About

The purpose of this study is to determine if treatment with low-dose oral propranolol in the days before and after surgery decrease postoperative pain and improve pain scores.

Full 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.

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Male or female patients age >18 undergoing elective spinal fusion surgery, with plans to remain inpatient for ≥ 48hrs and receive IV or oral opioids;
• Females of child bearing potential must test negative on a pregnancy test at Visit 1 and utilize acceptable means of birth control for the duration of the study;
• Patients must be judged by the study team to be likely to be reliable and to agree to keep all appointments for clinic visits, tests, and procedures required by the protocol;
• Patients must have the ability to fully participate in the informed consent process.

Exclusion criteria

• Disease-related: History of exercise- or exertion-induced asthma or current treatments for asthma; Unstable medical or neurological illness; Heart block greater than first degree (EKG); History of coronary artery disease, or history of congestive heart failure; Baseline heart rate or blood pressure that in the opinion of the investigator would constitute too great a risk when considered in the context of the patient's medical comorbidities and health history; Significant suicidal or homicidal ideation, or current DSM-IV diagnosis of bipolar disorder, schizophrenia or other psychotic disorder, or cognitive disorder due to a general medical condition; History of diabetes
• Exposure-related: History of β-blocker use within six months of enrollment in the trial; Total baseline preoperative opioid consumption greater than 50 oral milligram morphine equivalents (MME) per day; Current use or use within the past two weeks of methadone, levorphanol, buprenorphine, butorphanol, pentazocine, tramadol, nalbuphine, naloxone, or naltrexone.
• Patient characteristics: Female patients who are pregnant or breast-feeding; Known allergy to study medication; Alcohol/substance abuse within past six months; Ongoing or anticipated disability compensation or litigation issues, in the best judgement of the investigator; Presence of any factors/conditions, medical or other, that in the judgment of the investigator may interfere with performance of study outcome measures, such as treatment-refractory history; Non-ambulatory or require the use of crutches or a walker; No access to a telephone

Propranolol treatment

Experimental group

Description:

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.

Treatment:

Drug: Propranolol Hcl 40mg Tab

Placebo

Placebo Comparator group

Description:

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.

Treatment:

Drug: Placebo oral tablet
