Overdose drug shows promise as stroke treatment

Naloxone, the life-saving drug used to treat opioid overdose, is shown to reduce brain inflammation in the aftermath of stroke in male rats. The preclinical research, by scientists at the NIDA Intramural Research Program, partnering with investigators from Colorado, Taiwan and Finland, lays the groundwork for developing the first drug to promote recovery from ischemic stroke, a leading cause of adult disability.
