Sixty patients with gastric ulcers were treated for four weeks with either 1 g cimetidine per day or with identical tablets containing lactose. The healing rate, assessed by endoscopy, was 23 out of 35 (66%) in the patients given cimetidine and 13 out of 25 (52%) in those given placebo. The difference between the groups is not significant. During each of the four weeks of the study the cimetidi...

The application of a linear algebraic method to the potentiometric titration of a mixture of tartaric and citric acids and sodium carbonate and sodium hydrogen carbonate (previously treated with strong acid), permits the determination of the concentration of each individual acid and the total equivalent of carbonate in antacids. It is also possible to determine individual concentrations of sodi...

The main objectives of tuberculosis therapy are to cure the patients and to minimize the possibility of transmission of the bacillus to healthy subjects. Adverse effects of antituberculosis drugs or drug interactions (among antituberculosis drugs or between antituberculosis drugs and other drugs) can make it necessary to modify or discontinue treatment. We describe the general mechanism of acti...

30 INTRODUCTION Gastroesophageal reflux disease (GERD) is defined as the occurrence of chronic symptoms or mucosal damage produced by the abnormal reflux of gastric contents into the esophagus. The most common symptom is heartburn, experienced by 10% of the United States population daily and by 40% at least once monthly (1). In addition, it is estimated that more than 40 million people use over...

Hypermagnesemia is an uncommon but a potentially serious clinical condition. Over-the-counter magnesium containing products are widely used as antacids or laxatives. Although generally well tolerated in patients with normal renal function, their unsupervised use in the elderly can result in severe symptomatic hypermagnesemia, especially in those patients with concomitant renal failure and bowel...

Dolutegravir is neither an inducer nor inhibitor of metabolising enzymes, and it therefore has a low propensity to act as perpetrator drug-drug interactions. Clinically significant decreases in dolutegravir exposure occur when co-administered with strong inducers (e.g. rifampicin, efavirenz) drug enzymes efflux transporters for which substrate – this can be overcome by increasing the dose from ...

OBJECTIVES To examine prescribing of non-steroidal anti-inflammatory drugs (NSAIDs) in general practice and to compare the results with a 1993 study. To assess numbers at risk of gastrointestinal adverse events using the National Institute for Clinical Excellence (NICE) guidance on the use of cyclo-oxygenase (Cox) II selective drugs. METHODS Patients currently prescribed a NSAID for 2 months ...
