Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study is being done to collect new information on irritable bowel syndrome, a disease that causes abdominal pain that does get better with treatment or keeps coming back ("chronic"). To better understand what causes the irritable bowel syndrome, we are studying drugs used to treat pain, dextromethorphan, naloxone, fentanyl, and lidocaine. We will study the effects these drugs have on experimental pain. Dextromethorphan is used in non-prescription cough syrups. Naloxone is used for reversing the effects of narcotic pain relievers. Fentanyl is a narcotic used to treat pain and to make a person relaxed (sedated) before anesthesia. The purpose of this study is to see what kinds of pain are affected by these drugs in persons who have irritable bowel syndrome and persons who do not have this problem.
