WebConclusions: This study shows that phenytoin and carbamazepine have approximately twice the CYP3A4-inducing potency of phenobarbital. The results indicate that 2-fold higher doses of CYP3A4-metabolized drugs may generally be required during concurrent treatment with phenytoin or carbamazepine compared with phenobarbital.
