The cholinergic system and nociception in the primate: interactions with morphine

Psychopharmacologia
A Pert

Abstract

In Experiment 1 the shock titration task was used to evaluate the antinoceptive properties of 5 different classes of cholinergic compounds in the rhesus monkey. Only scopolamine and high doses of physostigmine were effective in elevating the shock threshold. The apparent antinociceptive effect of physostigmine, however, was difficult to separate from its nonspecific behavioral depressant effect and was probably not related to an increase in cholinergic tone. Experiment 2 examined the interaction of morphine with arecoline, scopolamine and physostigmine. Only scopolamine (0.05 and 0.1 mg/kg) and high doses of physostigmine (0.1 mg/kg) interacted with morphine in the shock titration paradigm. The multiplicative interaction of morphine with scopolamine was confirmed in Experiment 3 over a wider range of doses. It was concluded that morphine and the cholinergic compounds produce antinociceptive effects through different mechanisms of the pain system.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
