Compositions comprising amino acids for use in the treatment of mucositides in neoplasia patients undergoing radiation therapy and/or chemotherapy

A method of treating mucositis in a patient who is suffering from neoplasia of the cervical-cephalic region and who is undergoing radiation therapy and/or chemoradiotherapy, the method consists of:

• (1) selecting an amino acid composition for use in the treatment of mucositis in the patient who is suffering from neoplasia of the cervical-cephalic region and who is undergoing radiation therapy and/or chemoradiotherapy, the amino acid composition consists of:
• (i) an active agent, said active agent consists of the amino acids glutamine, leucine, isoleucine, valine, lysine, threonine, histidine, phenylalanine, methionine, tryptophan, tyrosine, and cystine, wherein
• (a) the amino acid composition is free of any further different amino acids,
• (b) the glutamine:leucine weight ratio is in the range 4.3 to 5.3, and
• (c) glutamine is present in an amount between 50 and 65% by weight with respect to the total weight of the active agent, and
• (ii) optionally at least one of, none of which have any amino acids:
• carbohydrates, at least one thickening agent, at least one vitamin, pharmaceutically acceptable excipients, and flavouring substances, and
• (2) administering the amino acid composition to the patient to treat mucositis in the patient who is suffering from neoplasia of the cervical-cephalic region and who is undergoing radiation therapy and/or chemoradiotherapy.
