Effect of Propranolol on the Autonomic Nervous System and Muscle Pain

March 23, 2012 updated by: University of Aarhus

Effects of a Low-dose Propranolol on a Stress Induced Autonomic Response and on Muscle Pain

The project's primary purpose is to test the hypothesis that oral administration of a low single dose of β-antagonist propranolol (40 mg) reduces pain sensitivity in patients with masticatory muscle pain.

Study Overview

Status

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Anticipated)

Enrollment

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

18 years to 60 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

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
Pain intensity
Time Frame: Participants will be asked to score their actual pain level in both of the two experimental sessions they will participate in; an expected average of two weeks between the two sessions
Numeric Rating Scale 0-10
Participants will be asked to score their actual pain level in both of the two experimental sessions they will participate in; an expected average of two weeks between the two sessions

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
Haemodynamic parameters
Time Frame: Participants will be monitored during the entire session in both of the two experimental sessions they will participate in; an expected average of two weeks between the two sessions
Monitoring of pulse and blodpressurevariability, respiration, baroreceptor sensitivity, measured non-invasively by Task Force Monitor.
Participants will be monitored during the entire session in both of the two experimental sessions they will participate in; an expected average of two weeks between the two sessions

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
