Small effects of valproic acid on the plasma concentrations of clozapine and its major metabolites in patients with schizophrenic or affective disorders.

abstract：BACKGROUND:The anticonvulsant properties of phenytoin (PHT) were discovered in 1938. Since then, it has been one of the most widely used antiepileptic drugs. It is slowly absorbed, extensively plasma protein-bound, exhibits a nonlinear, concentration-dependent pharmacokinetic profile, and has a narrow therapeutic range...
