Panchagavya Ghrita (PG), according to Ayurvedic formulary of India (AFI), is used to treat epilepsy (apasmara), fever (jvara), mania (unmade) and jaundice (kamala). In the present study, we examined its effect on convulsions, oxidative stress and cognitive impairment in pentylenetetrazole (PTZ) induced seizures in rats. PG @ 250, 500, 1000, 2000 and 4000 mg/kg was administered orally for 7 days to male Wistar rats. On day 7, PTZ (60 mg/kg) was injected intraperitoneally 2 h after the last dose of PG. Sodium valproate (300 mg/kg) was used as positive control. Latency to myoclonic jerks, clonus and generalized tonic clonic seizures (GTCS) were recorded for seizure severity. Cognitive impairment was assessed using elevated plus maze and passive avoidance tests. Malondialdehyde and reduced glutathione levels were measured in rat brain. The results have shown that pretreatment with PG @ 500, 1000, 2000 and 4000 mg/kg exhibited 16.6, 33.3, 50 and 100% protection against occurrence of GTCS. The pretreatment with PG has significantly improved cognitive functions and the oxidative stress induced by seizures demonstrating its protective effect against PTZ induced seizures, and further, use of PG as an anticonvulsant in Ayurvedic system of medicine.
