Summary

This is a multicenter, randomized, controlled, prospective clinical trial designed to observe and evaluate the safety and efficacy of Modified Dahuang Huanglian Xiexin Mouthwash for the prevention of radiotherapy-induced oral mucositis (RTOM).

Participants will be randomly assigned to receive either the Modified Dahuang Huanglian Xiexin Mouthwash or Placebo Mouthwash. The study aims to assess the preventative effect on RTOM in patients undergoing radiotherapy.

Conditions

  • Radiotherapy-Induced Oral Mucositis
  • Stomatitis
  • Oral Mucositis
  • Radiotherapy Side Effects

Interventions

DRUG

Modified Dahuang Huanglian Xiexin Mouthwash

A Chinese herbal mouthwash formulation derived from the classic formula Dahuang Huanglian Xiexin Decoction, with additional ingredients to enhance its properties for radiation-induced oral mucositis. The active ingredients include Rhei Radix et Rhizoma, Coptidis Rhizoma, Scutellariae Radix, and other botanical components. It is prepared as a ready-to-use aqueous solution with standardized extraction and quality control procedures. The mouthwash is administered as 10 mL per use, held in the oral cavity for 2-3 minutes, six times daily, starting from the first day of radiotherapy and continuing until the development of grade 3 or higher oral mucositis, as defined by the WHO or RTOG criteria. This intervention is distinguished from the placebo comparator by the presence of active herbal ingredients, and its appearance, color, taste, and packaging are matched by the placebo to enable double-blind conditions.

DRUG

Placebo Mouthwash

A placebo mouthwash formulated to match the active intervention (Modified Dahuang Huanglian Xiexin Mouthwash) in appearance, color, taste, and packaging. It contains no active pharmaceutical ingredients and is composed of purified water with pharmaceutical-grade coloring and flavoring agents to mimic the characteristics of the herbal formulation. The mouthwash is supplied as a ready-to-use aqueous solution. It is administered as 10 mL per use, held in the oral cavity for 2-3 minutes, six times daily, starting from the first day of radiotherapy and continuing throughout the radiotherapy course. This intervention is distinguished from the active comparator by the absence of active herbal ingredients and serves as a control to enable double-blind evaluation.
