During osteoporosis therapy with alendronate, esophagitis and stomach ulceration may occur, requiring the concurrent use of drugs which decrease gastric juice production. The aim of the present study was to investigate the effect of concurrent administration of proton pump (H+/K+ATP-ase) inhibitors: omeprazole or pantoprazole and alendronate on bone remodeling in ovariectomized rats. The experi...

OBJECTIVES Cysteamine prevents organ damage in children with cystinosis, but may cause gastrointestinal (GI) symptoms. In this study we evaluated the nature of GI disease, and the value of omeprazole in controlling GI symptoms in these children. STUDY DESIGN Upper GI disease was evaluated with endoscopy, gastrin levels, and acid secretion studies after oral administration of cysteamine, befor...

Twenty four hour intragastric acidity was measured in five duodenal ulcer patients studied at least three times. The effects of different dosage regimens of intravenous omeprazole was compared with placebo. Mean intragastric acidity from 1000 to 0800 was 34.3 +/- 4.3 mmol/l on placebo. After omeprazole 80 mg at 0900 and 40 mg at 1700 mean acidity was 2.1 +/- 0.9 mmol/l and after omeprazole 80 m...

BACKGROUND Upper gastrointestinal bleeding is the severe complication of stress-related mucosal disease in hospitalized patients. In intensive care units (ICU), risk factors are well defined and only mechanical ventilation and coagulopathy proved to be relevant for significant bleeding. On the contrary, in non-ICU settings there is no consensus about this issue. Nevertheless, omeprazole is stil...

BACKGROUND Chronic proton pump inhibitor administration has been associated with electrolyte and cobalamin deficiency, disrupted bone homeostasis, hypergastrinemia, and rebound acid hypersecretion in humans. It is unknown if this occurs in cats. OBJECTIVES Prolonged oral omeprazole results in altered bone mineral density or content, serum calcium, magnesium, cobalamin, and gastrin concentrati...

The efficacy of omeprazole 20 mg a day was assessed against ranitidine 150 mg twice a day in the healing and relapse of duodenal ulcer. Forty three endoscopically verified cases were allocated to 2 weeks of treatment, which was extended to 4 weeks, if the ulcer persisted on day 15. Two cases were excluded due to deviation from the protocol. Of 41 evaluable cases, 21 received omeprazole and 20 r...

We conducted a six week double blind randomised study of 176 patients with prepyloric gastric ulcer to determine whether the proton pump inhibitor, omeprazole 30 mg daily would accelerate healing and pain relief, as compared with cimetidine 1 g daily. At two, four, and six weeks after entry ulcers healed in a larger percentage of patients treated with omeprazole (54, 81, and 86%) than of those ...

The economic evaluation of new medicines is increasingly important for pricing, registration and selection for use. A decision-analytic strategy was performed to assess the economic impact of antacids alone (phase I therapy), and in combination with either omeprazole, 20 mg once daily, or ranitidine, 150 mg twice daily, for patients with persistent, symptomatic gastro-oesophageal reflux disease...

Eleven adult patients with nocturnal asthma, and gastro-oesophageal reflux documented by endoscopy or ambulatory oesophageal pH monitoring completed a double-blind cross-over study (4 week treatment, one week run-in and cross-over periods) comparing the effects of omeprazole 20 mg daily and placebo on asthma control assessed by symptoms, peak expiratory flow rate and bronchodilator usage. Omepr...
