Review on the Relevance of Therapeutic Drug Monitoring of Levetiracetam

In clinical practice, most dosing schemes for pharmacological treatment of epilepsy are based on efficacy (i.e. seizure reduction) and tolerability (i.e. side-effects). However, one can anticipate clinical effects (efficacy and tolerability) by measuring anti-epileptic drug (AED) serum drug concentrations (SDCs). This constellation is true for some older AEDs, such as phenytoin, since they imply regular monitoring of SDCs due to their non-linear pharmacokinetics and/or small therapeutic range [1].
