DILAUDID-HP vs STADOL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Hydromorphone is a full mu-opioid receptor agonist with high affinity for mu-opioid receptors, producing analgesia, euphoria, and sedation. It also binds to kappa and delta opioid receptors with lower affinity.
Partial agonist at mu-opioid receptors and agonist at kappa-opioid receptors in the CNS, altering pain perception and emotional response to pain.
Initial dose: 0.2-0.6 mg IV/IM/SC every 2-4 hours as needed; usual adult dose: 0.2-0.4 mg IV/IM/SC. Oral: 1-2 mg every 3-6 hours. Dose titration based on pain severity.
Butorphanol tartrate 1-2 mg IV or IM every 3-4 hours as needed for pain; alternatively, 0.5-1 mg IV every 3-4 hours. For nasal spray: 1 mg (one spray) in one nostril, may repeat in 60-90 minutes if needed; then 1 mg every 3-4 hours as needed.

Terminal elimination half-life: 2.3–4 hours. In clinical context, consistent with dosing interval of 4–6 hours for immediate-release formulations; prolonged in hepatic or renal impairment.
Terminal elimination half-life: 2.5-4 hours; clinically, prolonged in hepatic impairment (up to 10-12 hours) and elderly
Renal: predominantly as hydromorphone-3-glucuronide (H3G), unchanged hydromorphone (<6%), and other metabolites. Biliary/fecal: minimal.
Renal: 85-90% as unchanged drug and metabolites (primarily as glucuronide conjugates); Fecal: <10%; Biliary: minimal
