Notes: Naloxonazine is a μ-opioid receptor antagonist (Ki = 0.054 nM in a radioligand binding assay).{25533} It is selective for μ-opioid over κ- and δ-opioid receptors (Kis = 11 and 8.6 nM, respectively, in radioligand binding assays) and selectively binds to high-affinity µ1-opioid over μ- and δ-opioid receptors (Kds = 0.1, 2, and 5 nM, respectively).{25533,67381} Naloxonazine (0.16 mg/kg) reverses sufentanil-induced antinociception, as well as hypercapnia and hypoxia, markers of respiratory depression, in rats.{67382} It reduces ethanol self-administration and food intake in rats when administered at a dose of 10 mg/kg.{67383} Naloxonazine (20 mg/kg) inhibits cocaine-induced place preference in rats.{67384}
