Lamotrigine is a first drug since lithium approved for maintenance treatment of bipolar type I. Lamotrigine-induced extrapyramidal side effects are rarely reported in literatures. In this letter, we have presented a case of Bipolar disorder which has induced dystonia to lamotrigine. Lamotrigine is a phenyltriazine derivative [1] which was originally approved by USA Food & Drug Administration fo...

BACKGROUND Lamotrigine is an anticonvulsant drug indicated for the maintenance treatment of bipolar I disorder and for various types of epilepsy. An orally disintegrating tablet (ODT) of lamotrigine was developed to provide a formulation option that might increase patient convenience and satisfaction. METHODS Subjects with mood disorders who reported difficulty swallowing currently prescribed...

Lamotrigine is an effective antiepileptic drug with few adverse effects. Nystagmus is one of the commonly observable signs of lamotrigine overdose, which may result from central nervous system involvement. However, the physiologic basis of lamotrigine-induced nystagmus is not fully understood. Here we report a patient who presented with lamotrigine-associated nystagmus that was probably related...

There is considerable evidence suggesting, that older antiepileptic drugs (AEDs) and some of the newer ones decrease bone mineral density (BMD). However, there is only limited and conflicting data concerning the effect of levetiracetam on BMD. In this cross-sectional study we analysed data from 168 adult consecutive outpatients treated with AEDs for more than 2 years, and who underwent measurem...

Antiepileptic drugs (AEDs) are prescribed commonly to women of childbearing age. In utero exposure to some AEDs can have significant cognitive and behavioral consequences for the unborn child. Recently, prospective studies of women taking AEDs during pregnancy have added significantly to our understanding of cognitive and behavioral teratogenic risks posed by fetal AED exposure. Valproate is cl...

The anticonvulsant lamotrigine is associated with idiosyncratic drug reactions, especially skin rashes. Most idiosyncratic reactions are believed to be caused by reactive metabolites. Previous studies have found evidence that an arene oxide is formed in rats; however, when we incubated radiolabeled lamotrigine with rat liver microsomes virtually no covalent binding was detected, and the expecte...

UNLABELLED Epilepsy is very prevalent among elderly inpatients and treatment is far from ideal. OBJECTIVE To analyze prescribing patterns of antiepileptic drugs (AEDs) for hospitalized elderly with epilepsy, their relations with comorbidities and comedications. METHOD We assessed prescription regimen of elderly patients that were under AED use for treatment of epileptic seizures, during hos...

New anti-epileptic drugs differ from existing standard therapies not in their clinical efficacy, but in their side-effects profiles. To determine the relative economic value of these agents, one must compare drug costs, costs of resources employed in the management of adverse events, and costs associated with therapeutic switching. In this economic analysis, carbamazepine (CBZ) and lamotrigine ...
