About this study
Official title: Duloxetine Potentiates the Analgesic Efficacy of Intrathecal Morphine in Major Abdominal Cancer Surgery
Duloxetine is a serotonin-norepinephrine reuptake inhibitor primarily used for treatment of major depression and anxiety. Duloxetine also has been used in the treatment of chronic pain conditions, such as osteoarthritis and musculoskeletal pain. There are few studies examining its effect for acute pain. The objective of this study is to evaluate the analgesic effect of duloxetine combined with intrathecal morphine for patients subjected to major abdominal cancer surgery

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Duloxetine 60mgDrug
Patients will receive duloxetine, 60 mg tablet 2 hour before operation and will be anesthetized by combined spinal-general anesthesia that includes: spinal anesthesia with morphine 0.3 mg delivered in L4-5 inter spinous space.
General anethseia: Induction of anesthesia was done by intravenous fentanyl, 2 µg / kg and propofol 1 - 2 mg / kg. Endotracheal intubation was achieved by cis-atracurium, 0.15 mg / kg. Maintenance of anesthesia was done by isoflurane and cis-atracurium, 0.03 mg / kg on demand. Additional intraoperative analgesia was consisted of administration of intravenous boluses of fentanyl, 50 µg according to the attending anesthesiologist's decision. At the end of surgery, muscle relaxation was reversed using neostigmine 0.05 mg / kg and atropine 0.01 mg / kg.
placeboDrug
Patients will receive placebo tablet 2 hour before operation and will be anesthetized by combined spinal-general anesthesia that includes: spinal anesthesia with morphine 0.3 mg delivered in L4-5 inter spinous space.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
time to first analgesic request (time frame: 48 hours postoperatively). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
