SR-17018 is a drug which acts as a biased agonist at the μ-opioid receptor, selective for activation of the G-protein signalling pathway over β-arrestin 2 recruitment. In animal studies it produces analgesic effects but with less respiratory depression and development of tolerance than conventional opioids.[1][2][3][4]
