Pharmacokinetics & Dosing Strategy

Bioavailability: ~10% orally; food increases Cₘₐₓ by ~50%, so tablets should be taken 1 hour before or 2 hours after meals

Onset & Duration: Extended-release provides peak plasma levels in ~2.5–4 hours, lasting approximately 12 hours per dose

Initial dosing: Opioid-naïve adults typically start with 5 mg every 12 hours, adjusted based on prior opioid use (e.g., 50% conversion from other opioids)

Titration: Increase in 5–10 mg increments every 3–7 days to balance efficacy and safety

⚠️ Safety Profile & Clinical Considerations

Potency: Approximately three times stronger than oral morphine and twice that of oxycodone

Risks include:

Respiratory depression, hypotension, CNS sedation (especially with alcohol or sedatives)

Constipation, ileus, and cholestatic effects—requires proactive bowel management .

Addiction and misuse—high dependency potential demands secure storage and adherence to prescription .

Special populations:

Avoid in severe hepatic or renal impairment; elderly require cautious dosing due to slower clearance and higher plasma levels .
