Allopurinol mouthwashes and 5-fluorouracil induced oral toxicity.Eur J Surg Oncol. 1985 Sep; 11(3):267-8.EJ
Allopurinol has been shown to decrease the gastro-intestinal and bone marrow toxicity of 5-fluorouracil. In an attempt to diminish mucositis resulting from 5-fluorouracil administration, whilst not affecting its systemic anti-tumour activity, an allopurinol mouthwash has been used. In six patients who experienced mucositis when treated initially with 5-fluorouracil, the use of an allopurinol mouthwash with subsequent courses resulted in a reduction of oral toxicity.
