A Randomized Study of the Effects of Single-dose Gabapentin versus  Placebo on Postoperative Pain and Morphine Consumption after Mastectomy

A single dose of 1,200 mg oral gabapentin resulted in a substantial reduction in postoperative morphine consumption and movement-related pain after radical mastectomy, without significant side effects. These promising results should be validated in other acute pain models involving central neuronal sensitization.
