Effect of Arginine and Glutamine on Radiation-induced Oral Mucositis: a Trible Blinded Randomized Controlled Clinical Trial

Participants in this group will receive an oral suspension containing 5 grams of glutamine dissolved in cold water. This solution is administered 30 minutes before meals, three times per day, using the swish and swallow technique throughout the radiotherapy period. This control intervention serves to compare the effects of glutamine alone with the combined arginine and glutamine treatment. In addition to the glutamine suspension, patients in this group will receive general measures and analgesic drugs according to the WHO scale to manage symptoms of mucositis.

Participants in this group will receive an oral suspension containing 5 grams of arginine and 5 grams of glutamine dissolved in cold water. This solution is administered 30 minutes before meals, three times per day, using the swish and swallow technique throughout the radiotherapy period. The swish and swallow technique involves patients swishing the solution around the oral mucosa to ensure even distribution before swallowing. This intervention aims to evaluate the combined effect of arginine and glutamine on reducing the severity of radiation-induced mucositis, improving mucosal healing, and providing symptomatic relief.
