ABSTRACT
A new nasal drug delivery system of diazepam has been developed with a natural mucoadhesive agent from Tamarindus indica L. The mucoadhesive strength, viscosity and gelling property of this natural mucoadhesive agent was found to be higher in comparison to synthetic polymers, hydroxy propyl methyl cellulose [HPMC] and carbopol 934 which are conventionally used for similar purpose. In vitro drug release characteristic through franz-diffusion cell using excised bovine nasal membrane was also found to be better in comparison to the above synthetic polymers. This patient friendly, needle free dosage form may replace the diazepam injections in future
