Age-related morphine kinetics

Abstract

The kinetic disposition of morphine was compared in 13 young and 7 older healthy subjects after a single intravenous dose of 10 mg/70 kg morphine. The apparent volume of distribution at steady state in elderly subjects was only half of that in young subjects. This difference was derived from reductions in both central and peripheral kinetic compartment volumes in the older subjects. The beta elimination phase for morphine was more rapid, but its plasma clearance was reduced in older subjects. Calculation of the peripheral compartment morphine concentration for these subjects indicated that drug concentration in this kinetic space was higher in older subjects for 1.5 hr after dosing.

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.
