About this study

Official title: Comparison of Two Combinations of Opioid and Non-opioid Analgesics for Acute Periradicular Abscess: A Randomized Clinical Trial

Aim: The aim of this study was to compare the analgesic efficacy of two combinations of opioid and non-opioid analgesics for acute periradicular abscesses.

Methodology: This study included 24 patients who sought emergency care in a Brazilian dental school. The patients were randomly divided into two groups: Codeine/Acetaminophen - oral prescription of codeine (30 mg) plus acetaminophen (500 mg), every 4 h, for 3 days or Tramadol/Acetaminophen - oral prescription of tramadol hydrochloride (37.5 mg) plus acetaminophen (500 mg) on the same schedule. Patients recorded pain scores in a pain diary 6, 12, 24, 48, and 72 h after treatment, using the Visual Analogue Scale.

Being tested
Fixed-dose oral tablet of codeine/ acetaminophen every 4 hours for 3 days, Fixed-dose oral tablet of tramadol/ acetaminophen every 4 hours for 3 days

Questions about this trial

What is this clinical trial studying?

A study testing Fixed-dose oral tablet of codeine/ acetaminophen every 4 hours for 3 days and Fixed-dose oral tablet of tramadol/ acetaminophen every 4 hours for 3 days in people with Periapical Abscess, run by Federal University of Rio Grande do Sul.

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 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Reduction of pain scores over time. (time frame: 0, 6, 12, 24, 48 and 72 h after first dose administration). 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?
