The effects of four commonly used antiepileptic drugs (phenobarbital, diphenylhydantoin, clonazepam and dipropylacetate) on the uptake of amino acids were investigated in mouse cerebral slices. Phenobarbital and diphenylhydantoin showed a net influence on the transport of the neutral amino acids that are also precursors of monoamine neurotransmitters, increasing their uptake. A similar effect was observed for diphenylhydantoin on GABA uptake. The increase in phenylalanine and valine uptake induced by phenobarbital was at least partly due to a decreased release of these metabolites. No major effects were observed for clonazepam and dipropylacetate. Our findings seem to indicate that some antiepileptic drugs may influence cerebral transport of neurotransmitter substances; further investigations are needed to find out whether these effects play a role in the antiepileptic action of these drugs.
