None (3) · Active metabolite of tramadol; mu-opioid agonist (1) · Extremely potent GABAA positive allosteric modulator (1) · Extremely potent mu-opioid receptor agonist (1) · GABAA positive allosteric modulator (15) · GABAA positive allosteric modulator (non-benzodiazepine) (3) · GABAA positive allosteric modulator; very long half-life (1) · GABAA potentiator (1) · GABAA potentiator and direct activator (2) · GABAB agonist; GHB receptor agonist (1) · Highly potent mu-opioid receptor agonist (1) · Kappa agonist; mu antagonist (1) · Kappa agonist; mu partial agonist (1) · Kappa agonist; mu partial agonist/antagonist (1) · Melatonin receptor agonist (2) · Mitragynine/7-hydroxymitragynine; mu-opioid partial agonist (1) · Mu-opioid agonist; modulates glutamate AMPA receptors (1) · Mu-opioid agonist; norepinephrine reuptake inhibitor (1) · Mu-opioid receptor agonist (4) · Mu-opioid receptor agonist; fentanyl analogue (1) · Mu-opioid receptor agonist; prodrug (metabolized to morphine) (1) · Mu-opioid receptor agonist; sodium channel blocker (1) · Mu/kappa/delta agonist; NMDA antagonist (1) · Opioid receptor partial agonist/antagonist; toxic alkaloid (1) · Partial mu-opioid receptor agonist; alpha-2 agonist (1) · Phosphodiesterase inhibitor; calcium channel blocker (1) · Positive allosteric modulator of the GABA_A receptor at the benzodiazepine binding site; increases frequency of Cl⁻ channel opening, producing anxiolytic, sedative, hypnotic, anticonvulsant, and skeletal-muscle relaxant effects. (1) · Potent mu-opioid receptor agonist (6) · Prodrug of morphine; mu-opioid receptor agonist (1) · Prodrug; converted to [[Morphine|morphine]] by [[Enzyme:CYP2D6|CYP2D6]] for analgesic action. (1) · Selective GABAA agonist (extrasynaptic delta subunit) (1) · Selective mu-opioid receptor agonist (1) · Ultra-short-acting mu-opioid agonist (1)

None (59) · Mild to moderate pain; cough suppression (low-dose). (1) · No approved medical problem. Encountered as a designer/research benzodiazepine and, increasingly, as an adulterant in illicit opioid supplies. (1)

None (59) · Adult: 15–60 mg every 4 hours as needed. (1) · No medical dose. Active recreational doses reported in the 0.5–1.5 mg range (similar potency to alprazolam). (1)

None (58) · Illicit tablets ("bars"), powders, blotter, occasionally solutions. No pharmaceutical product exists. (1) · Oral tablets 50 mg (ReVia, Depade, generics); Vivitrol extended-release IM suspension 380 mg single-dose vial; Contrave (naltrexone 8 mg + bupropion 90 mg ER tablets); compounded 1, 2, 3, 4.5 mg tablets/capsules for LDN (1) · Tablet (15, 30, 60 mg); oral solution; combination products (with [[Acetaminophen|acetaminophen]] or ibuprofen). (1)

None (58) · 360 mg/day (1) · 50 mg/day oral; 380 mg/4 weeks IM (Vivitrol); 32 mg + 360 mg naltrexone/bupropion daily (Contrave maximum after titration) (1) · N/A (never approved) (1)

None (58) · intramuscular (depot) (1) · intranasal; rectal and IV reported. (1) · Oral (2) · PO (only formulation marketed in the US). (1) · sublingual (1)

None (58) · 30–60 min (PO) (1) · Oral peak plasma 1 hour; therapeutic opioid blockade within hours of first dose. IM Vivitrol: peak plasma 2-3 days; therapeutic blockade through the dosing interval. (1) · ~20–40 min PO; faster sublingual/intranasal. (1)

None (58) · 4–6 hours (1) · 6–10 h subjective; full pharmacologic effect considerably longer. (1) · Oral mu-blockade clinically meaningful for 24-72 hours; IM Vivitrol blockade through 4 weeks. (1)

None (58) · 2.5–3 hours (1) · Estimated ~12–17 h (some sources cite up to ~21 h); active metabolites prolong effect. (1) · Naltrexone parent ~4 hours (oral); 6-beta-naltrexol (active metabolite) ~13 hours. Vivitrol depot terminal half-life 5-10 days with sustained release from microspheres maintaining blockade for the 4-week dosing interval.'"`UNIQ--ref-0000004F-QINU`"' (1)

None (58) · Not formally characterized in humans. (1) · ~5-40% (oral, highly variable due to extensive first-pass metabolism; mean ~5-10% for parent naltrexone with the majority of pharmacologic effect coming from 6-beta-naltrexol). IM Vivitrol bypasses first-pass entirely.'"`UNIQ--ref-00000050-QINU`"' (1) · ~50% (variable, CYP2D6-dependent for analgesic effect). (1)

None (59) · Avoid. Benzodiazepines are associated with neonatal sedation, floppy-infant syndrome, and withdrawal; teratogenic signal weak but non-zero. Designer benzo with no safety data, assume worst-case. (1) · Avoid; risk of neonatal opioid withdrawal with chronic use; UM-mother breastfeeding contraindicated. (1)
