DOLENE vs ZOHYDRO ER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Opioid agonist, primarily mu-opioid receptor activation, leading to analgesic and euphoric effects.
Zohydro ER is a pure opioid agonist with relative selectivity for mu-opioid receptors, although it can interact with other opioid receptors at higher doses. Its primary therapeutic action is analgesia via binding to mu-opioid receptors in the central nervous system, leading to activation of descending inhibitory pathways and modulation of pain perception.
50 mg orally every 4-6 hours as needed for pain; maximum 400 mg per day.
Initial: 20 mg orally every 24 hours; titrate in increments of 10-20 mg every 3-7 days as needed; maximum dose 200 mg every 24 hours.

2.5-3.5 hours; prolonged in hepatic impairment (up to 6-8 hours) and in neonates.
Terminal elimination half-life is approximately 10.6 hours (range 8-17 hours) due to extended-release formulation; immediate-release hydromorphone half-life is 2-3 hours. Clinically, steady-state is achieved after 3-5 days of dosing.
Renal: 70-80% as conjugated metabolites (mostly glucuronides), 5-10% as unchanged drug; Fecal: 5-10%; Biliary: minor.
Primarily renal excretion of hydromorphone-3-glucuronide (H3G, ~60%), unchanged hydromorphone (~15%), and other conjugates. Fecal excretion accounts for ~25%.
