Encainide biotransformation to its active metabolites O-desmethyl encainide and 3-methoxy-O-desmethyl encainide cosegregates with the polymorphic oxidation of debrisoquine. Because quinidine has been reported recently to be a potent inhibitor of the enzyme responsible for this polymorphism (cytochrome P450db1), we tested the hypothesis that quinidine would selectively inhibit encainide metabolism and alter its effects in subjects with the extensive metabolism phenotype for debrisoquine… Expand
The effect of diltiazem on the disposition of encainide and its active metabolites
TLDR
Diltiazem inhibited the first‐pass metabolism of encainide, resulting in increased bioavailability, which appeared to be caused by the inhibition of debrisoquin 4‐hydroxylase and impairment of other unmeasured metabolic pathways forencainide. Expand
Stereoselective genetically-determined interaction between chronic flecainide and quinidine in patients with arrhythmias.
TLDR
The effects of adding low dose quinidine, a potent inhibitor of P450IID6, to chronic flecainide therapy in patients with arrhythmias were evaluated and it was found that in extensive metabolizer patients receiving chronic fle cainide, increased plasma concentrations will develop if P450 IID6 is inhibited.

Genetically determined stereoselective excretion of encainide in humans and electrophysiologic effects of its enantiomers in canine cardiac Purkinje fibers
TLDR
It is concluded that encainide undergoes preferential metabolism by cytochrome P450IID6; however, this genetically determined stereoselective disposition is unlikely to play a major role in mediating the clinical actions ofencainide. Expand
The roles of CYP2D6 and stereoselectivity in the clinical pharmacokinetics of chlorpheniramine.
TLDR
Stereoselective elimination of chlorpheniramine occurs in humans, with the most pharmacologically active (S)-(+)- enantiomer cleared more slowly than the (R)-(-)-enantiomer. Expand
Clinical implications of the competitive inhibition of the debrisoquin-metabolizing isozyme by quinidine.
TLDR
Clinicians should be alert to unusual drug reactions in patients receiving quinidine concurrently with the other medications because no test is commonly available to determine directly the debrisoquin metabolic phenotype. Expand
Impact of P450 genetic polymorphism on the first-pass extraction of cardiovascular and neuroactive drugs.
This review highlights the present knowledge on the CYP2D6 (sparteine/debrisoquine) and the CYP2C19 (mephenytoin) polymorphisms. The relevant mutations at genomic level affecting protein expressionExpand
In vitro characterization of cytochrome P450 catalysed metabolism of the antiemetic tropisetron.
TLDR
Both inhibition experiments and use of stably-expressed enzymes revealed formation of N-De-ICS to be mediated by CYP3A4, and based on in vitro intrinsic clearances CYP2D6-catalysed 5- OH-ICS and 6-OH-ICS is the predominant route of tropisetron elimination. Expand
Effects of encainide and metabolizer phenotype on ventricular conduction during exercise.
TLDR
If rate-dependent intraventricular conduction slowing could be demonstrated in patients receiving encainide during exercise-induced sinus tachycardia is determined, and this effect is related to the genetic phenotype ofencainide metabolism. Expand
Influence of amiodarone on genetically determined drug metabolism in humans
TLDR
It is suggested that amiodarone decreases the activity of CYP2D6 and may impair the elimination of drugs whose clearance depends on this cytochrome in extensive metabo‐lizers of dextromethorphan. Expand
Induction of polymorphic 4'-hydroxylation of S-mephenytoin by rifampicin.
TLDR
It appears that the activity of the enzyme (P-450 MP) mediating the genetically determined 4'-hydroxylation of S-mephenytoin can be significantly modulated by enzyme inducing agents such as rifampicin and possibly environmental agents with a similar ability. Expand
