CARBAMAZEPINE EFFECTS ΟΝ HEPATIC FUNCTION
Abstract
Hepatic disorders consist the third adverse effect, following the ones on skin and blood, because of the CBZ metabolism which mainly occurs in liver. We have studied the clinical liver toxicity of 64 patients administered chronically CBZ as monopharmacy or in combination with other antiepileptic drugs. 23 of our patients were administered carbamazepine (CBZ), 19 carbamazepine and phenobarbital (CBZ-PB), 11 carbamazepine and hydantoin (CBZ-PH) and 11 a combination of all three, carbamazepine, phenobarbital and hydantoin (CBZ-PB-PH). We have measured alkaline phosphatase (ΑΡ), lactate dehydrogenase (LDH), transaminases (SGOT, SGPT), total proteins (ΤΡ), albumins (ALB) and globulins (GLB). As a result, we have fοuηd pathological rates of ΑΡ in 8 patients (35%), of LDH in 2 (9%), SGOT in 2 (9%) and GLB in 2 (9%) following CBZ administration as monotherapy. No relationship between the level of the CBZ derivative, namely 10,11-CBZE, and hepatic functίοn was found. Ιn additio n, never has there been a need for replacing or discontinuing tl1e CBZ administration on any of our patients, because the hepatic function strain was such, that the treatment was unaffected.References
