The Effect of Perioperative Pregabalin on the Incidence of Chronic Post-thoracotomy Pain Syndrome
A Multicenter Prospective Randomized Double-blind Placebo Controlled Trial Assessing the Effect of Perioperative Pregabalin on the Incidence of Chronic Post Thoracotomy Pain Syndrome

Pregabalin, administered prior to and following lateral thoracotomy surgery will reduce the likelihood of chronic post-thoracotomy pain syndrome (CPTPS).

A total of 200 patients scheduled for lateral thoracotomy will be randomly assigned to receive either placebo or 150 mg pregabalin (Lyrica)1 hour prior to surgery, 12 hr after surgery and then every 12 hr for an additional 10 days. While in the hospital, patients will be assessed for pain intensity, satisfaction and side effects. Patients will be re-assessed at 2, 4 and 6 months following surgery.
Interventional
Phase 3
Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Chronic Pain
Drug: Pregabalin
pregabalin capsules (150mg,oral) will be administered 1 hour before lateral thoracotomy, 12 hours after the thoracotomy and then 12 h BID for 10 additional days.
Other Names:
  • Pregabalin
  • Lyrica
  • Placebo Comparator: Placebo capsules
    one placebo capsule will be administered 1 hour before lateral thoracotomy, 12 hours following the thoracotomy and then every 12h BID for 10 days following lateral thoracotomy.
    Intervention: Drug: Pregabalin
  • Active Comparator: pregabalin capsules
    Pregabalin capsules (150mg) will be administered one hour before lateral thoracotomy, 12 hours following the thoracotomy and then every 12 hours (BID) for 10 days following lateral thoracotomy.
    Intervention: Drug: Pregabalin
