Brief 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.

Detailed Description

This is a single-center, multiple-dose, randomized, placebo-controlled, double-blinded, parallel group trial 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. The surgery will consist of surgical extraction of 1-2 impacted third molars, of which one must be a mandibular impaction that is partially impacted in either tissue or bone. Subjects will be stratified according to baseline pain intensity, as rated on an 11-point pain intensity numerical rating scale (PI-NRS)and gender.

Conditions

Pain; Post-Operative Pain; Third Molar Extraction

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: QUADRUPLE

Study Groups

Ibuprofen 600 mg ER group

One-hundred and sixty subjects will be randomly assigned to the Ibuprofen 600 mg ER treatment group based on gender and baseline pain intensity, as rated on an 11-point numerical rating scale (PI-NRS; 5-7 moderate pain, or 8-10, severe pain).

Group Type: EXPERIMENTAL

Ibuprofen 600 mg Extended-Release Tablets

Intervention Type: DRUG

Ibuprofen 600 mg Extended-Release Tablet: One 600 mg tablet taken orally every 12 hours or twice daily (BID). Each dose was administered with at least 6 ounces of water. Dose 1 was administered at hour 0, Dose 2 was administered at hour 12, Dose 3 was administered at hour 24 and Dose 4 was administered at hour 36.

Placebo group

Eighty subjects will be randomly assigned to the Placebo treatment group based on gender and baseline pain intensity, as rated on an 11-point numerical rating scale (PI-NRS; 5-7 moderate pain, or 8-10, severe pain).

Group Type: PLACEBO_COMPARATOR

Placebo

Intervention Type: DRUG

Placebo: One matching placebo tablet was taken orally every 12 hours or twice daily (BID). Each dose was administered with at least 6 ounces of water. Dose 1 was administered at hour 0, Dose 2 was administered at hour 12, Dose 3 was administered at hour 24 and Dose 4 was administered at hour 36.

• 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;

• 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;

• 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;
• Has previously been entered into this study; and,
