About this study

Official title: Duloxetine for Post Operative Analgesia After Modified Radical Mastectomy:A Randomized Controlled Study

The aim of this study is to evaluate the role of duloxetine in controlling pain after radical mastectomy.

Read the detailed description

Inadequate control of postoperative pain is associated with increased length of hospital stay, increased hospital cost, sleep disturbance, depression, functional impairment and affects the quality of life.

Modified is one of the commonly performed procedures which is associated with severe postoperative pain.

Preemptive analgesia is the analgesic treatment initiated before the surgical procedure to prevent central sensitization from the noxious stimuli. Drugs such as gabapentin, pregabalin, serotonin-norepinephrine reuptake inhibitors, dexamethasone, and cyclooxygenase-2 inhibitors have been used for preemptive analgesia.

There are contrary results about the role of duloxetine in mangement of acute postoperative pain.

Arecent meta-analysis was done in 2020 that concluded that the currently available evidence does not support the clinical use of duloxetine for the management of acute postoperative pain,so we will discuss that in this study.

There are many studies that have shown that perioperative use of duloxetine for a few days has a significant effect on reducing postoperative pain and analgesic requirements.

Duloxetine is a dual anti-depressant drug that inhibits the neuronal reuptake of serotonin (5-HT) and norepinephrine (NE) modulating the descending inhibitory pain pathways by increasing the availability of serotonin and norepinephrine. Duloxetine is an approved drug for the treatment of post-traumatic depression, major depression, and generalized anxiety disorder. It is also approved for the treatment of various chronic painful syndromes, including neuropathic pain associated with diabetes, chronic musculoskeletal pain, and fibromyalgia.

The mechanisms of action so far described suggest that duloxetine may be useful as an adjunct in the treatment of acute postoperative pain.

Acetaminophen group, Duloxetine group

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Acetaminophen groupProcedure or surgery

    patients will receive intravenous 500 mg acetaminophen(every 6 hours postoperatively

  • Duloxetine groupProcedure or surgery

    Patients will receive duloxetine 30 mg every 12 hours for 3 days before surgery, 30 mg 2 hours preoperatively and 30 mg 12 hours postoperatively and intravenous 500 mg acetaminophen every 6 hours postoperatively

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Total morphine consumption

    Postoperative Total morphine consumption will be recorded

    Measured: 48 hours postoperatively

Secondary outcomes (5)
  1. First analgesic request

    First analgesic request will be recorded

    Measured: 24 hours postoperatively

  2. Post-operative pain

    Post-operative pain will be assessed by visual analogue score (VAS) from 0-10 scale 0 (no pain) to 10 (the worst imaginable pain) at 2,4,6 h then every 6h

    Measured: 48 hours postoperatively.

  3. Heart rate

    Heart rate will be measured every 30 minutes intraoperative and at 0 hour (direct postoperative) at post anesthesia care unit then at 2,4,6 hours at ward then every 6 hours for 48 hours postoperatively

    Measured: 48 hours postoperatively

  4. Mean arterial blood pressure

    Mean arterial blood pressure will be measured every 30 minutes intraoperative and at 0 hour (direct postoperative) at post anesthesia care unit then at 2,4,6 hours at ward then every 6 hours for 48 hours postoperatively

    Measured: 48 hours postoperatively

  5. Adverse effects

    Hypotension, Bradycardia, nausea, dry mouth,diarrhea, constipation,insomnia, somnolence, fatigue, hyperhidrosis and pruritus will be observed and treated accordingly

    Measured: 48 hours postoperatively

Questions about this trial

What is this clinical trial studying?

A study testing Acetaminophen group and Duloxetine group in people with Modified Radical Mastectomy and Postoperative Analgesia, run by Tanta University at 1 site in Egypt.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 20 Jul 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Dina Elfeky, M.B.B.CH. (0 111 747 2680 ext. +2, dena154452@med.tanta.edu.eg), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Total morphine consumption (time frame: 48 hours postoperatively). It is what the study was designed to measure, not a finding.

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?
