Nanoparticle drug delivery provides pain relief and more effective opioid alternative in animal study

An international team of researchers has used nanoparticles to deliver a drug into specific compartments of nerve cells, dramatically increasing its ability to treat pain in mice and rats. The drug that the researchers encapsulated into nanoparticles is an FDA-approved drug used to prevent nausea and vomiting that had previously failed clinical trials as a pain medication.
