizures, behavioral, and cognitive deficits in mice model of epilepsy.

BACKGROUND

Aprepitant (APR), a neurokinin 1 receptor antagonist, is an approved drug for treating chemotherapy-induced nausea and vomiting.

OBJECTIVES

Investigate the beneficial roles of APR alone or in combination with sodium valproate (VPA) against lithium pilocarpine [li-pilo]-induced seizures, behavioral changes, and cognitive deficits.

METHODS

Thirty male mice were divided into five groups, each containing 6. "Vehicle Group I," "Control Group II "li-pilo, " Valproate (VPA) group III (400 mg/kg/i.p.), "APR group IV, " and "Combination Group V." Videos of mice were recorded, and they were watched for episodes of spontaneous recurring seizures (SRS). Behavioral Tests were performed. At the end of the study, animal brains were taken for biochemical assays and gene expression studies.

RESULTS

APR partially protected against SRS with partial restoration of average behavioral and standard cognitive skills associated with a significant increase in brain SOD activity and a significant decrease in MDA, IL-1β, NF-КB, and SP-3 levels in relation to the control group. Interestingly, a combination of APR with VPA in epileptic mice showed complete protection against li-pilo-induced behavioral changes and cognitive deficits, a significant increase in brain SOD activity, and a considerable decrease in MDA, IL-1β, NF-ΚB, and SP levels to normal.

CONCLUSION

Using APR as an adjuvant to VPA is more effective in protecting against li-pilo-induced seizures, behavioral changes, and cognitive deficits due to its antioxidant, anti-inflammatory, and NK1 antagonist effects than using APR alone as drug therapy.
