June 30, 2026 updated by: Case Western Reserve University

Exparel Versus Bupivacaine in Post-operative Pain Control Following Bilateral Third Molar Extractions: A Single-blind Randomized Clinical Trial

This is a prospective, randomized study to evaluate anaesthetic parameters, postoperative analgesia and oral analgesic consumption comparing exparel (liposomal bupivacaine) vs. standard bupivacaine

Completed

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

The main purpose of this prospective, randomized study was to evaluate anaesthetic parameters, postoperative analgesia and oral analgesic consumption comparing exparel (liposomal bupivacaine) vs. standard bupivacaine. At the end of the third molar extraction surgical procedure and at least fifteen minutes following the most recent administration of 2% lidocaine with 1:100,000 epinephrine (routine for this procedure), patients will, at random, receive mandibular and maxillary infiltrations with 3mL of 1.3% liposomal bupivacaine (Exparel) or with standard 3mL standard bupivacaine. Electronic home questionnaires will be completed by the patient following the procedure for 96 hours to evaluate these clinical parameters

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Male and nonpregnant female adults (≥18 years of age) with American Society of Anesthesiologists physical status classification 1, 2, or 3 who were scheduled to undergo bilateral third molar extraction (extraction of all 4 third molars) under local anesthesia and general anesthesia Study participants were required to have full or partial bony impaction of both mandibular third molars.

Exclusion Criteria:

  • history of allergy or contraindication to amide-type local anesthetics, epinephrine, or opioids a history of any disease or condition or recent use of any drug that, in the opinion of the investigator, might increase the risk of surgery or interfere with study evaluations any use of long-acting opioids, nonsteroidal anti-inflammatory drugs, aspirin, or acetaminophen within 3 days before screening or use of opioids within 24 hours of screening Patient that is pregnant or suspected to be pregnant Adults that cannot speak English, adults that are unable to consent on their own, or persons that are listed as vulnerable individuals will not be part of the study

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
Post Operative Pain Intensity (Visual Analog Scale VAS)
Time Frame: Twice daily (morning and evening) from 0-96 hours post-operatively
Post operative pain was assessed using 0-10 Visual Analog Scale (VAS) where 0 indicates no pain and 10 indicates worse imaginable pain. Patients recorded pain score twice daily (morning and evening) for four consecutive post operative days using a standardized at home questionnaire
Twice daily (morning and evening) from 0-96 hours post-operatively

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
Post Operative NSAID/Acetaminophen Consumption
Time Frame: Daily from 0 to 96 hours post-operatively
Post operative analgesic consumption was recorded using a standardized at home questionnaire. Patients document the number of NSAIDS (Ibuprofen 600mg) and Acetaminophen tablets taken daily for four consecutive postoperative days.
Daily from 0 to 96 hours post-operatively
Post Operative Opioid Consumption (Hydrocodone-Acetaminophen 5/325) Use
Time Frame: daily from 0 to 96 hours post-operatively
post operative opioid consumption was recorded using a standardized at home qusetionnaire. patients documented the number of (Hydrocodone-Acetaminophen 5/325) tablets taken daily for four consecutive postoperative days
daily from 0 to 96 hours post-operatively
