Response Surface Optimization, Fabrication and In-vitro Investigation of Elastic Nanovesicles Loaded with Flunarizine

The successful preparation of Flunarizine-loaded spanlastic nanovesicles using ethanol injection method significantly improved the drug's solubility. Flunarizine spanlastic formulations made up of Span 60 and EAs (Tween 40 and SDC) were prepared using various weight ratios of Span 60: EA. The study presented a viable and successful method for nasal delivery of the medication for migraine treatment.
