LERITINE vs OXYCONTIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
LERITINE (anileridine) is a synthetic opioid analgesic that acts as a mu-opioid receptor agonist, modulating pain perception and emotional response to pain.
Oxycodone is a full opioid agonist with relative selectivity for the mu-opioid receptor, although it can bind to other opioid receptors at higher doses. The principal therapeutic action of oxycodone is analgesia. Like all full opioid agonists, there is no ceiling effect for analgesia with oxycodone. Clinically, dosage is titrated to provide adequate analgesia and may be limited by adverse reactions, including respiratory and CNS depression.
Adults: 25-50 mg orally every 6 hours as needed for pain; not to exceed 200 mg/day.
10 mg orally every 12 hours; titrate based on pain severity and prior opioid exposure.

2-3 hours (terminal half-life in adults; may be prolonged in hepatic impairment or elderly, dosing adjustments recommended)
4.5-5.0 hours (immediate-release); controlled-release OXYCONTIN has an apparent half-life of 4.5-8.7 hours. Terminal half-life is ~3.5-4 hours for immediate-release, reflecting context-sensitive elimination.
Renal (70-90% as unchanged drug and metabolites); biliary/fecal (10-30%)
Primarily renal (90% as metabolites, 10% unchanged). Also biliary/fecal (10%).
