癌化学療法時の口腔粘膜障害予防を目的としたメシル酸カモスタットトローチ剤の開発

We prepared a troche containing camostat mesilate for the prevention of the mucositis in the mouth induced by cancer chemotherapy. The troche was formed by the direct compression of a powder mixture of camostat mesilate, a flavoring agent, hydroxypropylcellulose, and magnesium stearate. A troche containing 10% or 20% hydroxypropylcellulose and a flavoring agent of coffee or green apple diminished the bitterness of camostat mesilate. It was found that the metabolising rate of camostat in saliva was much slower than that in blood, although metabolites in saliva were the same kinds as those in blood. The amounts of camostat retained in the mouth after administration of the troche to healthy subjects were much larger than those after applying a gargle which had a bitter taste. Moreover, the troche containing the flavoring agent of green apple showed smaller amounts of camostat and its metabolites retained in the mouth compared to the troche containing the flavoring agent of coffee. It is considered that the increase in the secreting volume of saliva after administration of the troche containing the flavoring agent of green apple would prevent the retaining of camostat and its metabolites in the mouth. Moreover, the administration of a troche is more convenient than that of a gargle for patients. The troche prepared in this study would be a substitute dosage form for the gargle and promote the quality of life in patients.
