TLDR Finasteride boosts morphine's pain relief, stops tolerance, and reduces withdrawal in rats.
The study found that finasteride, a 5α-reductase inhibitor, enhanced the pain-relieving effects of morphine, prevented the development of tolerance to morphine, and reduced withdrawal symptoms in rats. This suggests its potential use in pain management and as a treatment for opioid addiction.
