Development and Evaluation of a Mucoadhesive Nasal Gel of Midazolam Prepared with Linum usitatissimum L. Seed Mucilage

Abstract
The aim of the present study was to prepare mucoadhesive nasal gels from mucilage isolated from seeds of Linum usitatissimum L. containing midazolam hydrochloride. Characterization of the isolated mucoadhesive agent was carried out, including determination of pH, swelling property, viscosity and mucoadhesive strength. The results were compared with synthetic polymers (HPMC and carbopol 934). Nasal gels of midazolam were prepared with and without enhancers and the permeation study was carried out using excised goat nasal mucosa. Permeation profiles were evaluated and histological study of nasal mucosae before and after permeation study was also conducted to determine histological change, if any.
