HMN 2025: What is the promising remedy for fentanyl-xylazine overdoses

Researchers at Marshall University have developed a promising remedy technique to deal with overdoses involving fentanyl and the veterinary sedative xylazine, a mix more and more linked to extreme well being problems and lowered effectiveness of ordinary overdose reversal brokers.

In a brand new study published within the Journal of Translational Research, Michael Hambuchen, PharmD, Ph.D., affiliate professor on the Marshall University School of Pharmacy, and pharmacy graduate pupil Jyostna Yalakala, BVSc, MS, in collaboration with Marshall University Joan C. Edwards School of Medicine scientific researcher Todd Davies, Ph.D., affiliate director of analysis and improvement within the Division of Addiction Sciences, and dependancy medication fellowship crew, report that combining naloxone with the investigational drug atipamezole dramatically improves restoration outcomes in animal models of fentanyl-xylazine overdose.

“Adding even a low dose of atipamezole—already examined safely in people for different indications—to naloxone quickly restored consciousness in rats uncovered to fentanyl and xylazine,” mentioned Hambuchen, senior creator of the research. “We additionally noticed enhancements in coronary heart fee, blood glucose and physique temperature, that are all severely disrupted by this harmful drug mixture.”

Xylazine, a veterinary tranquilizer not accepted for human use, is more and more discovered as a contaminant in illicit fentanyl provides. The mixture leads to profound sedation, impaired respiration, dangerously low heart rate, lowered physique temperature and elevated blood glucose, and power use is related to severe pores and skin ulcers. Compounding the hazard, xylazine is just not an opioid and is subsequently proof against reversal by naloxone alone.

“The collaboration on this study between Addiction Sciences and the School of Pharmacy represents the sort of translational analysis that bridges laboratory science with real-world scientific wants,” Davies mentioned. “By replicating advanced overdose situations within the lab, Marshall University is advancing potential remedy methods with direct relevance to West Virginia and past.”
