Abstract
The chemical stability and the microbial numbers of non-sterilized and sterilized 0.1% allopurinol gargle (allopurinol gargle) were studied.Furthermore, studied the efficacy for some patients who were afflicted with oral mucositis.Allopurinol gargle (0.1%) was chemically stable under the storage in the room temperature or in the refrigerator at least for 15 days. Bacterial numbers in the non-sterilized samples increased at regular interval, while the sterilized sample wasn't detected the bacterial colonies for 15 days. On the therapeutical efficacy of allopurinol gargle for 8 patients, all 8 cases were judged effective.However, we think that more modification to the allopurinol gargle preparation and more clinical data would be needed.
