Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Hydrocodone is a mu-opioid receptor agonist that inhibits ascending pain pathways and alters pain perception; acetaminophen inhibits cyclooxygenase (COX) enzymes, primarily in the CNS, reducing prostaglandin synthesis and fever.
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.
1 tablet orally every 4 to 6 hours as needed; maximum 6 tablets per day.
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.

Hydrocodone: Terminal half-life 3.8-7.2 hours (mean 5.6 h). Acetaminophen: 1.5-2.5 hours (therapeutic) but prolonged to >4 hours in overdose with hepatotoxicity risk.
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)
Hydrocodone: Renal elimination of metabolites (hydromorphone, norhydrocodone) and unchanged drug accounts for ~60-90% of clearance. Acetaminophen: ~85% of dose is excreted in urine as glucuronide and sulfate conjugates; 5-10% unchanged; 2-5% as mercapturate.
Renal: 90% (50% as acetaminophen glucuronide, 30% as sulfate, 5% as cysteine, 3% as unchanged drug, 2% as other metabolites); Fecal: <5%
