This increased level of gastric acid is what causes the symptoms of the disease. Certain types of medication can control the secretion of gastric acid. In this study there are details on how drugs known as antihistamines (H2 receptor antagonists) can control the levels of gastric acid secretion.\n\nThe study describes; which patients are candidates for this research, what to do prior to initiating treatment, and the appropriate dose of antihistamine to be given.\n\nInitial doses of the medication will be given intravenously (injected through a vein) and later doses will be administered orally (by mouth).\n\nBy following the procedure, researchers will be able to determine if there is a more effective route of drug administration, as well as the effectiveness of antihistamines in patients treated surgically for Zollinger-Ellison pancreatic tumors with mildly elevated gastric acid levels.", "detailedDescription"=>"This protocol describes the use of histamine H2-receptor antagonists to control gastric acid hypersecretion in patients with Zollinger-Ellison syndrome. It details which patients will be considered for treatment with these agents, the pretreatment procedures and the procedures to be followed in establishing the proper intravenous dose of histamine H2-receptor antagonist. It also details the procedure to be used to establish a safe and effective oral long-term maintenance dose of either cimetidine, ranitidine, nizatidine, or famotidine. By following these procedures it will be possible to evaluate the effectiveness of intravenous histamine H2 therapy if it is determined this is important for antisecretory control during periods when patients cannot take oral gastric antisecretory agents. It will also be possible to evaluate the effectiveness of histamine H2-receptor in patients with Zollinger-Ellison syndrome after successful gastrinoma resection who continue to have mild gastric hypersecretion."}, "eligibilityModule"=>{"sex"=>"ALL", "stdAges"=>["ADULT", "OLDER_ADULT"], "minimumAge"=>"18 years", "healthyVolunteers"=>false, "eligibilityCriteria"=>"* INCLUSION CRITERIA:\n\nBasal gastric acid secretion of greater than 15 mEq/hr (normal less than 10) or greater than 5 mEq/hr if they have had a previous gastric resection, a fasting plasma concentration of immunoreactive gastrin of greater than 100 pg/ml (normal less than 100), a positive secretin provocative tests or histological diagnosis of gastrinoma."}, "identificationModule"=>{"nctId"=>"NCT00001241", "briefTitle"=>"Treatment of Zollinger-Ellison Syndrome", "organization"=>{"class"=>"NIH", "fullName"=>"National Institutes of Health Clinical Center (CC)"}, "officialTitle"=>"Medical Therapy of Zollinger-Ellison Syndrome", "orgStudyIdInfo"=>{"id"=>"890015"}, "secondaryIdInfos"=>[{"id"=>"89-DK-0015"}]}, "contactsLocationsModule"=>{"locations"=>[{"zip"=>"20892", "city"=>"Bethesda", "state"=>"Maryland", "country"=>"United States", "facility"=>"National Institutes of Health Clinical Center, 9000 Rockville Pike", "geoPoint"=>{"lat"=>38.98067, "lon"=>-77.10026}}]}, "sponsorCollaboratorsModule"=>{"leadSponsor"=>{"name"=>"National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK)", "class"=>"NIH"}}}}
