Mephenytoin hydroxylation deficiency in Caucasians: Frequency of a new oxidative drug metabolism polymorphism

Wedlund, P J, Aslanian, W S, McAllister, C B, Wilkinson, G R, Branch, R A·1984·Clinical Pharmacology and Therapeutics

Abstract

The ability of normal subjects to hydroxylate mephenytoin (100 mg) or debrisoquine (10 mg) after oral dosing was investigated in 156 unrelated Caucasians living in middle Tennessee. Urinary recovery of 4-hydroxymephenytoin (4-OH-M) and the urinary S:R enantiomeric ratio of mephenytoin measured in an 8-hr urine sample were investigated as phenotypic traits for mephenytoin, and the urinary metabolic ratio of debrisoquine was used to determine the debrisoquine hydroxylase phenotype. Both urinary 4-OH-M and the S:R ratio of mephenytoin discriminated between extensive (EM) and poor (PM) metabolizers of mephenytoin. The frequencies of PMs for mephenytoin and debrisoquine hydroxylation activity were 2.6% and 7.0%. These two defects in oxidative metabolism were not observed in the same subjects, which suggests that 4-hydroxylation of mephenytoin is a new polymorphism independent of that for debrisoquine.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
