U-48800 is an opioid analgesic which has been sold as a designer drug. Unlike U-47700, it is primarily active as a kappa opioid receptor agonist with only moderate affinity at the mu opioid receptor. Nevertheless, it has still appeared on the recreational drug market, often as a component of combinations with other drugs, and has been linked to numerous drug overdose cases.[1][2][3][4][5]
