Summary

The purpose of this study is to evaluate the efficacy and safety of multiple doses of Ibuprofen 600 mg Extended-Release Tablets in a study of dental pain following extraction of third molar teeth.

Eligibility Criteria

Inclusion Criteria

  • Males and females 16 to 45 years of age;
  • Outpatients scheduled to undergo surgical extraction of 1-2 impacted third molar(s), one of which must be a mandibular impaction that is partially impacted in either tissue or bone;
  • At least a score of 5 on the 11-point pain intensity numerical rating scale (PI-NRS) at baseline;
  • Use of only the following preoperative medication(s) / anesthetic(s): short-acting local anesthetic (e.g., mepivacaine or lidocaine) with or without vasoconstrictor and/or nitrous oxide;
  • Reliable, cooperative, and adequate intelligence to record the requested information on the analgesic questionnaire form;
  • Subjects (or the parent or legal guardian of subjects under the age of 18 years) are required to read, comprehend, and sign the informed consent. Subjects requiring a parent or legal guardian to sign the informed consent will be required to sign an assent;
  • Examined by the attending dentist or physician and medically cleared to participate in the study; and,
  • In general good health and have no contraindications to any of the study meds.

Exclusion Criteria

  • Presence of a serious medical condition (e.g., poorly controlled hypertension, poorly controlled diabetes, significantly impaired cardiac, renal or hepatic function, hyper- or hypothyroidism);
  • Use of a prescription or nonprescription drug with which the administration of ibuprofen, celecoxib, any other non-steroidal anti-inflammatory drug (NSAID), or acetaminophen, is contraindicated;
  • Acute local infection at the time of surgery that could confound the post-surgical evaluation;
  • Females who are pregnant, lactating, of child-bearing potential, or postmenopausal for less than 2 years and not using a medically approved method of contraception (i.e., oral, transdermal, or implanted contraceptives, intrauterine device, diaphragm, condom, abstinence, or surgical sterility), or females who test positive on a urine-based pregnancy test;

  • Habituation to analgesic drugs (i.e., routine use of oral analgesics 5 or more times per week);
  • History of allergic reaction (eg, asthma, rhinitis, swelling, shock, or hives) to ibuprofen, naproxen, aspirin, celecoxib, any other NSAID, or acetaminophen;
  • Prior use of any type of analgesic or NSAID 5 half-lives of that drug or less before taking the first dose of study medication, except for pre-anesthetic medication and anesthesia for the procedure;
  • Ingestion of any caffeine-containing beverages, chocolate, or alcohol 4 hours or less before taking the first dose of study medication;
  • Has taken an investigational product within the past 30 days;
