Design, Development and Evaluation of Dexamethasone Sodium Phosphate Niosomal in-situ Gel for Visual Medication Conveyance

Abstract

The main purpose of this study was to beat issues related with lachrymal seepage by eye drops, obscured vision with semi solid formulation, distinctive framework was joined together as niosomes and in-situ gel by fusing niosomes in-situ gel formulation, so it is anything but difficult to controlled and hold at the site for drag out timeframe. The Dexamethasone sodium phosphate, a glucocorticosteroid anti-inflammatory drug utilized as a part of treatment of eye hypersensitive condition, keratitis, after eye surgery, post cataract treatment. Niosomes containing Dexamethasone sodium phosphate definitions were prepared by solvent injection technique using cholesterol alongside different surfactants proportions. Prepared Niosomal preparations were fused in-situ gel formulation plan by scattering the Niosomes in solution of carbomer 974 P (0.2-0.6% w/v) and Hydroxypropyl-methylcellulose (HPMC) K4M (0.5-0.8% w/v). Prepared formulations were assessed for their vesicle measure, entanglement proficiency, in-vitro sedate discharge, thickness, in-vitro gelation study and so on. From the results it can be concluded that by utilizing cholesterol: Tween-80 (1:2) proportion, particle size of Niosomes was B4 was 368.7 nm with 93.15% drug entrapment efficiency. In-vitro drug release kinetics from Niosomal in-situ gel definition demonstrates that 98.42% drug release in 6 hrs with the utilization of 0.8% w/v of HPMC K4M and 0.6% w/v of Carbomer 974 P. In conclusion, the Niosomal in-situ gel is a practical contrasting option to routine eye drops due to excellence of its capacity to improve bioavailability through its more drawn out residence time and capacity to sustain the drug release.
