Magnesium alginate effectively treats LPR
Magnesium alginate in patients with laryngopharyngeal reflux.
High relevance: clear findings.
We examined the role of magnesium alginate in treating laryngopharyngeal reflux (LPR), which causes symptoms like voice issues, swallowing difficulties, and coughing. In a study involving 100 outpatients, patients were treated with alginate for two months, visiting at the start and then at 15, 30, and 60 days.

The results were promising, showing a significant reduction in all symptoms assessed. This suggests that magnesium alginate could be a safe and effective alternative for managing LPR, especially for those who cannot fully rely on conventional treatments like proton pump inhibitors.

Magnesium alginate reduces infant reflux
Magnesium Alginate in Gastro-Esophageal Reflux: A Randomized Multicenter Cross-Over Study in Infants.
Costs less than thickened formula
We conducted a multicenter crossover study to see if magnesium alginate could alleviate reflux symptoms in infants. A total of 72 infants participated, receiving either magnesium alginate or a thickened formula in alternating phases.

Our findings showed a significant reduction in reflux symptoms across all infant groups. However, there was no significant difference in effectiveness between the two treatments. Importantly, using magnesium alginate also yielded cost savings of about €4.60 per infant compared to the thickened formula.

Thus, magnesium alginate appears to be a cost-effective option without sacrificing symptom relief.

Gaviscon® Advance effectively treats LPR
Gaviscon® Advance alone versus co-prescription of Gaviscon® Advance and proton pump inhibitors in the treatment of laryngopharyngeal reflux.
No additional benefit seen.
We explored the effectiveness of Gaviscon® Advance, both alone and alongside proton pump inhibitors (PPIs), in treating laryngopharyngeal reflux (LPR).

One hundred patients participated in this study, all treated with Gaviscon® Advance and monitored over three months.

The findings indicated that while Gaviscon® Advance is effective on its own, combining it with a high-dose PPI did not enhance symptom relief.

This suggests that Gaviscon® Advance can be a sufficient treatment for LPR without needing the added PPI.

Significant reflux relief
The cooling vitamins arrived extremely quickly, even faster than expected. The quality is fantastic and the packaging perfect! The taste is almost non-existent. However, the tablet contains two doses; if you need to take two per day, remember to break the pill in half. I found that after taking calcium and vitamin D, my digestion improved significantly. Endless heartburn began to fade and the frequency of reflux attacks was greatly reduced. My pancreas feels much better, and of course, my bones and immunity are in order!

Healthy lifestyle improvement
More than anything, I feel healthy after eating. Thank you so much, my herb! The quality is excellent, do I need to say more? I started taking this product, which is meant to be swallowed after meals. In the past, I suffered from reflux esophagitis for a long time, but this product has proven reliable. I often face unexpected stresses while living outside and I refuse to succumb to them, so I’ll keep striving for a healthy mind and body through various challenges, not just exercise. With this product, I notice the effect is certain.

Gaviscon DA effectively neutralizes acid
Two placebo-controlled crossover studies in healthy subjects to evaluate gastric acid neutralization by an alginate-antacid formulation (Gaviscon Double Action).
High relevance for reflux treatments
We explored how Gaviscon Double Action, a combination of alginate and antacid, affects gastric acid levels. In a carefully designed crossover study, we monitored intragastric pH in healthy volunteers after administering Gaviscon DA versus a placebo.

The results showed a clear advantage for Gaviscon DA, with pH levels reaching 4 or higher nearly 47% of the time, compared to just 5% for the placebo. This confirms that Gaviscon DA effectively neutralizes gastric acid, enhancing the understanding of how its components work together for reflux relief.

Calcium's role in reflux unclear
The Tibetan Formula Cong zhi 6 in the ORL (ENT) Practice: Experiences with Laryngopharyngeal Reflux.
Calcium not specifically isolated
We explored the effects of a multi-herbal Tibetan formula known as Cong zhi 6, which includes calcium carbonate, on individuals suffering from laryngopharyngeal reflux (LPR). Our focus was to understand whether calcium plays a role in alleviating reflux symptoms.

In our examination of ten patients who took Cong zhi 6, we observed significant improvements in both reflux symptoms as measured by the Reflux Symptom Index (RSI) and findings from laryngoscopy assessed via the Reflux Finding Score (RFS). While the results were promising, they did not isolate the specific impact of calcium.

Consequently, we cannot affirmatively state that calcium alone has a beneficial effect on reflux. The study indicated that LPR symptoms improved overall, but we remain uncertain about calcium's individual efficacy in this context. This highlights the need for further research to pinpoint the mechanisms at play in reducing reflux symptoms.

Banxia Houpu Decoction shows promise
Efficacy evaluation and exploratory analysis of influencing factors of Banxia Houpu Decoction in the treatment of refractory gastroesophageal reflux disease.
High relevance for GERD treatments
We evaluated how Banxia Houpu Decoction, a traditional Chinese remedy, can help patients with refractory gastroesophageal reflux disease (RGERD). In our study involving 89 patients, we compared this decoction to standard Western treatments, including proton pump inhibitors with added magnesium aluminum carbonate.

Results showed that the decoction significantly improved throat burning, swallowing difficulties, and hiccups more effectively than Western treatments. However, the Western medicine group had better relief for heartburn and gastric burning sensations.

Factors like age and gastroesophageal flap valve grade also impacted treatment effectiveness.

Weisu granules significantly improve reflux
[Clinical observation of Weisu granules in treating laryngopharyngeal reflux].
High efficacy; significant results
We aimed to observe how effective Weisu granules are on laryngopharyngeal reflux by randomly assigning 180 patients into three groups.

The experimental group received a combination of Lanqin oral solution and Weisu granules, while the control groups used either Lanqin alone or Esomeprazole with Lanqin.

After four weeks, the experimental group showed a remarkable 91.7% improvement, much higher than the 73.3% in control group A. Although the experimental group differed significantly from control group A, results were similar to control group B, indicating no major advantage over Esomeprazole.
