Nanostructured lipid carriers with ultra purified lipids for sustained release of intravenous lidocaine

Resumo

Lidocaine (LDC) is a local anesthetic that can be used for post-surgical or cancer related pain, via intravenous infusion or bolus. An alternative to maintain drug plasma levels are the sustained release carriers, whereas nanostructured lipid carriers (NLCs) stand out; they have biocompatibility, low toxicity, reproducibility and high efficiency in the transport of hydrophobic drugs.This work aims to study the solubility parameter of the LDC pre formulation in several ultra-purified lipids, compatible with the endovenous route, and to formulate NLCs based on these lipids for LDC encapsulation.
