We aren't mDs. Always confer with your doctor on Local Flurbiprofen to Treat Pain Following Wisdom Tooth Extraction conditions. Clinical Trials Search.org is a website devoted to listing clinical research studies in human subjects. Local Flurbiprofen to Treat Pain Following Wisdom Tooth Extraction Clinical research trials and Local Flurbiprofen to Treat Pain Following Wisdom Tooth Extraction healthcare trials occur in a lot of of places across the United States. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials generally assess the effectivity of new does drugs. The role of the studies / undertakings is to solve specific human healthcare questions. Clinical trials are a popular way for doctors, government agencies, and private sector companies to find treatments for all kinds of conditions, including Local Flurbiprofen to Treat Pain Following Wisdom Tooth Extraction. Local Flurbiprofen to Treat Pain Following Wisdom Tooth Extraction Clinical Trials and other clinical trials allow for volunteers to access health treatment choices before they are available to the general public. Many times the test subjects get treatment for without cost, and sometimes they are compensated for their time. Occasionally there is a cost for a Local Flurbiprofen to Treat Pain Following Wisdom Tooth Extraction clinical trial. Test subjects typically receive the most effective healthcare possible for their Local Flurbiprofen to Treat Pain Following Wisdom Tooth Extraction condition. Risks are a reality, nonetheless, and could include extra or frequent dr. calls, health hazards (perhaps life-jeopardizing), and/or the treatment being ineffective. Trials are federally regulated with rigid guidelines to protect clinical trials subjects.

Local Flurbiprofen to Treat Pain Following Wisdom Tooth Extraction
For Condition: Pain
Status: Completed
Sponsor(s): National Institute of Dental and Craniofacial Research (NIDCR) ,
Synopsis: This study will evaluate the effectiveness of the non-steroidal anti-inflammatory drug flurbiprofen (Ansaid® (Registered Trademark)) in relieving pain following oral surgery. Flurbiprofen is approved by the Food and Drug Administration for treatment of arthritis pain. Patients 16 years of age and older requiring third molar (wisdom tooth) extraction may be eligible for this study. Patients will undergo oral surgery to remove two lower third molar teeth. Before surgery, they will be given a local anesthetic (lidocaine with epinephrine) injected in the mouth and a sedative (Versed) infused through a catheter (thin plastic tube) placed in an arm vein. At the time of surgery, patients will also be given flurbiprofen or a placebo formulation (look-alike substance with no active ingredient) directly into the extraction site and a capsule that also may contain flurbiprofen or placebo. One in seven patients will receive only placebo. All patients will fill out pain questionnaires and stay in the clinic for up to 6 hours for observation of bleeding and medication side effects. Patients who do not have satisfactory pain relief from the test medicine after surgery may request a standard pain reliever. A small blood sample will be collected during surgery and at 15 minutes, one-half hour and 1, 2, 3, 4, 5, 6, 24 and 48 hours after surgery to measure flurbiprofen blood levels. A total of 33 ml (about 2 tablespoons) of blood will be drawn for these tests. Samples collected on the day of surgery will be drawn from the catheter used to administer the sedative; the 24- and 48-hour samples will be taken by needle from an arm or hand vein. Urine samples will also be collected between 4 and 6 hours after surgery and again at 24 and 48 hours after surgery.
Details: This study proposes to evaluate the analgesic efficacy, tissue response, and adverse effects of microencapsulated preparations of a nonsteroidal anti-inflammatory drug (NSAID) and a long-acting local anesthetic administered into post-extraction sites prior to pain onset. Subjects (N=84) will have two mandibular impacted third molars removed and be randomly allocated to receive one of six possible treatments placed into the sockets: 0 mg (placebo formulation), 3.125 mg, 6.25 mg, 12.5 mg, or 25 mg flurbiprofen, or 50 mg bupivacaine. Each patient in these six groups (N=12/group) will also receive an oral placebo capsule. The seventh group of subjects will receive a placebo at the extraction sites and 25 mg of flurbiprofen orally. Subjects will remain at the clinic for six hours following drug administration to record every 30 minutes the offset of mandibular anesthesia, postoperative pain intensity, side effects, and for observation of recurrent bleeding. Demonstration of a dose-responsive relationship for flurbiprofen at doses lower than needed for analgesia following oral administration will provide the basis for a second study in which an optimal dose of flurbiprofen will be combined with bupivacaine.
Eligibility:
Study Type: Interventional, Treatment, Safety/Efficacy
Minimum Age/Maximum Age: /
Genders: Both
Protocol Entry Criteria: Patients of either sex requiring removal of two impacted mandibular third molars (partial bony or soft tissue impaction). 16 years of age of older. Indicates willingness to undergo oral surgery with local anesthesia and intravenous midazolam only. Willing to return for the removal of the remaining maxillary third molars at a second appointment. Patients with a history of allergy to flurbiprofen, aspirin, or any NSAID will be excluded. Those with a history of aspirin or NSAID-induced asthma will be excluded. Females of childbearing potential who are not practicing adequate contraception will be excluded. Pregnant or nursing females will be excluded. Patients with recent history or present signs of renal, hepatic, endocrine, pulmonary, cardiac, gastrointestinal, neurologic, or cerebral function impairment will be excluded. Those with psychiatric disorders will be excluded. Patients who have taken an investigational drug within 30 days of this study will be excluded. Those who have taken another analgesic, steroid, opioid, or NSAID within 24 hours prior to the study will be excluded. Those with an absence of bilateral local anesthesia during surgery as evidenced by anesthesia or paresthesia of the lower lip postoperatively will be excluded. Patients who use drugs which will interact with NSAID such as aspirin, warfarin, probenecid, methotrexate, lithium and diuretics will be excluded.
