Article Synopsis
  • Stimulation of muscarinic M/M receptors can reduce the reinforcing effects of cocaine and may help with cravings and relapse in addiction.
  • A study tested whether activating these receptors could speed up the extinction process in mice trained to self-administer cocaine, finding that certain agonists significantly reduced the number of sessions needed for extinction.
  • Results indicated that treating mice with receptor stimulation not only hastened extinction but also minimized relapse risk to cocaine, suggesting a lasting neurochemical change beyond just the learning process.

Background: Cocaine addiction is a chronic brain disease affecting neurotransmission. Muscarinic cholinergic receptors modulate dopaminergic signaling in the reward system, and muscarinic receptor stimulation can block direct reinforcing effects of cocaine. Here, we tested the hypothesis that specific muscarinic M receptor stimulation can attenuate the discriminative stimulus effects and conditioned rewarding effects of cocaine, measures believed to predict the ability of cocaine and cocaine-associated cues to elicit relapse to drug taking.

Effects of muscarinic receptor antagonists on cocaine discrimination in wild-type mice and in muscarinic receptor M, M, and M receptor knockout mice.

Muscarinic M/M receptor stimulation can reduce abuse-related effects of cocaine and may represent avenues for treating cocaine addiction. Muscarinic antagonists can mimic and enhance effects of cocaine, including discriminative stimulus (S) effects, but the receptor subtypes mediating those effects are not known. A better understanding of the complex cocaine/muscarinic interactions is needed to evaluate and develop potential muscarinic-based medications.

This study examined the impact of disaster-related stressors and peri-trauma emotional reactions on mental health 10 months after the 2004 Southeast Asian tsunami disaster in a sample of 660 Danish tourists evacuated from the disaster area. The estimated rates of posttraumatic stress disorder and depression were 10.2% and 6.
