Efficacy of Lidocaine Patch in Acute Musculoskeletal Pain in the Emergency Department

March 3, 2024 updated by: Stahl, Jennifer, East Carolina University

Efficacy of Lidocaine Patch in Acute Musculoskeletal Pain in the Emergency Department: A Prospective Randomized Controlled Study

This study evaluates the addition of a lidocaine patch to ibuprofen in the treatment of acute musculoskeletal pains. Half of the participants will get only ibuprofen for their pain, while other half will receive lidocaine patch plus the ibuprofen. After addition of the pain medications, the participants will be followed for their pain scores and return visits.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Ibuprofen and other nonsteroidal antiinflammatory pain medications have been traditionally used for relief of mild to moderate acute musculoskeletal pains. However, if this medication did not work, a different modality for pain control would be added to the original regimen. In recent times, lidocaine patch has been introduced as a separate modality for pain control. This medication is thought to help by selectively inhibiting voltage-gated sodium channels in nociceptors involved in pain response. Given the separate modality, it would be prudent to see whether the addition of lidocaine patch to the ibuprofen would help relieve the pain more so than the antiinflammatory-only regimen.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Numerical Pain Rating Scale
Time Frame: 60 minutes
Change in self-reported pain intensity level. Baseline will be prior to intervention, and change will be assessed 60 minutes after intervention. Each item is scored 0-10 (0=No pain, 10= Worst pain possible). Higher number is worse outcome while lower number is better outcome.
60 minutes

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Participants With a Return Visit for Same Chief Complaint
Time Frame: 1 week
Questionnaire (Yes or No) of whether a return visit to either the emergency department or primary care offices occurred within 1 week for same chief complaint from the initial visit
1 week
