Email: [email protected] Received: 04 July 2017, Revised and Accepted: 16 August 2017 ABSTRACT Objective: The objective of the study was to compare the effect between alginate (Alg)-based raft-forming and Alg liquid on healing gastroesophageal reflux disease (GERD) and gastric ulcer in rats. Methods: Each of the 18 fasted rats was given 1 ml acidified pepsin. Then, rats were divided into three groups. Each group consisted of six rats. Group 1 (negative control) was orally given 1 ml distilled water, Group 2 was given 1 ml Alg-based raft-forming liquid, and Group 3 was given 1 ml Alg liquid. Then, the abdomen of rats was incised under anesthesia with ketamine, and then both their pylorus and the forestomach were ligated to form gastric reflux. After 4 hrs, all rats were killed with chloroform and their esophagus and stomach were examined macroscopically and microscopically (histopathology). Results: On macroscopic observation, all of the Group 1 rats (negative control) showed esophageal lesions and gastric lesions. Four rats of Group 2 (given Alg-based raft-forming) showed no esophageal lesion and two more rats showed a slight lesion, but all of the tested rats showed gastric lesions.

In order to understand various physiological difficulties to achieve gastric retention, we have summarized important factors controlling gastric retention time. We have reviewed various gastro retentive approaches designed and developed until now i.e. floating drug dosage systems (FDDS), swelling or expanding systems, mucoadhesive systems, high density system, Raft forming system, magnetic systems. Among these systems, the review summarizes the special focus on raft forming approach which comes under floating drug delivery system. Raft system incorporates alginate gels which have carbonate components react with gastric acid causes bubbles and this enables floating. Finally, Evaluation, advantages, disadvantages, future potential and marketed preparation of raft forming approach in gastro retentive drug delivery systems were covered.

  • The Role of Alginate-Based Therapy in Gastroesophageal Reflux Disease
    Romanian Journal of MEDICAL PRACTICE General articles Ref: Ro J Med Pract. 2020;15(3) DOI: 10.37897/RJMP.2020.3.5 The role of alginate-based therapy in gastroesophageal reflux disease Assoc. Prof. Ana-Maria SINGEAP1,2, MD, PhD, Assist. Prof. Laura HUIBAN1,2, MD, PhD student, Assist. Prof. Stefan CHIRIAC1,2, MD, PhD, Assist. Prof. Tudor CUCIUREANU1,2, MD, PhD student, Prof. Anca TRIFAN1,2, MD, PhD, FRCP 1 “Gr.T. Popa” University of Medicine and Pharmacy, Iasi, Romania 2 Institute of Gastroenterology and Hepatology, “St. Spiridon” Emergency Hospital, Iasi, Romania Abstract Gastroesophageal reflux disease (GERD) is one of the most common digestive pathologies, with worldwide spread and increasing incidence. Due to the chronic nature of this condition, the dreaded complications that can occur during evolution and the negative impact on patients' quality of life, it is imperative to administer symptomatic treatment to eliminate or improve symptoms, cure erosive esophagitis and prevent recurrences and complications. Alginic acid formulations have a unique, particular mechanism of action, acting as a long-lasting physical barrier floating on the surface of the gastric pool, displacing the postprandial gastric acid pocket and protecting esophagus mucosa during reflux episodes. Numerous studies evaluated the efficacy of alginate treatment in GERD, by comparison to antacids, proton pump inhibitors (PPIs), histamine 2 receptor antagonists (H2RAs), or placebo. While most studies found superiority of alginate treatment when compared to antacids or to placebo, PPIs treatment was overall more effective than alginate in controlling GERD symptoms. There were some trials that reported alginate non-inferiority when compared to PPIs, especially in the setting of NERD.

  • Alginate Forming In-Situ Gel for Treating Peptic Ulcers and Reflux Disorders
    JPSBR: Volume 5, Issue 2: 2015 (172-179) ISSN NO. 2271-3681 A Review On: Alginate Forming In-Situ Gel for Treating Peptic Ulcers and Reflux Disorders I.S Sengupta*1, SH Shah2, N. Shah2 1. Student of Department of Pharmaceutical technology, M.Pharm 4th semester, L.J institute of pharmacy, Ahmedabad, Gujarat, India 2. HOD of Department of Pharmaceutical technology, L.J institute of pharmacy, Ahmedabad, Gujarat 3. Assistant professor of Department of Pharmaceutical technology, L.J institute of pharmacy, Ahmedabad, Gujarat, India ABSTRACT: The oral delivery of drugs with a narrow absorption window in the gastrointestinal tract (GIT) is often limited by poor bioavailability with conventional dosage forms due to incomplete drug release and short residence time at the site of absorption. In-situ gel provides the best way to overcome problems of immediate release and short gastrointestinal residence of liquids. The in situ gel dosage form is a liquid before administration and after it comes in contact with gastric contents due to one or more mechanisms gets converted to gel which floats on gastric contents. This achieves increased residence as well as sustained release. This approach is useful for systemic as well as local effect of drugs administered. In the presence of gastric acid, alginates precipitate, forming a gel.Alginate-based raft-forming formulations usually contain sodium or potassium bicarbonate; in thepresence of gastric acid, the bicarbonate is converted to carbon dioxide which becomes entrapped within the gel precipitate, converting it into a foam which floats on the surface of the gastric contents, much like a raft on water.

  • Evaluation of Alginate Beads of an Antiulcer Drug Using Experimental Design: Formulation and in Vitro Evaluation
    Available online a t www.scholarsresearchlibrary.com Scholars Research Library Der Pharmacia Lettre, 2015, 7 (12):338-343 (http://scholarsresearchlibrary.com/archive.html) ISSN 0975-5071 USA CODEN: DPLEB4 Evaluation of alginate beads of an antiulcer drug using experimental design: Formulation and in vitro evaluation Kavita Bahmani, D. C. Bhatt and Priyanka Saharan Pharmaceutics Division, Department of Pharmaceutical Sciences, Guru Jambheshwar university of Science and Technology, Hisar _____________________________________________________________________________________________ ABSTRACT Rabeprazole sodium is a proton pump inhibitor widely used as an antiulcer drug in gastric ulcers and various gastro-esophaegal diseases. Rabeprazole sodium is absorbed in the gastrointestinal tract and because it is unstable under acidic conditions, enteric delivery systems are required. The aim of the present work was to study the effect of formulation variables e.g., sodium alginate concentration (X1), calcium chloride concentration(X2), on drug entrapment efficiency (Y1), in-vitro release profiles (Y2) and particle size (Y3) of multi-particulates system of Rabeprazole sodium. Experiments were designed according to 3 2 factorial design. Alginate beads were formulated using ionotropic gelation method after preparation the beads were coated with Eudragit RS 100. Developed formulations were characterized and evaluated on the basis of particle size, entrapment efficiency and drug release studies. The formulation variables were optimized by response surface methodology (RSM) Key words : Rabeprazole sodium, factorial design, alginate beads, sodium alginate _____________________________________________________________________________________________ INTRODUCTION Proton-pump inhibitors (PPIs) have been widely used for the management of a variety of acid-related disorders. However, as PPIs are acid-labile, they need to be protected from the destructive effects of gastric acid when administered orally.
