The said compositions are useful in the treatment of gastric acid related disor ders such as gastro esophageal reflux disease, reflux esophagitis, peptic ulcer, gastric ulcer, heartburn, sour stomach, acid inges tion, upset stomach and/or pain associated with heartburn, sour stomach and acid ingestion, bloating, fullness, dyspepsia, noctur nal heartburn, disorders not manifested by the presence of ulcerations in the gastric mucosa, including chronic active or atrophic gastritis, and Zollinger-Ellison syndrome. PHARMACEUTICAL COMPOSITIONS COMPRISING OF PROTON PUMP INHIBITOR, PROKINETIC AGENT AND ALGINIC ACID FIELD OF THE INVENTION The present invention relates to oral pharmaceutical compositions and process for preparing compositions comprising at least one gastric acid suppressing agent, at least one prokinetic agent and at least one alginic acid optionally with pharmaceutically acceptable excipients; such that the gastric acid suppressing agent is present in a delayed release form, prokinetic agent is present in a bimodal release form such as an immediate release form, and a delayed release form to provide a dose with a lag time form and alginic acid is present in an immediate release form. The said compositions are useful in the treatment of gastric acid related disorders such as gastro esophageal reflux disease, reflux esophagitis, peptic ulcer, gastric ulcer, heartburn, sour stomach, acid ingestion, upset stomach and/or pain associated with heartburn, sour stomach and acid ingestion, bloating, fullness, dyspepsia, nocturnal heartburn, disorders not manifested by the presence of ulcerations in the gastric mucosa, including chronic active or atrophic gastritis, and Zollinger-Ellison syndrome. BACKGROUND OF THE INVENTION Gastro esophageal reflux disease (GERD), reflux esophagitis, peptic ulcer, gastric ulcer and other gastric acid related disorders are disorders having a pathogenesis related to reduced gastric motility and release of excessive gastric acid. Apart from lifestyle modifications, GERD and gastric ulcer have been successfully treated with a range of gastric acid inhibitors, such as ranitidine and omeprazole, which are acid-suppressing agents. Stimulation of gastric motility has been proposed to accelerate the healing of gastric ulcer. Prokinetic agents, such as domperidone, are known to enhance gastrointestinal motility and prevent duodenogastric reflux, and are widely used to treat GERD. Proton pump inhibitors, H2 receptor antagonists and prokinetic agents have been used in combination to treat gastric ulcer and other related disorders. Proton pump inhibitors (PPIs) are a class of acid-labile pharmaceutical compounds that I block gastric acid secretion pathways. Exemplary proton pump inhibitors include, omeprazole (Prilosec.RTM.), lansoprazole (Prevacid.RTM.), esomeprazole (Nexium.RTM.), rabeprazole (Aciphex.RTM.), paπtoprazole (Protonix.RTM.), pariprazole, tenatoprazole, and leminoprazole. The drugs of this class suppress gastrointestinal acid secretion by the specific inhibition of the H.sup.+/K.sup.+-ATPase enzyme system (proton pump) at the secretory surface of the gastrointestinal parietal cell. Most proton pump inhibitors are susceptible to acid degradation and, as such, are rapidly destroyed in an acidic pH environment in the stomach. Therefore, proton pump inhibitors are often administered as enteric-coated dosage forms in order to permit release of the drug in the duodenum after having passed through the stomach. Prilosec.RTM. (omeprazole) is formulated as enteric-coated granules in gelatin capsules. Prevacid.RTM. (lansoprazole) is available as enteric-coated granules in gelatin capsules, and as enteric-coated microspheres for use as a liquid suspension. Nexium.RTM. (esomeprazole magnesium) is enteric-coated granules in gelatin capsules. Proton pump inhibitors are typically prescribed for short-term treatment of active duodenal ulcers, gastrointestinal ulcers, gastroesophageal reflux disease (GERD), severe erosive esophagitis, poorly responsive symptomatic GERD, and pathological hypersecretory conditions such as Zollinger Ellison syndrome. These above-listed conditions commonly arise in healthy or critically ill patients of all ages, and may be accompanied by significant upper gastrointestinal bleeding. H2-receptor antagonists are frequently employed to treat disorders linked to the hypersecretion of gastric acid, for example the treatment of gastric ulcers, as they inhibit the secretion of gastric acid. Histamine H2-receptor antagonists may be chosen from a series of well-known products such as cimetidine, ranitidine, famotidine, etc. Prokinetic agents may be prescribed in the treatment of various gastrointestinal diseases, such as gastroesophageal reflux disease (GERD), inflammatory bowel disease, or to treat primary gastrointestinal motility disorders, such as diffuse esophageal spasm or irritable bowel syndrome. Motility disorders of the gastrointestinal tract may be caused by neural, muscular or receptor damage dysfunction. Prokinetic agents would be useful in concomitant therapy with proton pump inhibitors to treat patients with GERD, erosive esophagitis or functional dyspepsia. PPI and prokinetic agent combinations increase the tone of the lower esophageal sphincter, decrease the number of transient lower esophageal relaxations, and increase gastric emptying while the proton pump inhibitor administered decreases the volume of gastric juice available for reflux into the esophagus and increases the pH so Jhat refluxed gastric contents are much less injurious to the esophageal mucosa. Alginic acid and its salts with sodium and potassium bicarbonate have shown that, after entering the stomach environment they form a viscous suspension or a gel exerting protecting activity over gastric mucosa. The scientific and patent literature on its activity is wide. Alginates may be used alone in the treatment of heartburn. They have a short duration of action but are seen as inexpensive and safe. Alginates further give some mechanical protection against reflux or gastric acid into the esophagus. Sodium alginate forms a 'raft' which floats to the top of the stomach, forming a barrier between the acid and the oesophagus, thus preventing acid refiuxing into the oesophagus and protecting the mucosa from further irritation. The main advantage of alginates is that they provide fast relief of symptoms. Esomeprazole magnesium is bis (5-methoxy-2-[(S)-[(4-methoxy-3,5-dimethyl-2- pyridinyl) methyl]sulf ϊnyl]-lH-benzimidazole-l-yl) magnesium trihydrate, a compound that inhibits gastric acid secretion. Esomeprazole is the S-isomer of omeprazole, which is a mixture of the S- and R- isomers. Its molecular formula is (C 17H 18NsO S)2 Mg.3 H O with molecular weight of 767.2 as a trihydrate and 713.1 on an anhydrous basis. Metoclopramide is 4-amino-5-chloro-N-(2-(diethylamino) ethyl)-2-methoxybenzamide and a potent dopamine receptor antagonist used for its antiemetic and prokinetic properties.

