The effectiveness of drug class changes was assessed through the reflux symptom score (RSS) change. Signs were evaluated with the Reflux Sign Assessment. The RSS reduction was used to categorize the therapeutic responses as mild (20%\u201040% RSS reduction), moderate (40.1%\u201060% RSS reduction), high (60.1%\u201080%), and complete (&gt;80%).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Among the 334 medical records, 74 (22.2%) patients had refractory LPRD defined as no RSS change in the pre\u2010 to 3\u2010month posttreatment. The mean age was 52.6\u2009\u00b1\u200915.5 years. Changing drug class was associated with significant 3\u2010 to 6\u2010month posttreatment reductions of RSS and RSA. Thirty patients (39%) did not experience symptom reduction after changing drugs. Changing alginate to magaldrate and magaldrate to alginate was associated with the highest responder rate (76.9%). Changing PPI and alginate\/magaldrate molecules led to a response rate of 62.5%. In patients initially treated with a combination of PPI and alginate or magaldrate, changing PPI without changing alginate\/magaldrate led to a 37.5% response rate. The baseline RSS was predictive of the 3\u2010 and 6\u2010month RSS (therapeutic response).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Changing drug class, especially
