Abstract

The invention belongs to the field of medicine and particularly relates to a transdermal preparation for treating oral mucositis caused by radiotherapy of tumor. The transdermal preparation comprisesactive ingredients of 109-237 parts by weight of amifostine and 42-85 parts by weight of uridine triacetate. The transdermal preparation is administered externally at a daily dose level of milligrams,has a markedly improved effect on the oral mucositis caused by the radiotherapy, and can avoid the drop of blood pressure caused by large doses of amifostine hydrochloride to affect the health of patients with normal blood pressure or hypotension.

Description

technical field [0001] The invention belongs to the field of medicine, and in particular relates to a transdermal drug delivery preparation for treating oral mucositis caused by tumor radiotherapy. Background technique [0002] Nasopharyngeal carcinoma is a malignant tumor that occurs in the mucosal epithelium of the nasopharynx. The most common location is the top of the nasopharyngeal roof and posterior wall, followed by the side wall, and the anterior and bottom walls are extremely rare. The incidence rate of this disease is low in other countries in the world, but the incidence rate in my country is significantly higher than other countries. Its epidemiological reasons are currently unknown. According to epidemiological statistics, patients with NPC in my country account for more than 80% of the total number of NPC patients in the world. Among them, there are also significant regional differences in the regional distribution of nasopharyngeal carcinoma patients in my c...
