Gaviscon Advance which consists of sodium alginate significantly reduces acid reflux and heartburn. Gaviscon forms a 'gate' near the top of the stomach and neutralizes acid. Other treatments like esomeprazole are viable but Gaviscon Advance is equally and possibly more effective as well as safer (Dettmar and Strugala, 2008; Giannini et al., 2006; Pouchain et al., 2012). Gaviscon Advance used in conjunction with esomeprazole is a viable and highly effective option (Dettmar et al., 2006; Reimer et al., 2016)
