Investigation of Corchorus olitorius mucilage as a potential mucoadhesive agent in developing in situ mucoadhesive nasal gel

The present study aimed to formulate a mucoadhesive in situ gel with mucilage extracted from Corchorus olitoriusfor the intranasal route. Propranolol HCl used as a model drug. For the comparative study, the mucoadhesive in situgels were prepared using two different concentration 0.4% and 0.5% of C. olitorius mucilage, Carbopol P-934 andhydroxypropyl methylcellulose. The prepared in situ gel was subjected to characterization test, such as pH, appearance,gelation temperature, spreadability, viscosity, mucoadhesive strength, and in vitro study. From the comparative study,0.5% mucilage containing in situ gel formulation can be considered as optimum formulation.