Legal Status: Prescription only product. VI.2 Elements for a public summary VI.2.1 Overview of disease epidemiology Nausea and vomiting associated with chemotherapy and radiotheraphy: One of the most distressing symptoms for patients undergoing both surgery and chemotherapy is nausea and vomiting. These symptoms have a significant impact on quality of life and can lead to malnutrition, inability to respond to treatment and an increased length of hospitalization. Emesis is more commonly associated with chemotherapeutic agents; however, radiation‐induced nausea and vomiting (RINV) can affect a significant proportion of patients, depending on the treated area, dose fractionation, and volume of radiotherapy. The relative risk for developing nausea and vomiting with chemotherapy ranges from 30 to 90% and is dependent upon the chemotherapeutic agent used. Relative risk for nausea and vomiting with radiation therapy is approximately 40%.2,3,4,5 Post‐operative nausea and vomiting Postoperative nausea and vomiting (PONV) is a major source of patient dissatisfaction and is the leading cause of discharge delays and unanticipated postsurgical hospital admissions. In the absence of pharmacological treatment, the rate of PONV is approximately 30% in general population, and can be as high as 70% in patients at highest risk. Several risk factors as surgery type, female gender, non‐smoker status, history of postoperative nausea and vomiting or motion sickness and post‐operative opioid use have been acknowledged. Additionally, post‐ operative vomiting (POV) occurs twice as frequently in children as in adults, increasing until puberty and then decreasing to adult incidence rates.

  • Therapeutic Class Overview Irritable Bowel Syndrome Agents
    Therapeutic Class Overview Irritable Bowel Syndrome Agents Therapeutic Class Overview/Summary: This review will focus on agents used for the treatment of Irritable Bowel Syndrome (IBS).1-5 IBS is a gastrointestinal syndrome characterized primarily by non-specific chronic abdominal pain, usually described as a cramp-like sensation, and abnormal bowel habits, either constipation or diarrhea, in which there is no organic cause. Other common gastrointestinal symptoms may include gastroesophageal reflux, dysphagia, early satiety, intermittent dyspepsia and nausea. Patients may also experience a wide range of non-gastrointestinal symptoms. Some notable examples include sexual dysfunction, dysmenorrhea, dyspareunia, increased urinary frequency/urgency and fibromyalgia-like symptoms.6 IBS is defined by one of four subtypes. IBS with constipation (IBS-C) is the presence of hard or lumpy stools with ≥25% of bowel movements and loose or watery stools with <25% of bowel movements. When IBS is associated with diarrhea (IBS-D) loose or watery stools are present with ≥25% of bowel movements and hard or lumpy stools are present with <25% of bowel movements. Mixed IBS (IBS-M) is defined as the presence of hard or lumpy stools with ≥25% and loose or water stools with ≥25% of bowel movements. Final subtype, or unsubtyped, is all other cases of IBS that do not fall into the other classes. Pharmacological therapy for IBS depends on subtype.7 While several over-the-counter or off-label prescription agents are used for the treatment of IBS, there are currently only two agents approved by the Food and Drug Administration (FDA) for the treatment of IBS-C and three agents approved by the FDA for IBS-D.

Abstract The 5-hydroxytryptamine (5-HT; serotonin) 5-HT3 receptor is an excitatory ligand- gated ion channel expressed in for example the brain and the gastrointestinal tract. Two major subtypes of the receptor have been studied in the most detail; the homomeric 5-HT3A receptor and the heteromeric 5-HT3AB receptor. 5-HT3 receptor antagonists are used clinically to treat chemotherapy induced and post-operative nausea and vomiting, and demonstrate symptomatic relief in diarrhoea-predominant irritable bowel syndrome (IBS-d); but unfortunately, these medications cause adverse effects such as constipation or rarely ischemic colitis in the latter condition. This study has characterised the pharmacology of two structurally distinct 5-HT3 receptor partial agonists (vortioxetine and CSTI-300); and identified the unique binding properties of the cryptic orthosteric modulator 5-chloroindole (Cl-indole) for the human (h) 5-HT3 receptor.
