Narcotic vs. Non-narcotic Pain Study Protocol

Phase 4

Completed

• Conditions: Carpal Tunnel
• Interventions: Drug: Narcotic; Drug: non-narcotic

• Registration Number: NCT01974609
• Lead Sponsor: Horizon Health Network

Brief Summary

The purposes of this noninferiority randomized clinical trial are to:

1. determine whether the most commonly used commonly used non-narcotic analgesic (ibuprofen 600 mg + acetaminophen 325 mg) provides pain relief that is not unacceptably worse than the most commonly prescribed narcotic containing analgesic (hydrocodone 5 mg. + acetaminophen 325 mg, equivalent to Norco 5/325) in patients undergoing carpal tunnel release.

2. Determine whether the following covariates affect pain level following surgery or medication usage: gender, country (US/Canada), pre-operative CTS symptoms, site, workers compensation status and employment status (employed/self-employed/unemployed-able to work/unemployed-unable to work)

Detailed Description

Participants will be provided with forms by site coordinators and will be provided in person instruction on how to fill out the pain intensity scores, the pain interference scores, the pain medication diary, and the final pain relief assessment form.

Medications will be identified only by number and will be available to the participant after standard instruction on use of medications is provided by the surgeon or research associate. Patients will be instructed - verbally and written - to take the study medication (2 capsules per dose) up to four times per day as needed for pain for 1 week or until pain free.

If patients experience intolerable discomfort, they will be able to contact personnel (24 hours on call) associated with the study to receive an alternate analgesic. The surgeon will determine if the patient is taking the maximum dose and then prescribe additional study drug or a non-study drug as an alternative. If the patient receives pain medication outside of the study protocol, the medication will be recorded, this will be recorded as a protocol violation. If this occurs in more than 20 people during the trial a per-protocol and efficacy analysis will be considered.

Participants will return to see the surgeon or designate between post-operative day 7 and 14 to return their diary, unused medication, and post-operative pain satisfaction survey. Participants will be specifically asked about: any adverse events, compliance with the program and the reason for any deviation and any other analgesic medication taken during the course of the study.

Arm && Interventions

Group	Intervention	Description
Narcotic	Narcotic	Hydrocodone + acetaminophen 4 times per day 1 week after surgery
non-narcotic	non-narcotic	ibuprofen + acetaminophen 4 times per day 1 week after surgery

Primary Outcome Measures

Name	Time	Method
Pain relief	7-15 days	1. Determine whether the most commonly used nonnarcotic analgesics (ibuprofen 600 mg + acetaminophen 325 mg) provide pain relief that is not unacceptably worse than the most commonly prescribed narcotic containing analgesic (hydrocodone 5 mg + acetaminophen 325 mg, equivalent to Norco® 5/325) in patients undergoing carpal tunnel release.
