The tolerability of omeprazole was compared to control agents in 68 clinical studies that enrolled a total of 4846 patients, of whom 3096 received omeprazole. The incidence of adverse experiences was independent of omeprazole dose administered, the age of the patients, and the disease treated (duodenal ulcer or endoscopically verified gastroesophageal reflux disease). The most common clinical adverse experiences were headache, diarrhea, abdominal pain, and nausea. The most common laboratory adverse experiences were elevated aspartate aminotransferase and elevated alanine aminotransferase. Omeprazole was well tolerated, and the incidence of clinical and laboratory adverse experiences was similar in patients receiving omeprazole, placebo, cimetidine, or ranitidine.

Omeprazole has been marketed in France since 1989, for the healing of peptic ulcers, erosive reflux esophagitis and the Zollinger Ellison syndrome. It is a proton pump inhibitor which inhibits the acid secretion in the stomach. In the majority of the clinical trials, omeprazole has been found to be well tolerated: headache, dizziness, skin rash, constipation have just been noted. Since September 1989, 143 adverse reactions have been reported to pharmacovigilance centres and Astra France: 37 neurological and psychiatric side effects, especially confusion in patients with hepatic diseases and/or advanced age; 35 cutaneous reactions, generally rash and urticaria; 22 hematological effects: leucopenia and agranulocytosis have been reported but the relation with omeprazole is very uncertain; 10 gastrointestinal effects, generally diarrhoea, nausea, vomiting and abdominal pain; 8 hepatic disorders, especially moderate elevation of aminotransferases. This study confirms the safety of this drug, during short treatment; the frequency of notified adverse effects is about 1/12 200 treatments of 4 weeks. The ministry of health, has decided, in november 1991, to inform the prescribers of this potential toxicity of omeprazole, particularly, of the risk of confusion, hepatotoxicity and leucopenia.

A total of 1,456 patients were available for the All Patients Treated analysis of two large, randomized, double-blind, multicenter, controlled studies (Acid Suppression Trial: Ranitidine versus Omeprazole for NSAID-Associated Ulcer Treatment [ASTRONAUT] and Omeprazole versus Misoprostol for NSAID-Induced Ulcer Management [OMNIUM]). These studies examined the efficacies of omeprazole, 20 and 40 mg once daily (both studies), ranitidine, 150 mg twice daily (ASTRONAUT), and misoprostol, 200 microg four times daily (OMNIUM), for the healing of gastric ulcer, duodenal ulcer, or erosions, and the relief of dyspeptic symptoms. At entry, patients were receiving, and continued to receive, nonsteroidal anti-inflammatory drugs (NSAIDs), and had a gastric or duodenal ulcer, and/or >10 erosions in the stomach or duodenum at initial endoscopy. Patients were randomized to blinded treatment for 4/8 weeks until treatment success, which was defined as the healing of ulcer(s), <5 erosions at any site, and not more than mild dyspeptic symptoms. The proportions of patients reaching treatment success by 8 weeks were 77% with both doses of omeprazole, 63% with ranitidine, and 71% with misoprostol. In patients who initially had a gastric ulcer, more ulcers were healed at 8 weeks with omeprazole, 20 (83%) and 40 mg once daily (82%), than with ranitidine (64%) or misoprostol (74%). In patients who initially had a duodenal ulcer, 93% were healed at 8 weeks with omeprazole, 20 mg once daily, compared with 88% for omeprazole, 40 mg once daily, 79% for ranitidine, and 79% for misoprostol. Erosions healed slightly faster at 4 weeks with misoprostol, compared with the other regimens, but by 8 weeks most patients had <5 erosions per gastroduodenal region in each treatment group. Diarrhea and abdominal pain were more common in patients taking misoprostol, as were adverse events leading to withdrawal. Patients with duodenal ulcer or erosions at entry and the presence of Helicobacter pylori were good prognostic factors for overall treatment success. Using a model that included only patients with ulcers, those with smaller ulcers also had a higher likelihood of achieving treatment success. Against the background of these new data, omeprazole is the treatment of choice for healing NSAID-associated ulcers, on the basis of its efficacy and tolerability, and the optimal dose appears to be 20 mg once daily.

