Influence of sex and oral contraceptive steroids on paracetamol metabolism.
Open accessAbstract
Paracetamol metabolism was investigated in eight healthy males, eight healthy females and eight healthy females receiving oral contraceptive steroids (OCS). Paracetamol clearance was 22% greater in males compared to the control female group. This difference was entirely due to increased activity of the glucuronidation pathway in males, there being no sex‐related differences in the sulphation or oxidative metabolism of paracetamol. Paracetamol clearance in females using OCS was 49% greater than in the control females. Glucuronidation and oxidative metabolism were both induced in OCS users (by 78% and 36% respectively) but sulphation was not altered. Although sex‐related differences in paracetamol metabolism are unlikely to be of clinical importance, induction of paracetamol metabolism by OCS may have clinical and toxicological consequences.

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.
