U-47700 is an agonist of the μ-opioid receptor (K i 11.1 ± 0.4 nM) and possesses significantly lower affinity for the κ-opioid receptor (K i = 287 ± 24 nM) and δ-opioid receptor (K i = 1220 ± 82 nM). U-47700 is approximately 10-fold more potent than morphine in rats, although the binding of U-47700 is 2–4 times weaker than morphine at ...

The opioid epidemic took hold in the U.S. in the 1990s. Percocet, OxyContin and Opana became commonplace wherever chronic pain met a chronic lack of access to quality health care, especially in Appalachia. The Centers for Disease Control and Prevention calls the prescription opioid epidemic the worst of its kind in U.S. history.
It showed affinity values (K i) of 0.051 nM for the μ-opioid receptor, 4.7 nM for the δ-opioid receptor, and 13 nM for the κ-opioid receptor in rat brain. [9] Thus, carfentanil displayed 90- and 250-fold selectivity for the μ-opioid receptor over the δ-opioid receptor and the κ-opioid receptor, respectively. [ 9 ]
