RESUMEN
One of the drug delivery technologies is nanostructured lipid carriers (NLCs), which improve drug permeability and thus bioavailability. NLCs are nanoparticles made from a lipid matrix made up of a mixture of solid and liquid lipids. The inclusion of liquid lipids is useful in lowering the ordered structure of solid lipids, increasing nanoparticle loading capacity, and drug entrapment efficiency within NLCs. Hot homogenization, cold homogenization, micro-emulsion, emulsification-solvent diffusion, high shear homogenization, and/or ultrasonication techniques, double emulsion technique, melting dispersion method, membrane contractor technique, and evaporation solvent injection are some of the methods that can be used to make NLCs. Both hydrophilic and lipophilic medicines can be carried out by NLCs. They can deliver medications in a variety of ways, including oral, topical, transdermal, parenteral, and ophthalmic. During the process of preparing this review article, several distinct studies and patent reports about various methods of NLCs formulations, their various therapeutic applications, and various routes of administration were investigated and discussed. The study conducts an in-depth evaluation of the most recent research publications and patents. NLCs have been utilized to treat a variety of disorders, including cancer, fungal infections, bacterial infections, inflammation, liver diseases, and ocular infections, due to their benefits. They can deliver medications to specific locations throughout the body, allowing for drug targeting and a reduction in unwanted side effects. They can also be used to improve bioavailability, reduce the medication's supplied dose, and improve the drug's pharmacological activity.
