SCH-221510 is an experimental opioid drug. It has potential as an analgesic and as a treatment to addiction of certain drugs.

Mechanism of action

Most opioid analgesics act through delta, mu and kappa opioid receptors, however, SCH-221510 is instead an agonist at the nociceptin receptor.^[1]

Analgesic effects

Classical opioid analgesics (such as morphine) usually have effects such as constipation, hypoventilation and addiction.^[2] However, by acting through a different receptor, SCH-221510 seems to be lacking the undesirable effects of morphine at equianalgesic doses.^[1] This suggests that SCH-221510 could be a better opioid than the currently available opioid pain medications, by having less side effects.

Treatment of drug addiction

SCH-221510 might be an option in the treatment of certain drug addictions: it is able to decrease ethanol self-administration^[3] and was able to decrease self-administration of a fentanyl analogue in a study,^[4]
