Helicobacter pylori, profoundly termed as H. pylori, is a gram negative microorganism and a main causative pathogen for gastritis, peptic ulcers, duodenal ulcers and mucosa associated lymphatic tissue (MALt) lymphoma that leads to gastric cancer in infected patients, if uncontrolled in the stipulated time. Until 1994, half of the total world population was suffering from H. pylori infection. based on a WHO survey it is predicted that by 2020, H. pylori infection will be the top ten of the leading causes of death worldwide. this current scenario indicates that it is high time for pathologists, pharmacologists and pharmaceutical formulation development scientists to come together to address the challenge of managing H. pylori infection. this article briefly highlights symptoms, diagnostic tests and various treatment regimens reported for the management of the H. pylori infection. the present article mainly focuses upon novel drug delivery systems developed in the last decade, with special emphasis on the need of gastro retentive drug delivery systems (GRDDS), for effective management of H. pylori infection. targeted drug delivery to the stomach mucosal layer is believed to provide a site-specific effect for eradication of H. pylori. the authors have analysed various reported approaches to deliver drugs for the management of H. pylori infection. It is evident that efficacious results can be obtained with a multi-particulate drug delivery system as compared to a conventional single unit dosage form.

The use of various bioerodable polymers as drug delivery systems has gained considerable interest in recent years. Among some of the shapes used as delivery systems are films, rods and microcapsules. The work presented here will deal with the techniques we have utilized for the analysis of the tissue reaction to and actual biodegradation of injectable microcapsules. This work has utilized light microscopic (LM), transmission (TEM) and scanning (SEM) electron microscopic techniques. The design of our studies has utilized methodology that would; 1. best characterize the actual degradation process without artifacts introduced by fixation procedures and 2. allow for reproducible results.In our studies, the gastrocnemius muscle of the rat was chosen as the injection site. Prior to the injection of microcapsules the skin above the sites was shaved and tattooed for later recognition and recovery. 1.0 cc syringes were loaded with the desired quantity of microcapsules and the vehicle (0.5% hydroxypropylmethycellulose) drawn up. The syringes were agitated to suspend the microcapsules in the injection vehicle.
