Alginic acid and soluble alginate salts have been applied for many years in the treatment of anti-reflux. When reaching the stomach, alginates react to produce an acid gel. This then reacts with calcium carbonate to produce a buoyant gel/foam or ‘gastric raft’, which provides a mechanical barrier against stomach reflux. Gastric rafts provide cost effective, immediate relief to consumers.
Furthermore, these rafts can potentially be combined with other medicines to achieve longer lasting label claims.
