Solid Lipid Nanoparticles and Nanostructured Lipid Carriers of Loratadine for Topical Application: Physicochemical Stability and Drug Penetration through Rat Skin

Abstract: Purpose: To prepare solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC) of loratadine (LRT) for the treatment of allergic skin reactions. (> 90.67 %). LRT was compatible with the other excipients after 6 months. Particle size did not significantly alter particularly at RT. The highest release rate was obtained with NE (1.339 ± 0.026 mcg/ml/h) followed by NLC (1.007 ± 0.011 mcg/ml/h) and SLN (0.821 ± 0.012 mcg/ml/h), indicating anomalous transport (p < 0.05). Penetration profiles of LRT thr… Show more

“…Since the value of release exponent (n) for the proposed model was found to be 0.56, it implies that optimized NLC formulation follows Anomalous Diffusion (both diffusion and erosion) pattern (0.5 < n < l). The same release kinetics pattern for NLC for topical delivery of nitrendipine and piroxicam was described by previous researchers (Monica et al 2014, Uner et al 2014.…”

“…Solid and liquid lipid is melted and dispersed in an aqueous surfactant solution under high shear homogenization or ultrasonication resulting in formation of nanodispersion. 33,34 Intense shear forces necessary for the nano-emulsification are generated by ultrasonic cavitation which produces violently and asymmetrically imploding vacuum bubbles and break up particles down to the nanometer scale. 35 Probe-type ultrasonication produce desired effects like homogenization, dispersion, deagglomeration, milling and emulsification.…”

“…Nanoparticles' ability to treat tumors has been extensively investigated by different scholars (Paciotti et al, 2004;Chen et al, 2016) Solid lipid nanoparticles are colloidal particles, consisting lipid materials, which are stabilized with the use of varying types of surfactants and cosurfactants. Their use is mainly in topical route (Ü ner et al, 2014;Samein 2014). SLN are received readily by the skin due to its hydrophobic nature, enabling the encapsulation of the hydrophobic drugs with ease (Sanap & Mohanta, 2014).…”
