Resistance to antiepileptic drugs (AEDs) is a major problem in epilepsy treatment. However, mechanisms of resistance are only incompletely understood. We have recently shown that repeated administration of the AED phenytoin allows selecting resistant and responsive rats from the amygdala kindling model of epilepsy, providing a tool to study mechanisms of AED resistance. We now tested whether in...

Argyreia speciosa (Convolvulaceae) is regarded as a ‘Rasayan’ drug in the Ayurveda system of medicine to cure diseases of the nervous system. This work researched the action of the hydroalcoholic extract of A. speciosa root (ASE) on experimentally-induced anxiety, depression and convulsion in rodents. ASE (100, 200, 500 mg/kg, p.o.) was tested for the elevated plus maze, open field, forced swim...

BACKGROUND AND OBJECTIVE: Epilepsy is one of the most common neurologic disorders that presents in a large number of drug-resistant patients. Given the presence of the anticonvulsant compounds in Cannabis and its use in traditional medicine, this study aims to evaluate the effect of Cannabis sativa extract on the treatment of seizures METHODS: In this experimental study, 40 Syrian male rats wer...

Background & Aims: Epilepsy is a central nervous system disorder that appears as sudden convulsions, and transient, repetitive and unpredictable movment, with sensory-motor and autonomic sources. Nowadays, patients with epilepsy use various types of chemical drugs which turn out side effects and cause drug resistance in long-term use. Ease of using herbal plants and their public acceptance have...

Background Surgeries causing nerve injury can result in chronic neuropathic pain, which is clinically managed by using antidepressant or anticonvulsant drugs. Currently, there is a growing interest for investigating preemptive treatments that would prevent this long-term development of neuropathic pain. Our aim was to compare analgesic drugs using two distinct treatment modalities: either treat...

BACKGROUND Losartan and telmisartan, angiotensin AT1 receptor antagonists, are widely used antihypertensive drugs in patients. It is also known that arterial hypertension is often present in people with epilepsy, therefore, drug interactions between AT1 receptor antagonists and antiepileptic drugs can occur in clinical practice. OBJECTIVES The aim of the current study was to assess the effect...

A series of 5,7-dibromoisatin semicarbazones have been synthesized in good yield, involving aryl urea and aryl semicarbazide formation. The structures of the synthesized compounds were confirmed on the basis of their spectral data. All the compounds were evaluated for anticonvulsant and CNS depressant activities. Anticonvulsant activity was determined after intraperitoneal (i.p.) administration...

Release of prostaglandins in brain after spontaneous and experimentally induced seizures, has been demonstrated. The possible role of prostaglandins in modulation of seizure activity is still inconclusive. In the present study, the effects of aspirin and its interaction with the anticonvulsants (diazepam and sodium valproate) were studied in pentylenetetrazole (PTZ) and maximal electroshock (ME...

Cannabinoids have been shown to have anticonvulsant properties, but no studies have evaluated the effects of cannabinoids in the hippocampal neuronal culture models of acquired epilepsy (AE) and status epilepticus (SE). This study investigated the anticonvulsant properties of the cannabinoid receptor agonist R(+)-[2,3-dihydro-5-methyl-3-[(morpholinyl)methyl]pyrrolol[1,2,3 de]-1,4-benzoxazinyl]-...

The central nervous system (CNS) depressant and anticonvulsant activities of Citrus limon (L.) Osbeck, Rutaceae, essential oil (EO) were investigated in animal models. The EO (50, 100 and 150 mg/kg) injected by oral route (p.o.) in mice caused a significant decrease in the motor activity of animals when compared with the control group, up to thirty days after the administration and the dose of ...
