Agonist binding couples the receptor to inhibitory Gi\u002FGo proteins, which suppresses adenylate cyclase and inhibits N-type and L-type calcium channels; mu-mediated inhibition of voltage-gated calcium channels on central presynaptic terminals of primary afferent nociceptors is thought to be a primary mechanism of analgesia at the spinal level, and the mu receptor is the main physiological target of most clinically important opioid analgesics. This class holds the opioid agonists whose effect is not limited by a ceiling: the FDA-approved label for buprenorphine, a partial agonist, records that compared with full opioid agonists such as methadone and hydromorphone, sublingual buprenorphine produces typical opioid agonist effects which are limited by a ceiling effect, and that because of its partial agonist properties buprenorphine may precipitate opioid withdrawal in people dependent on full opioid agonists. As MED-RT populates the class its members are morphine, hydromorphone, oxycodone, oxymorphone, fentanyl and the other fentanils, codeine, hydrocodone, levorphanol, meperidine and tramadol.",[14,20,24],{"claims":15,"source":16,"licence":17,"source_url":18,"retrieved_at":19},"Opioid receptor as GPCR for endogenous opioids; coupling to pertussis toxin-sensitive Gi\u002FGo proteins, inhibition of adenylate cyclase and of N-type and L-type calcium channels; OPRM1 as the main physiological target for most clinically important opioid analgesics and inhibition of presynaptic voltage-gated calcium channels as a primary mechanism of spinal analgesia.","UniProtKB P35372","not stated on source page","https:\u002F\u002Frest.uniprot.org\u002Funiprotkb\u002FP35372.json","2026-09-19",{"claims":21,"source":22,"licence":17,"source_url":23,"retrieved_at":19},"'Comparisons of buprenorphine to full opioid agonists such as methadone and hydromorphone suggest that sublingual buprenorphine produces typical opioid agonist effects which are limited by a ceiling effect.' and 'Because of the partial agonist properties of buprenorphine, [the product] may precipitate opioid withdrawal signs and symptoms in such persons' (persons dependent on full opioid agonists).","DailyMed SPL - Buprenorphine and naloxone sublingual tablets","https:\u002F\u002Fdailymed.nlm.nih.gov\u002Fdailymed\u002Fservices\u002Fv2\u002Fspls\u002F4124c4ad-ef62-4c95-8e57-0d843862ae71.xml",{"claims":25,"source":26,"licence":17,"source_url":27,"retrieved_at":19},"Class membership: 52 ingredients including morphine, hydromorphone, oxycodone, oxymorphone, fentanyl, alfentanil, sufentanil, remifentanil, codeine, dihydrocodeine, hydrocodone, levorphanol, meperidine, tramadol.","RxNav RxClass class members (MED-RT), classId N0000175684","https:\u002F\u002Frxnav.nlm.nih.gov\u002FREST\u002Frxclass\u002FclassMembers.json?classId=N0000175684&relaSource=MEDRT&rela=has_MoA",[29,33],{"id":30,"documentId":31,"slug":32,"name":32,"active_ingredient":11,"dosage_form":11,"administration_route":11},1697,"s63sdqeevjm6im5eaf8ihhui","fentanyl",{"id":34,"documentId":35,"slug":36,"name":37,"active_ingredient":37,"dosage_form":11,"administration_route":11},1537,"fpj0oy47v7pnc99uvd1a97sb","tramadol","Tramadol",[]]
