Patients on carbamazepine had a mean 50% lower C/D than the monotherapy group (p < 0.001), indicating that carbamazepine is an inducer of the metabolism of clozapine. Three of them exhibited a much higher C/D ratio when on fluvoxamine compared with the monotherapy group. transporter, is likely to be
We conclude that carbamazepine causes decreased clozapine plasma levels, while fluvoxamine increases the levels. While

The distribution of the ratio concentration/dose (C/D) of clozapine was compared in four matched groups--patients simultaneously treated with benzodiazepines, patients on drugs that inhibit the cytochrome P450 enzyme CYP2D6, patients taking carbamazepine, and those not taking any of these drugs. The result of an inducer on carbamazepine

Carbamazepine was discovered in 1953 by Swiss chemist Walter Schindler.Carbamazepine is typically used for the treatment of In the US, the label for carbamazepine contains warnings concerning: Unlike enzyme competitive inhibition, enzyme induction is a gradual process. Its plasma half-life is about 30 hours when it is given as single dose, but it is a strong inducer of hepatic enzymes and the plasma half-life shortens to about 15 hours when it is given repeatedly.Carbamazepine was discovered by chemist Walter Schindler at J.R.
