A team of researchers led by Andrew Coop, PhD, professor and chair of the Department of Pharmaceutical Sciences (PSC) at the University of Maryland School of Pharmacy (UMSOP), has developed a new opioid drug that shows great potential to advance treatment and improve quality of life for individuals living with chronic pain. Spotlighted in a recent issue of ACS Chemical Neuroscience, the compound, known as UMB 425, is as strong as morphine, but displays diminished tolerance over time with no obvious toxic effects.
“UMB 425 is a breakthrough in the development of therapeutics to treat chronic pain,” says Coop (on the left in the photo). “Unlike other drugs developed to act on only one biological target, UMB 425 acts on two different opioid receptors in the body. When activated at the same time, these receptors work together to provide pain relief and slow the body’s development of tolerance to the drug. This diminished tolerance allows a lower dose of the opioid to be administered for a longer time period, while still achieving the same level of pain relief.”
