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

This study is a randomized, double-blind, placebo controlled clinical trial.The main purpose of this study is to determine if postsurgical opioid use and pain scores are decreased with oral Propranolol treatment. The treatment period will last for six days and the observation period will last for three months. Effectiveness of treatment will be assessed by means of post-operative opioid consumption as primary outcome measure.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Propranolol treatment

Subjects randomized to the propranolol treatment arm will be administered propranolol 40mg BID for three days prior to surgery, 40mg BID the day of surgery and on post-operative days 1 and 2. Subjects and researchers will be blinded and will not know if propranolol or placebo control is administered.

Patients will be evaluated for opioid usend pain scores at 24 hrs, 48 hrs, 1 week, 4 weeks, and 12 weeks post-op.

Blood will also be obtained pre-operatively, 8 hours and 24 hours post-operatively to measure the level of inflammatory markers. We will use these samples to evaluate if treatment with propranolol decreases the levels of inflammatory markers, and if this correlates to decreased opioid use and pain scores post-operatively.

All other pre-, intra-, and post-operative interventions will be equivalent between the experimental and placebo groups, and this study's interventions will not affect surgical management.
Drug: Propranolol Hcl 40mg Tab
40mg PO BID for the three days prior to surgery, 40mg PO BID the day of surgery and on post-op days 1 and 2.
Other Names:
  • Inderal
  • CAS No 525-66-6
  • DIN: 00496499
Placebo Comparator: Placebo

Subjects randomized to the placebo treatment arm will be administered placebo tablets with the same schedule as propranolol in the experimental arm. Subjects and researchers will be blinded and will not know if propranolol or placebo control is administered.

Patients will be evaluated for opioid use and pain scores at 24 hrs, 48 hrs, 1 week, 4 weeks, and 12 weeks post-op.

Blood will also be obtained pre-operatively, 8 hours and 24 hours post-operatively to measure the level of inflammatory markers. We will use these samples to evaluate if treatment with propranolol decreases the levels of inflammatory markers compared to placebo, and if this correlates to decreased opioid use and pain scores post-operatively.

All other pre-, intra-, and post-operative interventions will be equivalent between the experimental and placebo groups, and this study's interventions will not affect surgical management.
Drug: Placebo oral tablet
Placebo tablets administered with the same schedule of Propranolol tablets

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
Acute postoperative opioid use at 24 hours
Time Frame: 24 hours postoperatively
Total opioid use from 0 to 24 hours post-op will be quantified. Opioid doses administered via all routes will be converted to standard oral morphine equivalents (OME).
24 hours postoperatively

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
Acute postoperative opioid use at 48 hours
Time Frame: 48 hours postoperatively
Total opioid use from 24 to 48 hours post-op will be quantified. Opioid doses administered via all routes will be converted to standard oral morphine equivalents (OME).
48 hours postoperatively
Sub-acute postoperative opioid use at 1 week
Time Frame: 1 week postoperatively
Patient reported current opioid use for the prior 24 hours will be quantified at 1 week post-op. Opioid use will be converted to standard oral morphine equivalents (OME).
1 week postoperatively
Sub-acute postoperative opioid use at 4 weeks
Time Frame: 4 weeks postoperatively
Patient reported current opioid use for the prior 24 hours will be quantified at 4 weeks post-op. Opioid use will be converted to standard oral morphine equivalents (OME).
4 weeks postoperatively

12 weeks postoperatively
Acute postoperative pain scores at 24 hours
