Condition(s) targeted: Pain; Breast Diseases

Intervention: acetaminophen plus codeine (Drug); acetaminophen plus ibuprofen (Drug)

Phase: Phase 3

Status: Completed

Sponsored by: Nova Scotia Health Authority

Summary

Current standard of care for post-operative analgesia after breast surgery in CDHA is Tylenol #3 (300 mg acetaminophen, 30 mg codeine, 15 mg caffeine per tablet). We are proposing to test the analgesic efficacy of acetaminophen plus ibuprofen against Tylenol #3 in patients undergoing outpatient breast surgery.

Clinical Details

Official title: A Randomized Controlled Trial Comparing Combination Therapy of Acetaminophen Plus Ibuprofen Versus Tylenol #3 for the Treatment of Pain After Breast Surgery.

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Treatment

Primary outcome:

VAS Scores.

maximum VAS scores.

Likert scores.

Patient satisfaction with analgesic regimen.

Treatment failures-inadequate pain relief or inability to tolerate side effects.

Time to stopping medication.

Secondary outcome:

Total Pain relief (TOTPAR).

Sum of pain intensity differences (SPID).

Amount of medication used.

Incidence of side effects.

Compliance with regimen.

Detailed description: Block randomization will be used to randomize patients to one of two combinations. Group A will receive capsules containing 650 mg Acetaminophen plus 400 mg Ibuprofen. Group B will receive capsules containing 600 mg Acetaminophen, 15 mg caffeine and 60 mg codeine. Capsules are placed in identical dossettes containing a seven day supply. Patients are instructed to start taking their medications post-op and continue until they are pain free. All participants are given a series of blank Visual Analogue scales and Likert scales and instructed to record their level of pain intensity and pain relief four times per day for the entire week. Peri-operative pain management will be standardized. Patients will not receive pre-operative analgesics. Intra-operative analgesia will be intravenous opioids as selected by anaesthesiology. No local/regional anaesthesia will be used. Intravenous ketorolac will not be allowed for trial participants. All patients will receive intravenous opioid and anti-emetic if required in PACU. Any patients with peri-operative complications or other problems requiring admission or alternative analgesics will be excluded.
