Concentration of Itraconazole Solution in Nasal Secretions

• Status: Completed
• Trial end date: 2013-12-01
• Target enrollment: 0
• Participant gender: All

Summary

The primary objective of this study is to determine the concentration of itraconazole irrigation in nasal mucous specimens via collection and High-performance liquid chromatography (HPLC) assay.

Eight (8) patients with chronic rhinosinusitis (CRS) and two (2) healthy controls will be enrolled in the initial evaluation. After an initial control nasal specimen, followed by seven days of twice daily topical itraconazole irrigation, nasal specimens will be collected at varying time intervals and the concentrations measured.

The primary endpoint is development of a reliable collection and assay technique with concentration curves over time of topically administered itraconazole. A secondary endpoint is to determine if the concentrations measured achieve a mean inhibitory concentration (MIC90) to commonly cultured fungal species in the nose.
