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 ...

Antiaris toxicaria (Moraceae) was evaluated for anticonvulsant activity in rodents. Animal models used include maximal electroshock test (MEST); pentylenetetrazole-induced (PTZ) convulsions; picrotoxin-induced (PCT) convulsions; strychnine- (STR-) and 4-aminopyridine-induced convulsions. Increase in latency to seizures as well as reduction in duration and frequency of seizures indicated anticon...

H2 histamine receptors are localized postsynaptically in the CNS. The aim of this study was to evaluate the effects of acute (1 day) and prolonged (7 day) administration of the H2 histamine receptor antagonist, famotidine, on the anticonvulsant activity of conventional antiepileptic drugs (AEDs; valproate, carbamazepine, diphenylhydantoin and phenobarbital) against maximal electroshock (MES)-in...

background: cicer arietinum (chickpea) is one of the most important harvests in the world with high nutritional value. lack of essential oils in the seeds of chickpea is an advantage in search for drug-like molecules with less toxicity. we evaluated anticonvulsant effect of c. arietinum in common animal models of epilepsy. methods: dichloromethane extract was obtained from c. arietinum seeds by...

1. The aim of this study was to investigate the possible anticonvulsant effect of a dihydropyridine calcium antagonist, isradipine, which easily crosses the blood-brain barrier displaying high affinity and specificity for the brain L-type voltage-sensitive calcium channel, on maximal electroshock seizures in mice. 2. Isradipine at i.p. doses of 2.5 mg/kg and 5.0 mg/kg was found to cause a stati...

GABA exhibits depolarizing action in the immature neurons due to high intracellular activity of chloride ions. It is maintained by cation-chloride cotransporter NKCC1 which is present in immature brain. Bumetanide is a specific inhibitor of this cotransporter. We studied possible anticonvulsant activity of bumetanide in pentylenetetrazol-induced seizures in three age groups of rat pups (7, 12, ...

An EEG study was carried out in 4 epileptic patients. In each case, Ro 15-1788 caused the disappearance or marked reduction of the epileptic potentials. In 1 case the patient had been pretreated with diazepam; in the other cases there had been no prior benzodiazepine treatment. In the first case, it is possible that Ro 15-1788 acted by abolishing a paradoxical effect of diazepam; in the other c...
