Levetiracetam | antiepileptic drug | seizures


Levetiracetam and acute renal failure (ARF) was highlighted as a potential signal in the paediatric signal detection sprint. The paediatric population and ARF was the starting point for this assessment but the signal expanded to cover reports of all ages as well as encompassing interstitial nephritis. There are more than 150 reports on levetiracetam with ARF and/or interstitial nephritis in the WHO Global database of Individual Case Safety Reports, VigiBase®, although many of these reports turned out to be duplicates (WHO,20212)



Levetiracetam is one of the newer generation antiepileptic drugs (AEDs). It is considered to be safer than many of the older AEDs. It is an effective anticonvulsant and its main adverse drug reactions are tiredness and behavioural changes. The active substance of levetiracetam is a pyrrolidone derivate. The mechanism of action is not fully elucidated but in vitro studies suggest that an interaction between levetiracetam and the synaptic vesicle protein 2A results in antiseizure activity. Levetiracetam is excreted primarily via urine by glomerular filtration followed by tubular reabsorption. Elimination of levetiracetam is correlated to creatinine clearance.




Indications and usage
Levetiracetam is indicated as adjunctive therapy in the treatment of partial onset seizures in adults and children 4 years of age and older with epilepsy.
