Summary
This study looked at whether adding guanfacine (a blood pressure medicine) to morphine could reduce pain sensitivity and tolerance in people with chronic neck or back pain. The study planned to enroll 137 adults who had not taken opioids recently. However, the study was terminated early, so results are limited.
