Oliceridine hydrochloride (TRV130 hydrochloride) is a G protein biased μ opioid receptor agonist with an pEC50 of 8.1.

Oliceridine (TRV130) elicits robust G protein signaling, with potency and efficacy similar to morphine, but with far less β-arrestin recruitment and receptor internalization[2].

Oliceridine (TRV130) treatment produces robust antinociception, complete inhibition of gastrointestinal function, and weak abuse-related effects in mice[1]. Oliceridine (TRV130) displays an ED50 of 0.9 mg/kg in an analgesic assay. Oliceridine analgesia is reversible in mice by administration of 3 mg/kg naloxone s.c. 15 minutes after Oliceridine dosing. In the rat 52°C hot plate, Oliceridine is 10-fold more potent than morphine with ED50 of 0.32 and 3.2 mg/kg, respectively. Oliceridine (0.3 mg/kg, s.c.) possesses an improved therapeutic index of analgesia to constipation relative to morphine in mice[2]. Oliceridine (TRV130; 1.2 mg/kg, s.c.) significantly depresses respiration of mice[3].
