Evaluation of antiepileptic activity of trachyspermum ammi (ajwain oil) alone and as an adjuvant to diazepam in swiss albino mice

Background: Epilepsy is defined as a group of chronic neurological disorders characterized by recurrent and unprovoked seizures. Taking into account high prevalence of epilepsy and the adverse effects of the current antiepileptic agents which leads to noncompliance, more attempts should be made to re-explore the natural sources for new drug discoveries.

Methods: The antiepileptic activity of Ajwain oil alone and as adjuvant to diazepam in swiss albino mice was evaluated using Maximum Electro Shock (MES) and Pentylenetetrazole (PTZ) induced seizure model. A total of forty eight (N=48) swiss albino mice weighing 20-30g of either sex were used in the study. Animals were divided into 2 sets of 24 animals each, which were further divided into 4 groups of 6 animals each. In either set, control received - 2% Tween 80 (10mg/kg); standard- Diazepam (2mg/kg); Test drug- Ajwain oil (75mg/kg) and Adjuvant group- Ajwain oil (75mg/kg) + Diazepam (2mg/kg). All the drugs were given intraperitoneally 30min before inducing seizures.

Results: One way ANOVA was used to compare the means of all the groups followed by post Hoc Tukey’s test for statistical evaluation. In MES model, test drug showed statistically significant antiepileptic activity compared to control, however the results were comparable to standard. In PTZ, adjuvant therapy showed significant activity compared to standard, with a p value <0.001.

Conclusions: Therefore, authors conclude that Ajwain oil has significant anti-epileptic activity.
