Comment: Naldemedine (S-297995) is a dual μ/δ opioid receptor antagonist, designed to act peripherally (peripherally acting mu-opioid receptor antagonist or PAMORA) [1]. It is used clinically for its ability to counteract opioid agonist-induced adverse effects such as constipation, nausea, and vomiting. Naldemedine was developed by Shionogi Inc. It is the compound claimed in patent WO2013172297 with formula IA (17-(cyclopropylmethyl)-6,7-didehydro-4,5α-epoxy-3,6,14-trihydroxy-N-[2-(3-phenyl-1,2,4-oxadiazol-5-yl)propan-2-yl]morphinan-7-carboxamide 4-methylbenzenesulfonic acid) [2].
