Lipid nanoparticle topical & transdermal delivery: a review on production, penetration mechanism to skin

Abstract

Lipid nanoparticles are an alternative and modern carrier system to traditional drug delivery system i.e. liposomes and emulsions. This systematic review on lipid nanoparticles focus on production, challenges and advancement of delivery of drug via topical and transdermal route. Production of solid lipid nanoparticles and naostructured lipd carrier are produced by a variety of technique which explored in current review. Lipid nanoparticle exhibit many features for topical application of cosmetics and pharmaceutics, i.e. controlled release of actives, Physical and chemical stability of active pharmaceutical ingredients, drug targeting, occlusion, film formation and associated with it penetration enhancement and increase of skin hydration. Due to the production of lipid nanoparticles from physiological and/or biodegradable lipids, this carrier system exhibits an excellent tolerability. Furthermore an overview of the benefit/risk ratio of lipid nanoparticles also explored in this paper. The SLN & NLC are a “nanosafe” carrier for the delivery of active pharmaceutical via topical route.
