Effect of traditional medicine brahmi vati and bacoside A-rich fraction of Bacopa monnieri on acute pentylenetetrzole-induced seizures, amphetamine-induced model of schizophrenia, and scopolamine-induced memory loss in laboratory animals.

OBJECTIVE: Brahmi vati (BV) is an Ayurvedic polyherbal formulation used since ancient times and has been prescribed in seizures associated with schizophrenia and related memory loss by Ayurvedic practitioners in India. The aim of the study was to investigate these claims by evaluation of anticonvulsant, antischizophreniac, and memory-enhancing activities. Antioxidant condition of brain was determined by malondialdehyde (MDA) and reduced glutathione (GSH) levels estimations. Acetylcholinesterase (AChE) was quantitatively estimated in the brain tissue. METHODS: Brahmi vati was prepared in-house by strictly following the traditional Ayurvedic formula. Bacoside A rich fraction (BA) of Bacopa monnieri was prepared by extraction and fractionation. It was than standardized by High Performance Liquid Chromatography (HPLC) and given in the dose of 32.5mg/kg body weight to the different groups of animals for 7days. On the seventh day, activities were performed adopting standard procedures. KEY FINDINGS: Brahmi vati showed significant anticonvulsant, memory-enhancing and antischizophrenia activities, when compared with the control groups and BA. It cause significantly higher brain glutathione levels. Acetylcholinesterase activity was found to be significantly low in BV-treated group. CONCLUSION: The finding of the present study suggests that BV may be used to treat seizures associated with schizophrenia and related memory loss.