Familial Mediterranean fever (FMF) is an inherited multisystem disease manifested by painful, febrile attacks affecting the chest, abdomen, joints, and skin. No simple studies confirm the presence of FMF, contributing to the difficulty in diagnosis. A 10-year-old boy initially presented with a diffuse rash and complaints of bilateral joint pain of the hips, knees, and ankles and pain of the right shoulder. The child responded to daily naproxen. One year later, he continued to complain of hip, knee, ankle, and bilateral wrist pain. He also reported mild to moderate recurrent abdominal discomfort. Omeprazole provided intermittent relief. The patient continued to experience episodes of joint and abdominal pain. Two and a half years after he first presented, FMF was considered. In the second case, a 51-year-old man presented to the emergency department with complaints of fever, cough, and abdominal and joint pain. Fever, joint pain, and swelling decreased during the next few days. The patient was maintained on colchicine, with complete resolution of joint pain complaints during the next few days. Colchicine, 1 to 2 mg per day taken continuously during flare and quiescent periods, is the treatment of choice for FMF. Colchicine reduced the severity and frequency of attacks and may also delay or prevent secondary amyloidosis.

Background. Functional dyspepsia is a common chronic disorder with non specific upper abdominal pain or discomfort. Different approaches with anti-secretory, spasmolytic, prokinetic and anti-inflammatory effects and most preferably reduction of visceral hypersensitivity seem logical. In this study, we compared the effectiveness of the four most drugs used for treatment of dyspepsia in children. Methods. 169 patients between 2 to 16 years old that 47.3% was male and 52.7% was female were enrolled in this clinical trial study by the diagnosis of functional dyspepsia. Then for each patient one of the drugs; Omeprazole, Famotidine, Ranitidine or Cimetidine was administered, for a period of 4 weeks. Patients were followed after 2 and 6 weeks from the beginning of the treatment. Results. The distribution of drugs between these patients were including; 21.9% with Cimetidine, 21.3% with Famotidine, 30.8% with Omeperazole and 26% with Ranitidine that the proportion of patients with all symptoms relief were: 21.6% for Cimetidine, 44.4% for Famotidine, 53.8% for Omeprazole and 43.2% for Cimetidine (P = .024). In followups within 2 and 6 weeks after beginning medical therapy, no side effects due to drugs were seen. Conclusion. If a cure is defined as all symptoms relief after a period of 4 weeks treatment, our findings showed that Omeperazole are superior to Ranitidine, Famotidine, and Cimetidine for management of functional dyspepsia.

Here we aimed to evaluate the effectiveness of esomeprazole treatment strategies comparing with other proton pump inhibitors (PPI) in clinical practice for six months in the management of patients with symptomatic gastroesophageal reflux disease (GERD). An extensive search of the literature focusing on PPI therapeutic evaluation was performed up to December 2014. Risk ratio (RR) with its corresponding 95% confidence intervals (CIs) in each study was chosen as the effect size. Cochrane's Q statistic and I2 test were both conducted to evaluate heterogeneity across individual studies. Meta-regression was conducted to explore the source of heterogeneity and sensitive analysis was performed to assess the risk bias for the meta-analysis. Totally, eleven trials with high quality enrolled in the meta-analysis. Esomeprazole therapy (20 mg daily) had lower relapse rates than other drugs during six months maintenance treatment (RR = 0.67; 95% CI: 0.55-0.83). Heartburn (RR = 0.72; 95% CI: 0.57-0.92) and epigastric pain (RR = 0.82, 95% Cl: 0.70-0.96) were less likely to happen after esomeprazole treatment, and no significant advantage was found on acid regurgitation and dysphagia. Moreover, lower risk for serious adverse events was observed after esomeprazole therapy (RR = 1.40, 95% CI: 1.04-1.88). Blind method or difference controlled drugs did not influence heterogeneity across studies. Moreover, the conclusion on acid regurgitation, abdominal pain and dysphagia might be unstable. In GERD patients, esomeprazole 20 mg daily is more effective than other PPIs regarding relapse rates, symptoms of epigastric pain and heartburn, and serious adverse events.

Sphincter of Oddi dysfunction is caused by stenosis or dyskinesia of the sphincter of Oddi, leading to blockage of bile drainage from the common bile duct. We present the case of a 16-year-old female with chronic abdominal pain who underwent laparoscopic cholecystectomy for cholelithiasis but continued to experience abdominal pain, nausea, and vomiting along with persistently elevated ALT and AST levels. Postoperative abdominal ultrasound was nondiagnostic. Esophagogastroduodenoscopy showed mild reflux esophagitis and mild chronic Helicobacter pylori-negative gastritis. Omeprazole was started, but it did not decrease the frequency and severity of the abdominal symptoms. Magnetic resonance cholangiopancreatography did not reveal any pathology. Endoscopic retrograde cholangiopancreatography with manometry confirmed an elevated biliary sphincter pressure. Biliary sphincterotomy was performed, and the symptoms improved.
