Los fármacos antiepilépticos constituyen el tratamiento inicial en pacientes con epilepsia. Los antIepilépticos producidos después del año 2000 se conocen como fármacos de tercera generación. Estas drogas ofrecen nuevos mecanismos de acción y una farmacocinética más favorable, minimizando efect...

El ácido valproico como agente sensibilizador al tratamiento anticáncer

Gac. méd. Méx; 155 (4), 2019
Resumen El ácido valproico es un fármaco antiepiléptico con más de 50 años de uso clínico. En la década pasada se descubrieron sus efectos anticancerígenos. El análisis de grupos de pacientes que utilizaron este fármaco durante años ha mostrado que disminuye la frecuencia de cáncer de cabeza ...

The anticonvulsant effects of Ducrosia anethifolia (Boiss) essential oil are produced by its main component alpha-pinene in rats

Arq. neuropsiquiatr; 77 (2), 2019
ABSTRACT Ducrosia anethifolia has been recommended as a remedy for neurological disorders. However, the anticonvulsant effects of D. anethifolia essential oil (DAEO) and its major constituent α-pinene have not yet been clarified. Methods: A rat model of pentylenetetrazole (PTZ)-induced convulsions ...

The alterations of microvasculature, tyrosine phosphorylation, and lipid peroxidation in kidney of rats treated with valproic acid

Int. j. morphol; 37 (1), 2019
SUMMARY: Valproic acid (VPA), an antiepileptic drug, has been demonstrated to damage histology and to change tyrosine phosphorylation patterns with increased oxidative stress in perirenal tissues. This study aimed to investigate the effect of VPA on microstructure, tyrosine phosphorylation, and lipid per...

Effect of gabapentin pretreatment on myoclonus after etomidate: a randomized, double-blind, placebo-controlled study

Rev. bras. anestesiol; 66 (4), 2016
Abstract Aim: To evaluate the effects of three different doses of gabapentin pretreatment on the incidence and severity of myoclonic movements linked to etomidate injection. Method: One hundered patients, between 18 and 60 years of age and risk category American Society of Anesthesiologists I-II, with ...

Effect of carbamazepine and gabapentin on excitability in the trigeminal subnucleus caudalis of neonatal rats using a voltage-sensitive dye imaging technique

Biol. Res; 48 (), 2015
BACKGROUND: The antiepileptic drugs carbamazepine and gabapentin are effective in treating neuropathic pain and trigeminal neuralgia. In the present study, to analyze the effects of carbamazepine and gabapentin on neuronal excitation in the spinal trigeminal subnucleus caudalis (Sp5c) in the medulla oblo...

The impact of different antiepileptic drugs on the sedation of children during magnetic resonance imaging

Rev. bras. anestesiol; 64 (5), 2014
Background and objectives: The induction and inhibition of cytochrome P450 isoenzymes by antiepileptic drugs lead to changes in the clearance of anesthetic drugs eliminated via hepatic metabolism. We investigated the duration of the sedation and additional anesthetic needs during magnetic resonance imagi...

Activation of group II metabotropic glutamate receptors blocks zinc release from hippocampal mossy fibers

Biol. Res; 47 (), 2014
BACKGROUND: The hippocampal CA3 area contains large amounts of vesicular zinc in the mossy fiber terminals which is released during synaptic activity, depending on presynaptic calcium. Another characteristic of these synapses is the presynaptic localization of high concentrations of group II metabotropic...

Desenvolvimento pré-embrionário em ratas tratadas com oxcarbazepina nos quatro primeiros dias após a inseminaçäo
Pre-embryo development in rats treated with oxcarbazepine in the first four days after insemination

A oxcarbazepina é uma droga antiepiléptica de alta eficácia e poucos efeitos colaterais, mas pouco estudada quanto a seus efeitos durante a gestaçäo humana e animal. OBJETIVO: Verificar se a administraçäo de oxcarbazepine em ratas, nos quatro primeiros dias após a inseminaçäo, altera a viabilid...

Estudo comparativo entre oxcarbazepina e carbamazepina contra crises convulsivas tônico-clônicas induzidas por eletrochoque em ratos
Effects of Oxcarbazepine and Carbamazepine as anticonvulsivants induced by electric shock in rats

O trabalho visa comparar a eficácia anticonvulsivante da oxcarbazepina e da carbamazepina e a relaçao dose-efeito das mesmas. Foram utilizados 64 ratos albinos Wistar divididos em sete grupos, que receberam doses de OCBZ e CBZ em diferentes concentraçöes, sendo submetidos 30 minutos depois a eletroch...
