Nowadays, chronic pain mainly as a result of iatrogenic nerve damage is generally considered as the most frequent complication after inguinal hernia surgery. The primary objective of this randomised double-blind placebo-controlled trial is to investigate whether pregabalin reduces pain in patients with chronic pain of neuropathic origin after herniorraphy.

Condition Intervention Phase
Chronic Pain Drug: pregabalin Drug: placebo Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Chronic Pain Management After Herniorraphy:Pregabalin vs Placebo. A Double-blinded Randomised Controlled Clinical Trial.
