Abstract Monitoring plasma levels of antiepileptic drugs for the treatment and prophylaxis of
epilepsy is one of the strategies enabling clinical results to improve by reducing adverse affects
and increasing effectiveness.
The objectiveof this article is to review the basic aspects in the monitoring of antiepileptic
drugs using a consensus document prepared and endorsed by the pharmacokinetics and pharmacogenetics working group (PK.gen) of the Sociedad Espa˜ola de Farmacia Hospitalaria (Spanish

Introduction
The main objective of pharmacokinetic monitoring of
antiepileptic drugs is to optimise treatment by studying drug
levels in biologicalmatrices. Adapting individual doses is no
easy task, due to the presence of factors including: a) the
considerable inter-individual pharmacokinetic variability of
antiepileptic drugs; b) the use of these drugs as prophylactics for long-term epileptic seizure control, and c) having no
defined correlation between efficacy and a biological marker
that could help with decision-making.1
It isobvious that epilepsy treatment has benefited
from the determination of serum concentrations during
treatments. High inter- and intra-individual variability,
serum concentration-effect relationships, drug interactions, and so on, are all aspects that make personalising
antiepileptic treatments through pharmacokinetic determination recommendable.2
However, the fact that these techniques have...
