Active clinical trials for "Gastroesophageal Reflux"

The results on the efficacy of the formulations based on alginic acid are controversial. Corvaglia et al demonstrated a significant reduction in reflux episodes in preterm infants by evaluation with pH-impedance analysis. This study concludes that the use of alginic acid reduces the acidity of the gastroesophageal reflux (GER) and has a non-systemic effect and a lesser presence of side effects compared to the use of H2-receptor antagonist(H2RA) and proton pump inhibitor (PPI).

GERD is due to gastric content reflux to esophagus cause symptom and complication including intra-esophagus such as reflux esophagitis, and extra-esophagus such as cough etc. Because the changes of dietary habit, and improvement of examination skill and data analysis, the prevalence of GERD increased 2.5 multiple from 1995 to 2002, and suggesting the prevalence is 25% in Taiwan community. Although proton pump inhibitor (PPI) can inhibit gastric acid secretion, relief symptom and enhancing repair of esophageal damage, therefore, PPI is a main drug for the treatment of GRED, but because of PPI has disadvantage of poor compliance, and slow gastric empty time and hypersensitivity, and about 40-50% of GERD patients is inefficacy. In addition, PPI produces bone fracture, community pneumonia and diarrhea in patient with long-term use. Wu-Chu-Yu tang consists of Evodia fargesii Dode (Evodia Fruit), Panax ginseng C. (Ginseng), Ziziphus jujube Mill (Chinses Date), Zingiber officinale Rosee (Fresh Ginger). According to "I-Fang-Chi-Chieh" and "Shanghonzobinglun" recordings that Wu-Chu-Yu tang can treat vomiting, and also can relax gastric tonicity and can enhance peristalsis of stomach. Therefore, the purpose of the present study was to investigate the efficacy of Wu-Chu-Yu tang on GRED, and this effect of Wu-Chu-Yu tang compared to PPI Omeprazole.

The purpose of this study is to find out if people who have non-erosive reflux disease (NERD) have changes the investigators can see with a microscope (called confocal endomicroscopy) that is used during endoscopy (a camera scope evaluation of the inside of your stomach and swallowing tube). Traditionally the investigators have used trials of acid blocking medications (PPIs), endoscopy and measurements of acid in the swallowing tube (the esophagus) to determine if the investigators think acid is causing troublesome symptoms. The medical community believes that these symptoms are due to increased spaces between the cells that make up the swallowing tube. The investigators can directly see those spaces with a new microscope that the investigators can pass through the camera scope. Participants will be assigned to take one of two medications omeprazole and sucralfate (both approved medications for stomach symptoms) to treat their symptoms and record how well the treatment works. The investigators then will look to see if the microscope can predict which medication will work best for patients in the future. The investigators also plan to measure the acid levels in your swallowing tube and do a camera evaluation of your swallowing tube and stomach as this is standard for patients with your symptoms. The investigators will compare the results of those studies to the microscope findings.

Cough is the most common complaint for which patients seek medical attention in the United States, accounting for approximately 1 billion dollars in health care expenses annually. Gastroesophageal reflux disease (GERD) is the sole cause of chronic cough in up to 20-40% of all cases. The majority of these patients with GERD-induced cough have no classic "heartburn" symptoms, so this important cause of cough can thus be difficult to detect. Our hypothesis is that changes in exhaled breath condensate (EBC) pH can be used as a sensitive and non-invasive marker to identify subjects with cough caused by acid reflux.

There are no clear conclusive clinical reports defining the adequate effective dose of midazolam in patients undergoing day-case esophageal-gastro-duodenoscopy (EGD). Defining such dosage will facilitate practitioners who are not anesthesia professionals to administer sedative drugs to establish a satisfactory level of moderate sedation. Our first aim is to determine the effective dose for 90% of patients (ED 90) of midazolam undergoing day-case EGD.

The dual antiplatelet therapy based on aspirin plays an important role in the treatment of patients with coronary heart disease. Although aspirin is widely used and effective, it has many limitations in the long-term including increased risk of bleeding. In patients with coronary heart disease and gastroesophageal reflux disease, the symptoms of gastroesophageal reflux are usually aggravated after the application of aspirin. As an antiplatelet drug, indobufen can reversibly and selectively inhibit platelet cyclooxygenase-1 (COX-1), thereby blocking the synthesis of thromboxane B2 (TXB2) and exerting its antiplatelet effect, and it does not affect the production of prostaglandins and endothelial prostacyclins in gastrointestinal mucosa. It has less gastrointestinal injury and lower risk of bleeding. This project is to study the effects of indobufen or aspirin on gastric acid secretion and gastroesophageal reflux in patients with coronary heart disease and gastroesophageal reflux disease treated with dual antiplatelet therapy.

The aim of the study is to assess the effectiveness of this new formula on regurgitations and secondarily its effect on digestive tolerance through a randomized, controlled, double-blind trial against a comparator.

Gastroesophageal reflux disease (GERD) is a common ailment affecting a significant portion of the US population. With the advent and increased use of esophageal impedance monitoring, both acid and nonacid reflux disease can be better diagnosed and treated. Patients with severe symptoms or symptoms refractory to medical management may be offered anti-reflux surgery for optimal treatment. Though there are a handful of studies evaluating the efficacy of anti-reflux surgery on those patients with acid or non-acid related reflux disease, the comparison between acid and non-acid reflux disease following surgery is lacking. We propose a prospective study comparing clinical outcomes from those patients with acid versus non-acid reflux disease following anti-reflux surgery with the use of validated and disease specific quality of life surveys.

To compare the complete healing of erosive esophagitis(EE) after 3 weeks of treatment with Secretol 80/80 versus Nexium 40 mg daily.

The purpose of this study is to evaluate the safety of rabeprazole 20mg/day in polymedicated patients and to examine the necessity of adjusted dosage in both therapies (rabeprazole and concomitant drug). Proton pump inhibitors (PPI) act in the final step of the gastric secretion. PPI's block ATP-ase H+/K+ in gastric parietals cells. It has been described that inhibition of acid secretion has produced the recovery of the gastroesophageal pathology in a high percentage of the patients resistant to conventional drugs. In this context, the objective of the study is to evaluate the safety of rabeprazole as a concomitant treatment and examine the clinical practice the interaction with drugs whose absorption has gastric pH dependence.
