To evaluate the efficacy of Ethosomes encapsulated with 5-FU in treatment of laryngotracheal stenosis in rabbit models.The 5-FU ethosome was prepared by the thin film hydration method, and the size distribution and the encapsulation efficiency was investigated. The tracheal mucosa was scraped about 0.5 cm in width with a nylon brush to induce the scar formation in the airway,then animals were divided into three groups: 5-FU ethosome group,5-FU group and saline group. Drugs were injected into scar by paracentesis under endoscope in each group respectively. The severity of stenosis was observed under laryngofiberoscope immediately, 7, 14, 21 days after administration.Airway stenosis of 5-FU ethosome group was not significantly different compared with 5-FU group at 7 days after administration, but 5-FU ethosome significantly reduced the airway stenosis at 21 days after administration when compared with 5-FU group and no restenosis was noticed during the observation period.Ethosomes encapsulated with 5-FU was effective for laryngotracheal stenosis. It is a potentially new method for ameliorating airway stenosis originated from granulation tissue. |
