BACKGROUND The aim of the study was to examine effects of an acute and chronic treatment with trazodone, a serotonin antagonist and reuptake inhibitor (SARI), on the protective activity of four classical antiepileptic drugs provided in the maximal electroshock test in mice. METHODS Electroconvulsions were produced in mice by means of an alternating current (50 Hz, 25 mA, 0.2 s) and delivered ...

The cannabinoid CB receptor has been shown to be the primary site of action for cannabinoid-induced effects on the central nervous 1 system. Activation of this receptor has proven to dampen neurotransmission and produce an overall reduction in neuronal excitability. Cannabinoid compounds like D-tetrahydrocannabinol and cannabidiol have been shown to be anticonvulsant in maximal electroshock, a ...

Background: The development of newer classes of antiepileptic drugs has created several opportunities for the treatment of epilepsy. Aims & Objective: The present study was designed to assess the effect of amlodipine on the antiepileptic action of lamotrigine, gabapentin and topiramate in the mouse maximal electroshock-induced seizure model. Materials and Methods: 300 Adult male mice were divid...

The ATP-gated P2X7 receptor (P2X7R) is a non-selective cation channel which senses high extracellular ATP concentrations and has been suggested as a target for the treatment of neuroinflammation and neurodegenerative diseases. The use of P2X7R antagonists may therefore be a viable approach for treating CNS pathologies, including epileptic disorders. Recent studies showed anticonvulsant potentia...

Nefopam is a centrally acting non-opioid analgesic with a mechanism of action that is not completely understood. Adverse effects associated with the therapeutic use and overdose of nefopam are mainly associated with the central nervous system, such as hallucinations, cerebral edema and convulsions. The aim of this study was to assess the effect of nefopam on the electrical threshold and its inf...

There is emerging evidence to support the efficacy of some antiepileptic drug (AED) combinations in refractory epilepsy. Definitive clinical studies are, however, difficult to perform. Experimental seizure models can be employed to identify potentially useful combinations for subsequent clinical evaluation. We have investigated the anticonvulsant effects of topiramate (TPM) in combination with ...

The objective of the present study was to evaluate the anxiolytic, antidepressant, and anticonvulsant activity of the methanolic extract of Swertia corymbosa (SCMeOH). After acute toxicity test, oral treatment with SCMeOH at doses of 125, 250, and 500 mg/kg behavioral models of open field, elevated-plus-maze, actophotometer, rotarod, pentylenetetrazole, isoniazid, and maximal electroshock induc...

BACKGROUND Cardiac dysfunction is one of the possible causes of sudden unexpected death in epilepsy (SUDEP). Therefore, it was the objective of this study to evaluate the cardiac and electrocardiographic parameters after seizures induced by maximal electroshock (MES) in Wistar rats. METHODS Electroshock seizures were induced in Wistar rats through a pair of ear-clip electrodes (10 mA at a fre...

OBJECTIVE Homer1a is a protein that regulates metabotropic glutamate receptors involved in neural plasticity processes. Recently, we demonstrated that Homer1a mRNA is enhanced after pilocarpine-induced status epilepticus. Here, we investigated whether a single acute seizure triggered by means of pentylenetetrazole (PTZ) injection or maximal electroshock (MES) stimulation (2 different seizure mo...
