Lamotrigine is an antiepileptic drug employed in the treatment of partial epilepsies. We studied its possible interaction with channels other than its known therapeutic target, the voltage-gated sodium channel, using the adult muscle nicotinic acetylcholine receptor as a model system. At the single-channel level, lamotrigine caused a dose-dependent (a) diminution in mean open time, (b) increase...

This study reports the use of lamotrigine, largely as add-on therapy, in 34 children, adolescents and adults with brain damage and resistant seizures. Seventy-four percent of the patients showed a greater than 50% improvement in seizure control with 35% becoming seizure free. This improvement in seizure control was associated with an enhanced quality of life in 65% of the patients as assessed b...

The aim of this study was to assess the effect of three calcium channel antagonists (amlodipine, diltiazem and verapamil) on the anticonvulsant action of lamotrigine (a second generation antiepileptic drug) against maximal electroshock-induced seizures in mice. Results indicated that all three calcium channel antagonists when administered alone [amlodipine (up to 20 mg/kg, ip), diltiazem (up to...

Results of recent studies suggest that the glutamate-glutamine neurotransmitter cycle between neurons and astrocytes plays a major role in the generation of the functional imaging signal. In the current study, the authors tested the hypothesis that activation of voltage-dependent Na(+) channels is involved in the blood oxygenation level-dependent (BOLD) functional magnetic resonance imaging (fM...

The solid state properties and dissolution behavior of lamotrigine in its inclusion complex with βCyclodextrin were investigated.Preformulation study of lamotrigine was carried out. Dialysis study of lamotrigine with β-Cyclodextrin in pretreated dialysis bags showed that lamotrigine binds with βCyclodextrin in the ratio of 1:2. Solid dispersions were prepared by kneading and spray dried method....

BACKGROUND Lamotrigine is an effective anticonvulsant drug that has also been demonstrated to be effective in the treatment of bipolar disorder. We report a case of rhabdomyolysis after intentional overdose in a woman aged 48. CASE PRESENTATION A 48-year-old female presented to the emergency department after an acute ingestion of 6 g of lamotrigine. The patient suffered from bipolar disorder,...

PURPOSE To assess the long-term usefulness of 'new anti-epileptic drugs (AEDs)' (lamotrigine, topiramate, levetiracetam, gabapentin and pregabalin) in institutionalized intellectually disabled patients. Information from RCTs is lacking in this population with severe intellectual and behavioural disabilities. METHODS Retrospective study. Data from the medical files and the pharmacy databases o...
