sufentanil SL (Rx)

Severe Acute Pain

Indicated for severe acute pain for which alternative treatments are inadequate

30 mcg SL as needed with a minimum of 1 hr between doses

Not to exceed 360 mcg (12 tablets) daily

Dosage Modifications

Hepatic impairment

• Extensively metabolized in the liver; clearance may decrease with hepatic impairment
• Monitor for adverse events including respiratory depression, sedation, and hypotension in patients with hepatic impairment

Renal impairment

• Excreted by the kidney, with no significant changes noted in patients with mild-to-moderate renal impairment
• Monitor for adverse events including respiratory depression, sedation, and hypotension in patients with severe renal impairment

Dosing Considerations

Limitation of use

• Not for home use or for use in children; discontinue before patient leaves the certified medically supervised healthcare setting
• Not for use >72 hr
• Administered only by a healthcare provider

Safety and efficacy not established

No studies were specifically performed in elderly patients, although 31% of patients were aged ≥65 yr

Adverse events increased with age, including nausea

Owing to increased risk of respiratory depression in elderly patients and the inability to titrate sufentanil SL, monitor closely for signs of CNS and respiratory depression, or consider an alternative medication with available titration

Contraindicated (3)

• alvimopan

  alvimopan, sufentanil SL. receptor binding competition. Contraindicated. Alvimopan is contraindicated in opioid tolerant patients (ie, those who have taken therapeutic doses of opioids for >7 consecutive days immediately prior to taking alvimopan). Patients recently exposed to opioids are expected to be more sensitive to the effects of alvimopan and therefore may experience abdominal pain, nausea and vomiting, and diarrhea. No significant interaction is expected with concurrent use of opioid analgesics and alvimopan in patients who received opioid analgesics for 7 or fewer consecutive days prior to alvimopan.
