Refractory dyspeptic cases, who fail to respond conventional Received: June 22, 2015; Accepted: July 09, 2015; treatment of dyspepsia can be managed with antidepressant or pro kinetic Published: July 10, 2015 drugs. Levosulpiride is an atypical antipsychotic, acts by blocking the presynaptic D2 dopaminergic receptor in the dopaminergic pathway. It was found that levosulpiride have more efficacy in management of dyspeptic symptoms in comparison to antisecretary agents (cimetidine, ranitidine) and prokinetic agents (metaclopramide, domperidone). Levosulpiride is as effective as cisapride in management of dyspepsia, having better tolerability, and relatively milder adverse events. Levosulpiride improves the dyspeptic symptoms like pain, discomfort, fullness, bloating of abdomen, early satiety, nausea, vomiting, associated anxiety symptoms, and health related quality of life impaired by dyspeptic symptoms. Levosulpiride quicken gastric and gall bladder emptying. It also has gastro kinetic effect and improves glycemic control in diabetic gastroparesis. Galactorrhoea, somnolence, fatigue and headache are common adverse event seen with levosulpiride therapy. Majority of adverse events were occurred in first fifteen days of treatment with levosulpiride, and they improve gradually without discontinuation of treatment. Unlike cisapride, levosulpiride is devoid of serious cardiovascular adverse effect. Keyword: Levosulpiride; Dyspepsia; Gastroparesis Abbreviations factors [1,2].

The prevalence of Dyspepsia is a group of symptoms referable to upper uninvestigated dyspepsia (UD) varies from 7% to 45%. The difference gastrointestinal tract rather than diagnosis itself [1,2]. It consists of of this large variation probably because of variation of difference in variable combination of symptoms of upper gastrointestinal tract definition of dyspepsia and the different population studied [2,7]. including abdominal discomfort or pain, postprandial fullness, Population based study from Iran found that females, NSAIDs users, abdominal bloating, early satiety, nausea, vomiting, heartburn and water pipe smokers, persons having psychological distress, recurrent acid regurgitation [1,2]. There is a group of patients who do not headache, anxiety, nightmares, past history of gastrointestinal disease, have definite structural or biochemical cause for their symptoms, are high caffine intake and persons from poor socio economical status are considered for suffering from functional dyspepsia (FD) [1,2]. There more likely to suffer from dyspepsia, while fruits, vegetables, dates, are several pathophysiological correlates have been identified for honey, walnut, yogurt, bread and caraway seeds are protective in functional dyspepsia, including gastro intestinal motor abnormalities, dyspepsia [4,8]. There are 2-4% patients attending primary care clinic altered visceral sensation, central nervous system- enteral nervous having presenting complaint of dyspepsia [3,9] and this percentage system (CNS-ENS) integration dysfunctions and psychological may go beyond 50% in specialist gastroenterology clinic [10].

These agents have quality of life instrument (EQ-5D) including mobility, self-care, properties to block enteric inhibitory D2; in this respect levosulpiride usual activity, pain/ discomfort, anxiety / depression in patients with is selective D2 receptor antagonist with prokinetic activity [20,22]. dyspepsia [2,11,12]. It helps in controlling gastro intestinal motility by acting through Methods dopaminergic pathway and its action on 5-HT4 receptor have role in management in functional dyspepsia [20,23]. High efficacy of All published articles including clinical trials, case reports and levosulpiride in management of dyspeptic symptoms with limited review articles were searched in electronic database by using search side effect is reported in many studies [20,24,25,26,27]. engines like PubMed, Psych Info and Google Scholar.

In comparison to dextro odynophagia, gastrointestinal blood loss and family history of enantiomer or racemic mixture of drug, levosulpiride shows better carcinoma [13,14].
