6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Epidural Use in Labor and Delivery Epidural sufentanil was tested in 340 patients in two (one single-center and one multicenter) double-blind, parallel studies.
Doses ranged from 10 to 15 mcg sufentanil and were delivered in a 10 mL volume of 0.125% bupivacaine with and without epinephrine 1:200,
In all cases sufentanil was administered following a dose of local anesthetic to test proper catheter placement.
Since epidural opioids and local anesthetics potentiate each other, these results may not reflect the dose or efficacy of epidural sufentanil by itself.
Individual doses of 10 to 15 mcg sufentanil plus bupivacaine 0.125% with epinephrine provided analgesia during the first stage of labor with a duration of 1 to 2 hours.
Onset was rapid (within 10 minutes).
5 WARNINGS AND PRECAUTIONS • Life-Threatening Respiratory Depression in Patients with Chronic Pulmonary Disease or in Elderly, Cachectic, or Debilitated Patients : Monitor closely, particularly during initiation and titration.
( 5.2 ) • Risks of Skeletal Muscle Rigidity and Skeletal Muscle Movement : Manage with neuromuscular blocking agent.
See full prescribing information for more detail on managing these risks.
( 5.5 ) • Severe Cardiovascular Depression : Monitor during dosage initiation and titration.
( 5.6 ) • Opioid-Induced Hyperalgesia and Allodynia : Opioid-Induced Hyperalgesia (OIH) occurs when an opioid analgesic paradoxically causes an increase in pain, or an increase in sensitivity to pain.
Like all medications, Sufentanil Citrate can cause side effects. However, not everyone who takes this medication will experience them. Many side effects are dose-dependent and may improve as your body adjusts to the medication. Others may require dose adjustment or medical attention.
