Opioid Receptor

Opioid Receptor

Opioid receptors are a group of G protein-coupled receptors that mediate the effects of endogenous and exogenous opioids. These receptors play a central role in pain modulation, mood regulation, and addictive behaviors. Opioid receptor agonists and antagonists are extensively used in pain management and addiction treatment, as well as in research on neurological and psychiatric disorders. At CymitQuimica, we provide a comprehensive selection of high-quality opioid receptor modulators to support your research in neurobiology, pain management, and addiction therapy.
