DOLENE AP-65 vs ROXICET
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
DOLENE AP-65 is a combination of dipyrone (metamizole) and propantheline. Dipyrone is a non-opioid analgesic and antipyretic that acts centrally and peripherally via inhibition of cyclooxygenase and activation of the endocannabinoid system. Propantheline is an anticholinergic agent that inhibits muscarinic acetylcholine receptors, reducing gastrointestinal motility and spasm.
Roxicet is a combination of oxycodone, a full mu-opioid receptor agonist, and acetaminophen, which inhibits cyclooxygenase (COX) enzymes, primarily in the central nervous system, to reduce pain perception and fever.
DOLENE AP-65 (propoxyphene napsylate 100 mg and acetaminophen 650 mg). Adult: 1 tablet orally every 4 hours as needed for pain. Maximum: 6 tablets per day.
1-2 tablets (oxycodone 5-10 mg/acetaminophen 325-650 mg) orally every 4-6 hours as needed for pain; maximum acetaminophen 4000 mg/day (3000 mg/day in high-risk patients).

2-3 hours in adults with normal hepatic function; prolonged in hepatic impairment (up to 5-10 hours) and in neonates (up to 3-5 hours)
Oxycodone: 3-5 hours (immediate-release); prolonged in hepatic/renal impairment. Acetaminophen: 2-3 hours.
Renal: 90% (50% as acetaminophen glucuronide, 30% as sulfate, 5% as cysteine, 3% as unchanged drug, 2% as other metabolites); Fecal: <5%
Primarily renal (90% as glucuronide conjugates, <10% unchanged). Biliary/fecal excretion is minor (<5%).
