Abstract

The purpose of the present investigation was to prepare and evaluate formulations of safranal to improve solubility, stability and facilitate the blood brain barrier crossing of the drug. Niosomes are prepared using various surfactants in different ratios with cholesterol, and optimized based on vesicle size, drug entrapment, drug release and effect of sonication. Then to increase resident time of formulation in the nasal cavity optimized niosomal formulation (B1) further formulated in to in-situ nasal gel using surface response factorial Method. Concentration of Pluronic F-127 and gelrite were used independent variables as the polymers exhibited the phase transition behaviour and gelation temperature and gelation pH was used as dependent variable. The optimised gel concentration (pluronic F127: gelrite,(17.3:0.07) was then used to formulate the in situ niosomal nasal gel The prepared formulation was then characterized for drug loading, content uniformity, in‐vitro drug diffusion, mucoadhesive strength, gel strength, viscosity and gelation temperature. The formulation so prepared was in the liquid state at room temperature while turned into a gel at the pH and temperature of the nasal cavity. Formulation showed the increased bioavailability of drug in in-vivo experiments.
