About this study

This randomized clinical study was designed to compare two pain treatment approaches for adults with oral cancer who had moderate to severe pain. Oral cancer pain may occur because of tumor growth, local tissue damage, inflammation, ulceration, or nerve involvement. Standard pain treatment often includes opioid medicines, but these medicines may cause side effects such as sedation, nausea, constipation, dizziness, tolerance, or dependence. In some patients, pain may also have a nerve-related or inflammatory component, where medicines such as pregabalin and naproxen sodium may provide additional benefit.

A total of 98 eligible adult patients with histopathology-confirmed oral cancer and a baseline Visual Analog Scale pain score of 4 or more were included. Patients were randomly assigned into two treatment groups. One group received oral tramadol 50 mg every 4 hours, with dose adjustment according to pain relief and tolerability. The other group received oral pregabalin 75 mg twice daily with naproxen sodium 550 mg twice daily. Both treatments were given for 7 days under clinical monitoring.

Pain intensity was measured using the Visual Analog Scale at baseline, day 3, and day 7. The main outcome was the mean reduction in pain score from baseline to day 7. Effective pain relief was defined as at least 50% reduction in the baseline pain score after 7 days of treatment. Side effects such as sedation, nausea or vomiting, constipation, dizziness, and gastrointestinal discomfort were also recorded. Patient satisfaction with pain control was assessed at the end of treatment.

Group B Pregabalin Plus Naproxen SodiumExperimentalReceived oral pregabalin 75 mg twice daily along with oral naproxen sodium 550 mg twice daily for pain management. Treatment was continued for 7 days with clinical monitoring for pain response and adverse effects.

What is being measured

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

  1. Mean Change in Visual Analog Scale Pain Score From Baseline to Day 7

    Pain intensity was assessed using the Visual Analog Scale, ranging from 0 to 10, where 0 indicated no pain and 10 indicated the worst imaginable pain. The mean change in pain score was calculated by subtracting the day 7 Visual Analog Scale score from the baseline Visual Analog Scale score. A greater positive change indicated greater reduction in pain intensity. The mean change was compared between the tramadol group and the pregabalin plus naproxen sodium group.

    Measured: Baseline and Day 7

Secondary outcomes (2)
  1. Effective Pain Relief at Day 7

    Effective pain relief was defined as at least 50% reduction in the baseline Visual Analog Scale pain score after 7 days of treatment. The proportion of participants achieving effective pain relief was compared between the two treatment groups.

    Measured: Baseline to Day 7

  2. Severity of Adverse Events

    The severity of adverse events was assessed using the Common Terminology Criteria for Adverse Events version 5.0. Events were categorized according to severity grade and compared between the treatment groups.

    Measured: Day 0 to Day 7

Questions about this trial

What is this clinical trial studying?

A study testing Tramadol and Pregabalin + Naproxen Sodium in people with Oral Cancer and Oral Cavity Cancer, run by Mayo Hospital Lahore at 1 site in Pakistan.

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 5 inclusion and 5 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: enrolling by invitation, as of the sponsor's last update on 26 May 2026. 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 Pakistan. 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?

This study is still under way. Results are not available in the source record yet.

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?

Mean Change in Visual Analog Scale Pain Score From Baseline to Day 7 (time frame: Baseline and Day 7). 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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 May 2026.
