Results of a new study in mice and rats show that a compound which acts on a specific type of cell receptor found only outside the central nervous system decreases the animals' pain responses. But the researchers caution that studies investigating the safety and efficacy of this compound in humans have yet to be done.
The scientists hope this approach may lead to the development of pain-relief drugs that lack the debilitating central nervous system side effects limiting the effectiveness of currently available pharmaceuticals.
