In a randomised, double blind, parallel group study in patients with symptomatic gastric ulcer (94% greater than or equal to 5 mm diameter), 102 received omeprazole 20 mg om and 87 cimetidine 400 mg bd. After four weeks 73% and 58% (p less than 0.05) respectively had healed (eight weeks: 84% and 75%, ns). After four weeks, a greater proportion (81%) of omeprazole treated patients was symptom free than of those receiving cimetidine (60%; p less than 0.01). Over the first two weeks, patients receiving omeprazole had less day pain, less night pain and took fewer antacids than those receiving cimetidine (all p less than 0.05). The difference between omeprazole and cimetidine was not appreciably affected by age, smoking, size of the ulcer and trial centre. Tolerability was similar in the two treatment groups. In the treatment of symptomatic gastric ulcer, omeprazole relieves the symptoms more quickly than cimetidine and heals a greater proportion of ulcers within four weeks.

This study presents the first set of data on the removal of proton pump inhibitors (PPIs) and histamine H2 receptor antagonists (HRAs) and their transformation products in two Romanian wastewater treatment plants (WWTPs), as well as the impact of these organic pollutants on freshwater receiving effluents. The research investigated eight target pharmaceuticals and three metabolites using a newly developed and validated Liquid Chromatography - Mass Spectrometry (LC-MS/MS) method. The combined determination had a range of quantification limits varying from 0.

Invasive fungal aspergillosis is a leading cause of morbidity and mortality in many species including avian species such as common ravens (). Methods were developed for mass spectral determination of voriconazole in raven plasma as a means of determining pharmacokinetics of this antifungal agent. Without further development, GC/MS/MS (gas chromatography-tandem quadrupole mass spectrometry) proved to be inferior to LC/MS/MS (liquid chromatography-tandem quadrupole mass spectrometry) for measurement of voriconazole levels in treated raven plasma owing to numerous heat-induced breakdown products despite protection of voriconazole functional groups with trimethylsilyl moieties.

Hydrochloric acid is crucial in gastric physiology. In 1978 cimetidine, the first H2 antagonist of histamine receptors on the gastric parietal cell was introduced into therapy, inducing acid. Lasting the years, several studies focused on the potential relationship between inducing hypo-achlorhydria and risk of developing gastric cancer.

The present network meta-analysis aimed to enhance the corresponding evidence with respect to the efficacy and safety of pharmaceuticals treatments. Frequentist network meta-analysis was used. Medical literature up to November 2022 was searched for randomized clinical trials assessing the efficacy and safety of these pharmaceuticals, either compared with each other or compared with placebo.

Gastric ulcer is associated with weakening of the mucous coating of the stomach and damages to the intestinal lining. It is caused by assisted by enzymes including VacA, which necessitates the need for inhibitors of VacA. Bioactive compounds from have been documented to have anti-inflammatory activities.
