Naltriben is a potent and selective antagonist for the delta opioid receptor, which is used in scientific research. It has similar effects to the more widely used δ antagonist naltrindole, but with different binding affinity for the δ1 and δ2 subtypes, which makes it useful for distinguishing the subtype selectivity of drugs acting at the δ receptors.[1] It also acts as a κ-opioid agonist at high doses.[2]
