Xylazine, isotonitazine new to drug trends, experts say

A box of Narcan sits in the Savage Sisters' community outreach storefront in the Kensington neighborhood of Philadelphia in May. Generically known as naloxone, the medication used revive people who have stopped breathing, doesn’t reverse the effects of xylazine. Philadelphia officials stress that naloxone should still be administered in all cases of suspected overdose, since xylazine is almost always found in combination with fentanyl.

The types of drugs in circulation on the street can ebb and flow, but medical professionals, including Dr. C. Thomas Brophy of the Ellen O’Brien Gaiser Center, are noticing certain new substances rise in popularity.

The medical director of the Butler-based recovery center said people struggling with addiction tend to seek euphoria by what ever means necessary.

“They don’t care so much whether it arrives via morphine, Demerol, Dilaudid, heroin, fentanyl, or the newest synthetic, isotonitazine,” Brophy said. “Many times, regardless of which form of opioid is involved, it is simply referred to as 'dope.’”

Xylazine, or “tranq,” is one such new drug, which Brophy said has been traced back to Puerto Rico, made its way up the East Coast and into Philadelphia before coming to Western Pennsylvania more than a year ago.
