Description

Curator's Comment: description was created based on several sources, including: http://en.pharmacodia.com/web/drug/1_12280.html | https://www.ncbi.nlm.nih.gov/pubmed/16433932 | https://www.ncbi.nlm.nih.gov/pubmed/6301606 | doi:10.3181/00379727-77-18904

Nalorphine has a mixed opioid agonist-antagonist properties. Nalorphine inhibits the cholinesterases of mouse brain, bovine erythrocytes and horse serum. It acts on mu-, k- and sigma-opioid receptors. Nalorfin by virtue of the agonistic effect has an analgesic effect but to a much lesser extent than morphine. Initially, before the appearance of a "pure" morphine-naloxone antagonist, nalorphine was used as an antidote for severe respiratory depression and other body function disorders caused by acute poisoning in case of an overdose of morphine, promedol, fentanyl or other narcotic analgesics, or with increased sensitivity to them. At present, nalorphine is practically not used for this purpose. It was replaced by naloxone. Large doses of nalorphine can cause nausea, cramps, drowsiness, headache, mental stimulation.

Sample Use Guides

In Vivo Use Guide

Adults appoint 0,005 - 0,01 g (1 - 2 ml of a 0.5% solution). If the effect is insufficient, the injections are repeated at intervals of 10 to 15 minutes. The total dose should not exceed 0.04 g (8 ml of 0.5% solution).

Route of Administration: Other

In Vitro Use Guide

Maximum stimulation of [35S]GTPyS binding by Nalorphine using a single saturating concentration of ligand (10 uM) was compared with stimulation by DAAMGO (10 uM). Intrinsic activity determined for Nalorphine in C6 glioma cells was 9%.
