ROXILOX vs VICODIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Roxilox is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis and thereby alleviating pain and inflammation.
VICODIN (hydrocodone/acetaminophen) is a combination opioid agonist and analgesic. Hydrocodone acts on mu-opioid receptors in the CNS to alter pain perception and response; acetaminophen inhibits cyclooxygenase (COX) activity, likely in the CNS, reducing prostaglandin synthesis and providing antipyretic effects.
10 mg orally once daily, with or without food.
1-2 tablets (hydrocodone 5-10 mg and acetaminophen 300-325 mg) orally every 4-6 hours as needed for pain; maximum daily acetaminophen dose 4 g.

Terminal elimination half-life 4.5 hours; prolonged to 18-24 hours in severe renal impairment (CrCl <30 mL/min)
Hydrocodone: 3.8-6.4 hours (terminal); Acetaminophen: 2-3 hours (terminal). Clinically, steady-state achieved in 1-2 days.
Renal (70-80% unchanged), biliary/fecal (15-20%), remainder metabolized
Hydrocodone: primarily renal (~60% as metabolites, 12% unchanged); minor biliary. Acetaminophen: renal (90-100% as metabolites, 2-4% unchanged).
