DOLENE vs VICODIN ES
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.
Hydrocodone is a mu-opioid receptor agonist; acetaminophen inhibits cyclooxygenase (COX) and modulates descending serotonergic pathways.
50 mg orally every 4-6 hours as needed for pain; maximum 400 mg per day.
Oral: 1 tablet (7.5 mg hydrocodone/300 mg acetaminophen) every 4-6 hours as needed for pain; maximum 6 tablets per day due to acetaminophen limit.

2.5-3.5 hours; prolonged in hepatic impairment (up to 6-8 hours) and in neonates.
Hydrocodone: terminal half-life approximately 3.3-4.5 hours in adults, extended in hepatic or renal impairment. Acetaminophen: terminal half-life about 2-3 hours.
Renal: 70-80% as conjugated metabolites (mostly glucuronides), 5-10% as unchanged drug; Fecal: 5-10%; Biliary: minor.
Hydrocodone: primarily renal (urine) as unchanged drug and metabolites (O-demethylation and 6-keto-reduction products); ~26% excreted unchanged. Acetaminophen: renal (urine), ~85% as glucuronide and sulfate conjugates, ~2% unchanged.
