OTC NCT00443963 Total Antioxidant Effects of Esomeprazole in Dyspeptic Patients Receiving Non-Steroidal Anti-Inflammatory Drugs Terminated AstraZeneca Phase 4 2006-12-01 We hypothesize that patients receiving NSAID drugs with dyspeptic symptoms have increased production of gastric levels of free radicals. The primary objective of the study is to determine if Esomeprazole Magnesium increases gastric total antioxidant capacity and decreases gastric free radical production in humans. Patients (age 18 years and older) with no history of upper GI bleeding who are receiving non-steroidal anti-inflammatory drugs and then develop dyspepsia will be recruited from our primary care clinic in Washington, DC. All eligible individuals will undergo biopsies of antrum and corpus. The subjects will be randomized to receive either Zantac OTC or Nexium for 15 days. On day 15, all patients will undergo repeat upper endoscopy to obtain biopsies of antrum and corpus. Tissue samples will then be extracted to determine total antioxidant capacity and lipid peroxide levels (as an indirect marker of free radical production).

OTC NCT03145012 Histamine Receptor 2 Antagonists as Enhancers of Anti-Tumour Immunity Not yet recruiting Dalhousie University Phase 4 2018-03-01 The immune response against tumors can be highly effective in preventing tumor development, growth and metastasis under certain circumstances. However, tumor associated immune suppression can profoundly limit the impact of natural tumor immunity and also reduce the effectiveness of tumor immunotherapy strategies. A major component of tumor associated immune suppression is mediated by myeloid cells, especially the monocytic subset of myeloid derived suppressor cells (MDSC). In recent studies that were conducted through a CCSRI Innovation grant, the investigators discovered that oral treatment of mice with the commonly used histamine receptor 2 (H2) antagonists ranitidine or famotidine inhibits both primary breast tumor development and metastasis, in three distinct mouse tumor models and reduces the numbers of monocytic MDSC. These findings have enormous potential to aid in effective cancer immunotherapy and may have immediate implications for cancer patients. The objective of this investigation is to determine whether treatment with the H2 receptor antagonist ranitidine alters immune suppression, through modulation of immune cell populations. The investigators will examine peripheral blood monocyte, neutrophil and NK cell numbers, subsets and activation status from healthy volunteers treated for 6 weeks with daily oral ranitidine. Ranitidine is widely available and used over the counter in Canada. These drugs are widely recognized as safe, well tolerated and have very few side effects. It has been suggested that among the general population, over 10% of those over the age of 65 take such medications on a regular basis for relief against gastrointestinal discomfort. The outcome of pre-clinical studies in mice warrant further investigation into transferability to humans. If the outcome of the current proposal proves to be viable, then these drugs could provide a safe method to reduce tumor associated immunosuppression with broad implications, both for current cancer patients and for those at high risk of developing cancer. Further to this, the outcome of our proposal may provide a new strategy for improving the effectiveness of T-cell mediated immunotherapy.

OTC NCT04397445 Clinical Study to Investigate the Urinary Excretion of N-nitrosodimethylamine (NDMA) After Ranitidine Administration Not yet recruiting Spaulding Clinical Research LLC Phase 1 2020-06-01 Ranitidine is an over-the-counter and prescription drug, which decreases the amount of acid secreted by the stomach. Some ranitidine medicines contain an impurity called N-nitrosodimethylamine (NDMA) at low levels. NDMA is classified as a probable human carcinogen (a substance that could cause cancer) based on results from laboratory tests. NDMA is a known environmental contaminant and found in water and foods, including meats, dairy products, and vegetables. The US Food and Drug Administration (FDA) has found levels of NDMA in some ranitidine products similar to the levels you would expect to be exposed to if you ate common foods like grilled or smoked meats. The ranitidine that will be used in this study has been tested twice (months apart) and shown to have stable NDMA levels well below the acceptable daily limit. Of note, the risk of NDMA with ranitidine is only relevant with prolonged chronic administration as at the acceptable limit, there is approximately a 1 in 100,000 chance of cancer after 70 years of exposure to that level. FDA has also conducted tests that simulate the potential formation of NDMA from ranitidine after it has been exposed to acid in the stomach with a normal diet. Results of these tests indicate that NDMA is not formed in typical stomach conditions. Similarly, if ranitidine is exposed to a simulated small intestinal fluid, NDMA is not formed. Other laboratory experiments suggest a combination of nitrites, such as found in processed meats, and an acidic environment may increase NDMA formation, however the levels of nitrites tested were very high. Separately, a previous study in 10 healthy volunteers showed that volunteers who received ranitidine had an increase in urinary NDMA excreted over 24 h. The level of increase was greater than would be expected from laboratory testing. This clinical study is being performed to determine if and how much NDMA is produced from ranitidine in the human body and whether nitrite-containing foods may increase formation of NDMA. The study will use a prescription dose of ranitidine (300 mg) to test whether there is increased urinary NDMA excretion levels over 24-hours after ranitidine administration in comparison to placebo when participants are administered low nitrite/NDMA meals and when subjects are administered high nitrite/NDMA meals. On 4 different days, each participant will receive ranitidine or placebo with high nitrite/NDMA meals and ranitidine or placebo with low nitrite/NDMA meals.

All Clinical Trials for Ranitidine

Trial ID Title Status Sponsor Phase Start Date Summary
NCT00000964 The Effect of Stomach Acid on Foscarnet Completed National Institute of Allergy and Infectious Diseases (NIAID) Phase 1 1969-12-31 To see if ranitidine, by reducing stomach acidity, can enhance the effectiveness of foscarnet, by making foscarnet more available to the body. Foscarnet is an antiviral compound. Laboratory studies have shown it to be active against HIV. However, only 12 - 22 percent of an oral foscarnet dose is absorbed by the body. Ranitidine suppresses gastric acid output, increasing gastric pH. Thus by increasing gastric pH (decreasing stomach acidity), less foscarnet is expected to be decomposed or broken down in the stomach. Thus, more foscarnet should be absorbed into the body.
NCT00002106 A Pilot Randomized, Double-Blind, Placebo-Controlled, Parallel Design, Multicenter Trial to Evaluate the Effect of Ranitidine on Immunologic Indicators in Asymptomatic HIV-1 Infected Subjects With a CD4 Cell Count Between 400-700 Cells/mm3 Completed Glaxo Wellcome Phase 2 1969-12-31 To evaluate the effect of ranitidine on immunologic indicators in asymptomatic HIV-1 infected patients with CD4 counts of 400-700 cells/mm3.
NCT00037570 Study Evaluating Pantoprazole in Peptic Ulcer Hemorrhage Completed Wyeth is now a wholly owned subsidiary of Pfizer Phase 2 2000-11-01 This is a multicenter, randomized, double-blind, parallel-group, dose-ranging, comparator-controlled study of the effect of pantoprazole on intragastric pH after successful endoscopic hemostasis in hospitalized patients. Patients will receive either intravenous pantoprazole (one of two regimens) or ranitidine (the comparator) within 2 hours of successful hemostasis and administration will continue for 72 hours after hemostasis.
NCT00146549 Trastuzumab in Combination With Vinorelbine or Taxane-Based Chemotherapy in Patients With Metastatic Breast Cancer Completed Brigham and Women's Hospital Phase 3 2001-08-01 The purpose of this study is to compare two different combinations of chemotherapy with trastuzumab as initial treatment for HER2 positive advanced breast cancer. Half of the patients will receive trastuzumab in combination with a taxane form of chemotherapy (either paclitaxel or docetaxel), while the other group will receive trastuzumab in combination with vinorelbine.
