Comparative Study of Alginate and Omeprazole in Symptomatic Treatment of Non-erosive Gastroesophageal Reflux Disease.

Gastroesophageal reflux disease is widely reported most prevalent disease of the gastrointestinal tract. The burden of gastroesophageal reflux disease (GERD) is increasing in Asia and the majority of patients have non-erosive reflux disease. This prospective, open label, non random (consecutive), experimental study was performed due to compare the therapeutic efficacy of alginate and omeprazole in relieving symptoms of non erosive reflux disease (NERD) and was carried out in the Outpatient Department of Gastroenterology, Dhaka Medical College Hospital, Dhaka, Bangladesh from December 2013 to May 2014. Sixty patients were enrolled for this study and were divided into two groups. Among them, 30 subjects were assigned to the omeprazole group (Group I) and 30 subjects to the alginate group (Group II). Omeprazole 20mg enteric coated capsule daily and alginate 10ml three times daily were administered 14 days in this study. In ITT analysis, achieving complete symptom relief (heart burn) was 56.7% in alginate group & 60% in omeprazole group. Statistically which was not significant (p=0.793). In PP analysis, this was 65.4% and 66.7% respectively. In this study, the overall satisfaction of omeprazole & alginate was more than 86% and the mean duration of heart burn free was found 5.0±4.0 days in Group I and 3.65±2.8 days in Group II. The difference was not statistically (p>0.05) significant between two groups in this study. Therapeutic efficacy and safety profiles of alginate were comparable to omeprazole after two weeks treatment in NERD subjects. So alginate may be considered as a relevant and effective alternative medication in non-erosive reflux.
