What this trial studies

This clinical trial aims to evaluate the effectiveness of Jinsang Liyan capsules in combination with proton pump inhibitors (PPI) compared to PPI alone for treating Laryngopharyngeal Reflux Disease (LPRD). Participants will be randomly assigned to receive either the Jinsang Liyan capsule with rabeprazole or a placebo with rabeprazole. The study will assess symptom improvement at 4 and 8 weeks post-treatment. The goal is to determine if the combination therapy provides superior relief from LPRD symptoms.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-65 diagnosed with LPRD who have not taken antacids or gastrointestinal motility drugs in the two weeks prior to enrollment.

Not a fit: Patients with severe digestive system diseases or acute upper respiratory infections may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could offer improved symptom relief for patients suffering from LPRD.

How similar studies have performed: Previous studies have shown positive outcomes with similar treatments for LPRD, indicating potential for success in this approach.
