[Clinicopharmacologic study of blood carbamazepine levels in a group of epileptic patients].

Clinico-pharmacological evaluation on Carbamazepine serum levels was performed in a group of epileptic patients. CBZ (Carbamazepine) blood levels have been detected in a heterogeneous group of epileptic patients taking several other antiepileptic drugs. Patients in which there was a good reduction of epileptic seizures after CBZ was added, had a mean blood level of 4.2 plus or minus 1.4 microgram/ml. When Dyphenilhydantoine (DPH) and/or Phenobarbital (PB) were associated with CBZ they both decreased CBZ blood levels; on the contrary CBZ did not appear to modify DPH and PB blood levels.
