− Epilepsy is a brain disorder that affects millions of people worldwide. It is characterized by recurrent and unpredictable seizures that are usually controlled with antiepileptic/anticonvulsive drugs. However, most antiepileptic drugs produce various side effects such as tolerance and sedation. Thus, there is a growing interest for alternative anticonvulsive drugs, preferably from natural or ...

We have shown that morphine has an anticonvulsive effect against maximal electroconvulsive shock (MES) in mice, and this effect is antagonized by histamine H1-receptor antagonists. Brain histamine is localized both in neurons and in mast cells, and morphine is known to enhance the turnover of neuronal histamine and to release histamine from mast cells. In the present experiments, compound 48/80...

The present study was performed to investigate whether or not carvedilol (a beta-adrenoreceptor antagonist) potentiates the anticonvulsive activity of gabapentin against ICES (Increasing current electroshock) and PTZ (Pentylenetetrazole) induced seizures in mice. Further the effect of combination of both the drugs on spatial working memory and locomotor activity on rotarod was also evaluated. T...

In respect to the functional activities of D-cycloserine scientists suggested anticonvulsive activities [4,5] and furthermore the application seems to improve memory and cognitive function. Recently we discovered that D-Cycloserine has the ability to block kynurenic acid synthesis [6]. Kynurenic acid, a metabolite along the kynurenine pathway of tryptophan degradation blocks the glycine sites o...

Valerenic acid (VA)-a β2/3-selective GABA type A (GABAA) receptor modulator-displays anxiolytic and anticonvulsive effects in mice devoid of sedation, making VA an interesting drug candidate. Here we analyzed β-subunit-dependent enhancement of GABA-induced chloride currents (IGABA) by a library of VA derivatives and studied their effects on pentylenetetrazole (PTZ)-induced seizure threshold and...

hypothyroidism is one of the problems that can cause severe growth and developmental defects in children and infants. by using anticonvulsive drugs (phenobarbital, carbamazepine, navalproate , and phenytoin), liver microsomal enzymes will be increased and will lead to hypothyroidism in infants because of increasing metabolism of t3, and t4 by liver. the purpose of this study was to evaluate the...
