Abstract:
The effect of various antiepileptics on the retinol storage in rat liver was tested. We observed a dose- and time-dependent reduction in the hepatic storage of retinol after the administration of several of these drugs. Administration for 11 weeks of phenobarbital, primidone and carbamazepine in doses comparable to those used in humans reduced the retinol concentration in the Liver by 17-33% compared to control rats. The plasma retinol levels remained unaffected in all the rats. Plasma retinol from 31 epileptic children had plasma levels between 0.7 and 2.4 nmol/ml, which is regarded as normal.
