Narcan-resistant fentanyl mixture found in Tulsa has Sedgwick County on alert

WICHITA, Kan. (KAKE)— A dangerous new drug combination discovered in Tulsa is raising concerns among Sedgwick County officials.

Tulsa police say lab tests confirmed five samples containing fentanyl mixed with medetomidine, a veterinary sedative. Because medetomidine is not an opioid, Narcan — the medication used to reverse opioid overdoses — may not counteract its effects.
