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.

Conditions

Acute Pain

Keywords

Primary, unilateral, first metatarsal bunionectomy with osteotomy

Outcome Measures

Primary Outcomes (1)

• Total Patient Controlled Analgesic (PCA) Hydromorphone Consumption Over the 24 Hours Post-surgery

  Total dose (amount) of hydromorphone via patient controlled analgesic (PCA) pump required in the 24 hours post-surgery in each of the treatment arms: placebo, pregabalin 300 mg or naproxen 550 mg.

  First 24 hours following surgery

Secondary Outcomes (1)

• Time to First Request of PCA Hydromorphone

  First 24 hours following surgery

Study Arms (3)

Arm 1: Pregabalin 300 mg

ACTIVE COMPARATOR

Drug: pregabalin

Arm 2: naproxen sodium 550 mg

ACTIVE COMPARATOR

Drug: naproxen sodium

Arm 3: Placebo

PLACEBO COMPARATOR

Drug: Comparator: Placebo

Interventions

pregabalin DRUG

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.

Arm 1: Pregabalin 300 mg

naproxen sodium DRUG

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.

Also known as: naproxen

Arm 2: naproxen sodium 550 mg

Comparator: Placebo DRUG

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.

Arm 3: Placebo
