NFEPP (N-(3-fluoro-1-phenethylpiperidin-4-yl)-N-phenylpropionamide) is an analgesic opioid chemical, similar in structure to fentanyl, designed in 2016 by Spahn et al. from Free University of Berlin to avoid the standard negative side effects of opiates, including opioid overdose, by only targeting inflamed tissue.
