DOLENE AP-65 vs PAPA-DEINE #3
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.
Acetaminophen produces analgesia and antipyresis via central COX-2 inhibition and activation of descending serotonergic pathways. Codeine is a prodrug converted to morphine, a mu-opioid receptor agonist, which inhibits ascending pain pathways and alters pain perception.
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 orally every 4-6 hours as needed for pain, not to exceed 12 tablets in 24 hours. Each tablet contains acetaminophen 300 mg, codeine phosphate 30 mg.

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)
Codeine: 2.5-3 hours; Acetaminophen: 2-3 hours; Morphine (active metabolite): 2-3 hours. In hepatic impairment, codeine half-life may extend to 4-6 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% as morphine, codeine, and norcodeine). Biliary/fecal elimination accounts for <5%.
