What this trial studies

This clinical trial investigates the effects of Qinqiao Yan Shu Granules on patients with acute pharyngitis characterized by the wind-heat syndrome. It employs a block-randomized, double-blind, dose-escalation design across multiple centers, enrolling a total of 216 participants divided into high-dose, low-dose, and extremely low-dose groups. The trial aims to assess symptom improvement and safety of the granules compared to a control group receiving a very low dose. Participants will be monitored for changes in their condition and any adverse effects.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 65 who have been diagnosed with acute pharyngitis and exhibit specific symptoms related to the wind-heat syndrome.

Not a fit: Patients with pharyngeal symptoms due to other infections or conditions, such as measles or influenza, will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new effective option for managing acute pharyngitis symptoms.

How similar studies have performed: While this approach is novel in the context of Qinqiao Yan Shu Granules, similar studies on herbal treatments for acute pharyngitis have shown promising results.
