Abstract
Abstract: Introduction: Nasal route is an alluring route for direct drug delivery to the central nervous system (CNS), owing to its avoidance of the hepatic first-pass metabolism and deciphering the blood–brain barrier passage issues. ROP-HCl has a lower experimental BBB permeability therefore ROP-HCl freighted niosomes were fabricated by ethanol injection method and served two purposes one being a novel Niosomal formulation impacting the permeability and other obtaining a sustained release property which likely would lead to an improved bioavailability of ROP-HCl. Objectives: The present study is aimed to develop a stable non-ionic surfactant vesicle; Niosomes embodying Ropinarole Hydrochloride (ROP-HCl) for ameliorated treatment of Parkinson’s disease (PD) by statistical optimization employing a 3-level factorial design using Design Expert® software. Materials and Methods: All the formulations were characterized physiochemically and morphologically. Additionally, the drug and excipients interaction studies were evaluated using Differential scanning calorimetry (DSC), X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR). Further, in vitro release kinetics using DD solver excel add-in and mechanism was studied for developed Niosomal formulation. Cytotoxicity study was studied in Raw 264.7 cells. in a concentration dependent manner and ex vivo, permeability was done using sheep mucosa. Toxicity was studied by histological examination. Results: The IC50 value of developed Niosomes was lower than drug itself and further the permeability of developed Niosomes was considerably enhanced compared to ROP-HCl alone. Histological examination revealed safe nature of developed formulation. Conclusion: These results conveyed that, Niosomes can be a valuable carrier for the nasal delivery of ROP-HCl to CNS. Keywords: Ropinirole hydrochloride, Statistical approach, Niosomes, Nasal drug delivery, cytotoxicity, Release kinetics, Ex-vivo permeability, Toxicity study.
