Conditions: Acute Pain
Keywords: Primary, unilateral, first metatarsal bunionectomy with osteotomy
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 100
Healthy volunteers: no

Brief summary:
We are interested in whether bunionectomy can be used as a model to study the treatment of acute pain. It has been used to study the effect of Non-Steroidal Anti-inflammatory (NSAIDS) medications (such as ibuprofen) and other pain relieving drugs. We are interested to know if this model is useful to study other drugs for the treatment of acute pain. The other drugs being tested in this study are pregabalin and naproxen sodium. These drugs are approved for use by the Food and Drug Administration (FDA). This study is designed to test whether these two drugs are effective in treating pain after a bunionectomy.

Detailed description:

Arms:
arm 1: None arm 2: None arm 3: None

Interventions: intervention 1: pregabalin intervention 2: naproxen sodium intervention 3: Comparator: Placebo
Intervention descriptions: intervention 1: Patients will be randomized just prior to surgery to 1 of 3 study treatments: pregabalin (300 mg) treatment will be administered approximately 1 hour prior to surgery. Postoperatively, pregabalin (150 mg) will be dosed starting at 8 hours following T=0 and every 8 hours until 40 hours following T=0. intervention 2: Patients will be randomized just prior to surgery to 1 of 3 study treatments: naproxen sodium (550 mg) treatment will be administered approximately 1 hour prior to surgery. Postoperatively, naproxen sodium will be dosed starting 12 hours following T=0 and every 12 hours until 36 hours following T=0. intervention 3: Patients will be randomized just prior to surgery to 1 of 3 study treatments: placebo treatment will be administered approximately 1 hour prior to surgery. Postoperatively, placebo will be dosed starting at 8 hours following T=0 and every 8 hours until 40 hours following T=0.
