TLDR The developed nasal gel improves cilostazol delivery to the brain, enhancing its effectiveness and reducing side effects.
The study developed cilostazol-loaded spanlastics for nose-to-brain delivery to enhance cilostazol's solubility, absorption, and bioavailability while minimizing adverse effects. The formulations, incorporated into Phytagel®, Poloxamer-407, and chitosan gel bases, showed high encapsulation efficiency (>99%), suitable nasal droplet size, and improved cilostazol flux and permeability in vitro. The drug-release study indicated nearly complete release within 2 hours, suggesting improved bioavailability for cerebrovascular treatment. The optimal formulation, CIL-SPA1, demonstrated a Z-average suitable for brain targeting, high stability, and effective mucoadhesion, highlighting its potential for efficient central nervous system drug delivery.
