Abstract
Background: The objective of this study was to investigate the potential of niosomal gels as a transdermal delivery system to improve the permeation and anti-inflammatory activity of Lornoxicam (LX).
Methods: LX niosomes were prepared by thin film hydration technique and were characterized using Transmission Electron Microscopy (TEM), Differential Scanning Calorimetry (DSC), Particle Size analysis and Zeta potential determination. LX niosomal gel/LX loaded gel were prepared using Carbopol 934 (2%) and were evaluated for their physical appearance, pH and rheological behaviour. Ex vivo skin permeation test was performed on dorsal region of wistar rats. In vivo studies comprised skin irritation test and anti-inflammatory activity study.
Results: The prepared LX niosomes exhibited an entrapment efficiency of more than 66% and a particle size diameter ranging from 295 nm to 1298 nm, with negatively charged zeta potential. TEM electron micrographs revealed spherical shaped vesicles. The release pattern of drug was analyzed and found to follow Higuchi's model. Rheology studies revealed the pseudoplastic behaviour of LX niosomal gel. They exhibited a one and half fold increase in drug permeated through rat skin, when compared to free drug. Skin irritation test proved the non-irritancy of LX niosomal gels, when applied to dorsal region of Wistar rats. Percentage edema inhibition of LX niosomes was significantly higher (P<0.05) than that of free LX group showing an enhanced anti-inflammatory activity of LX niosomes.
Conclusion: These findings revealed that LX loaded niosomal gels could be a potential transdermal drug delivery system.

Emerging Nanotherapeutics for Mitigation of Neurodegenerative Disorders
Conditions affecting the central nervous system (CNS) present a significant hurdle due to limited access of both treatments and diagnostic tools for the brain. The blood-brain barrier (BBB) acts as a barrier, restricting the passage of molecules from the bloodstream into the brain. The most formidable challenge facing scientists is ...read more
Nanotechnology Based Chemotherapy for the treatment of Head & Neck Cancer
The escalating recurrence rates observed in Head and Neck cancer, particularly within the chemo-therapeutically treated cohort (50-60%), can be attributed to the non-selective nature of current anticancer drug delivery modalities. In this context, nanotechnology-based drug delivery systems emerge as a promising avenue for achieving precise localization of therapeutic agents to ...read more
