Cychlorphine
Aliases: Cychlorophine, N-propionitrile chlorophine
Summary
Extremely limited pharmacological data; field samples frequently contain co-contaminants including xylazine or chlorphine. Standard fentanyl test strips yield false-negatives for benzimidazolone opioids. Naloxone may have reduced effectiveness for reversal of toxicity.
