NORCET vs OXAYDO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Combination analgesic: hydrocodone acts as a μ-opioid receptor agonist; acetaminophen inhibits cyclooxygenase (COX) and modulates endocannabinoid system, exerting central analgesic and antipyretic effects.
Oxycodone is a full opioid agonist with relative selectivity for mu-opioid receptors, although it can bind to kappa-opioid receptors at higher doses. The principal therapeutic action of oxycodone is analgesia. Like all full opioid agonists, there is no ceiling effect to analgesia for oxycodone.
1-2 tablets (containing paracetamol 325 mg and tramadol 37.5 mg) orally every 4-6 hours as needed for pain, maximum 8 tablets per day.
Oral, 5-10 mg every 4-6 hours as needed for pain; maximum 60 mg per day.

2-4 hours (terminal); prolonged in hepatic impairment (up to 8-10 hours) and elderly
Terminal elimination half-life is 3.5-5.5 hours for immediate-release oxycodone; clinically dose every 4-6 hours for sustained analgesia.
Renal: ~60% unchanged; hepatic metabolism to inactive glucuronide conjugates; biliary/fecal: <5%
Primarily renal as unchanged drug and metabolites; ~90% excreted in urine (approx 10% unchanged oxycodone, rest as noroxycodone and oxymorphone conjugates) and <10% in feces via biliary elimination.
