Abstract

Opioids cause constipation by binding to specific opioid receptors in the enteric and central nervous systems. First-pass glucuronidation limits systemic bioavailability of oral naloxone. This study was designed to determine if oral naloxone could reverse opioid-induced constipation without precipitating abstinence or recrudescence of pain in opioid-dependent individuals. Concentrations of unmetabolized and total naloxone, including naloxone glucuronide, were measured by radioimmunoassay. A dose-related increase in symptoms of laxation resulted in all three opioid-dependent patients studied that paralleled the increase in active and total naloxone plasma levels. Withdrawal symptoms occurred with plasma naloxone area under the plasma concentration-time curves above 550 ng.min/ml and with dosing intervals less than 3 hours. Peak plasma levels did not predict withdrawal. Oral naloxone ameliorates opioid-induced constipation in opioid-dependent persons. Titration of dose to a maximum of 12 mg at least 6 hours apart may be needed to avoid adverse reactions.

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.
