The Sunnybrook Health Sciences Acute Pain Service (APS) does not know if 200 mg of Gabapentin is effective at reducing morphine consumption, and improving analgesia. Much higher doses (i.e. greater than 1800 mg/day) published in the literature were initially used at Sunnybrook, but many patients (anecdotally) became too sedated. We are currently using the dose suggested in our protocol 200 mg TID without any major problems. Therefore our goal is to assess if Gabapentin 200 mg does in fact have opioid reducing and analgesic benefits in the radical prostate population. Our pilot data from 15 patients indicates these benefits might exist. Furthermore, examining the role of gabapentin in regards to perioperative anxiety and following patients beyond the acute post surgical time period and following any changes related to their functional recovery and quality of life will help to close some of the gaps in the literature regarding the perioperative usefulness of gabapentin.
