New medicines to increase opioid pain relief while lowering addiction risk

Pharmacological targeting of nascent modulators of opioid signaling

NIH-funded research University of Florida · NIH-11180377

Researchers are developing drugs that aim to make opioid pain relief stronger while reducing the chance of dependence for people who need pain control or who struggle with opioid misuse.

What this research studies

This project will look for new medicines that change how opioid receptors work by using large genetic screens and mouse models, then test many small molecules to find ones that boost pain relief but reduce addictive effects. The team already found receptor-like components that act as "anti-opioid" modulators and showed in knockout mice that removing them increased analgesia and lowered dependence and tolerance. Most experiments are currently done in lab assays and animals, so people are not being enrolled at this stage. If safe and effective compounds are identified, they could be advanced into human clinical trials in the future.

Who could benefit from this research

Good fit: Future trials would likely include people who need opioid pain control for acute or chronic pain and possibly people at risk for or living with opioid use disorder.

Not a fit: Because this is preclinical, people seeking immediate treatment changes or those currently in opioid treatment programs are unlikely to benefit right now.

Why it matters

Potential benefit: Could lead to drugs that provide stronger pain relief with less tolerance, dependence, and overdose risk.

How similar studies have performed: Animal and genetic studies have shown proof-of-principle that altering these components changes opioid effects, but translating this into safe human medicines remains unproven.
