In an endoscopic controlled trial the effectiveness of pirenzepine in preventing stress ulcer in high risk patients for surgical operation was studied. 40 patients of both sexes aged between 19-72 were at random distributed to pirenzepine treatment (10 mg e.v./8 hours, starting the day before surgery to 10th day after it), or to "void" period (without specific therapy). Endoscopic findings was performed before and after treatment and every patient was daily monitored for: dyspepsia, defecation, residual intragastric volume, intestinal peristalsis, beginning oral food intake, haemodynamic and metabolic parameters. The results obtained showed the gastric and duodenal cyto-protective effect and the better post-operative clinical course, when pirenzepine was administered by parenteral infusion.

Antacids have for long been regarded as the mainstay of pharmacologic therapy in patients with dyspepsia. The advent of the histamine H2-antagonist and of proton pump inhibitors has provided simpler and overall more efficient therapeutic modalities for severe forms of dyspepsia. This relates especially to aggressive forms of peptic ulcer disease and severe reflux oesophagitis, where even high dose histamine H2-antagonist therapy has its clear limitations. Antacids nevertheless continue to be widely used in less severe forms of dyspepsia, especially in patients suffering from heartburn. In such patients self medication of antacids as first therapeutic measure is still very common. This is well exemplified by an American nd British survey. Out of 6760 randomly selected British general practice patients 875 suffered from reflux-like symptomatology without having consulted their physician for the symptomatology for minimum one year. Antacids were taken by 61% of them. The advent of controlled endoscopic trials and the emergence of the H2-receptor blockers as a yardstick of ulcer therapy, however, facilitated reappraisal of the value of antacids in various conditions. This has given a clear-cut answer in well defined entities such as peptic ulcer disease and stress ulcer prophylaxis but has left many open questions in heterogeneous conditions especially in and around gastroesophageal reflux disease.

Sucralfate is a cytoprotective drug widely used in clinical practice to prevent or treat several gastrointestinal diseases such as gastro-esophageal reflux, gastritis, peptic ulcer, stress ulcer and dyspepsia. Sucralfate is a safe and well tolerated drug, as demonstrated by the quite complete lack of side effects and it is, for this reason, one of the most important therapeutic choices in the management of acid related diseases during pregnancy. Moreover, sucralfate has recently been shown to be useful in non-acid related gastrointestinal disease as well. In fact, sucralfate has also been administered topically in patients with radiation-induced mucosal procto-sigmoiditis or ulcerative colitis with surprising results. The drug is actually able to form a physical barrier between epithelium and damaging agents (-bile salts, drugs, refluxate...). Moreover, sucralfate increases the local levels of fibroblast growth factors and induces a rise in the mucosal concentration of prostaglandins which are considered important factors in mucosal healing. The aim of this paper is to describe the current and probably forthcoming uses of sucralfate in the field of gastrointestinal disorders. Moreover, we investigate the role of sucralfate as a reliable means to prevent the occurrence of reflux-like symptoms after Helicobacter pylori eradication and in the management of Helicobacter pylori negative patients affected by non-ulcer dyspepsia.

Venous leg ulcers are an important medical issue due to their high incidence in the elderly and the lack of a standard curative approach. Apart from surgical therapy, different medical treatments to effect ulcer wound repair and regeneration are currently being investigated. Sucralfate is a cytoprotective agent employed to prevent or treat several gastrointestinal diseases such as gastroesophageal reflux, gastritis, peptic ulcer, stress ulcer and dyspepsia. In this study we evaluated the efficacy, safety and tolerability of topical sucralfate (SUC-LIS 95) on the healing of chronic venous leg ulcers in 50 patients by a double-blind, placebo-controlled, randomized study. Our results indicated that the daily application of SUC-LIS 95 to non-infected post-phlebitis/vascular ulcers, for a median period of 42.0 days, led to complete healing in 95.6% of patients, against only 10.9% of cases with a matched placebo. A significant improvement was obtained in the SUC-LIS 95-treated patient group with regard to local tissue inflammation as well as pain and burning, and consequently, in ulcer size and the evolution of granulation tissue. Our findings were corroborated for selected patients by the morphological analysis of biopsies obtained before and after treatment. Using ultrastructural analysis we demonstrated that the topical use of SUC-LIS 95 was able to affect neoangiogenesis, increase wound contraction, promote re-epithelialization of the wound area and diminish the inflammatory reaction. Overall, our results indicated that patients with chronic venous ulcers show improvement after the use of topical sucralfate.

Proton-pump inhibitors (PPIs) remain the leading evidence-based therapy for upper gastrointestinal disorders, including gastroesophageal reflux disease, dyspepsia, and peptic ulcer disease. The effectiveness of PPIs has led to overutilization in multiple treatment arenas, exposing patients to an increasing number of potential risks. The overutilization of PPIs in ambulatory care settings is often a result of failure to re-evaluate the need for continuation of therapy, or insufficient use of on-demand and step-down therapy. PPI overutilization in the inpatient setting is often a result of inappropriate stress ulcer prophylaxis (SUP) in nonintensive care unit patients, and failure to discontinue SUP prior to hospital discharge. Potential consequences of prolonged PPI therapy include hypergastrinemia, enterochromaffin-like cell hyperplasia, and parietal cell hypertrophy, leading to rebound acid hypersecretion. PPIs have been linked via retrospective studies to increased risk of enteric infections including Clostridium difficile-associated diarrhea, community-acquired pneumonia, bone fracture, nutritional deficiencies, and interference with metabolism of antiplatelet agents. Reducing inappropriate prescribing of PPIs in the inpatient and outpatient settings can minimize potential for adverse events, and foster controllable cost expenditure.

The advent of powerful acid-suppressive drugs, such as proton pump inhibitors (PPIs), has revolutionized the management of acid-related diseases and has minimized the role of surgery. The major and universally recognized indications for their use are represented by treatment of gastro-esophageal reflux disease, eradication of Helicobacter pylori infection in combination with antibiotics, therapy of H. pylori-negative peptic ulcers, healing and prophylaxis of non-steroidal anti-inflammatory drug-associated gastric ulcers and control of several acid hypersecretory conditions. However, in the last decade, we have witnessed an almost continuous growth of their use and this phenomenon cannot be only explained by the simple substitution of the previous H2-receptor antagonists, but also by an inappropriate prescription of these drugs. This endless increase of PPI utilization has created an important problem for many regulatory authorities in terms of increased costs and greater potential risk of adverse events. The main reasons for this overuse of PPIs are the prevention of gastro-duodenal ulcers in low-risk patients or the stress ulcer prophylaxis in non-intensive care units, steroid therapy alone, anticoagulant treatment without risk factors for gastro-duodenal injury, the overtreatment of functional dyspepsia and a wrong diagnosis of acid-related disorder. The cost for this inappropriate use of PPIs has become alarming and requires to be controlled. We believe that gastroenterologists together with the scientific societies and the regulatory authorities should plan educational initiatives to guide both primary care physicians and specialists to the correct use of PPIs in their daily clinical practice, according to the worldwide published guidelines.
