Exploring the Role of Self-Nanoemulsifying Systems in Drug Delivery: Challenges, Issues, Applications and Recent Advances

Ravinder Verma et al. Curr Drug Deliv. 2023.

Abstract

Nanotechnology has attracted researchers around the globe owing to the small size and targeting properties of the drug delivery vectors. The interest in self-nanoemulsifying drug delivery systems (SNEDDS) has shown an exponential increase from the formulator's point of view. SNEDDS have shown wide applicability in terms of controlled and targeted delivery of various types of drugs. They chemically consist of oil, surfactants and co-surfactants that decrease the emulsion particle size to the range of <100 nm. However, stability issues such as drug precipitation during storage, incompatibility of ingredients in shell, decrease their application for the long run and these issues have been highlighted in this paper. The current review throws limelight on the biological aspects and process parameters. In addition, the process of absorption from GI is also discussed in detail. SNEDDS have been utilized as a treatment option for various diseases like cancer, diabetes, and ocular and pulmonary diseases. Along with this, the authors highlight the advances involving in vivo and in vitro lipolysis studies on SNEDDS, also highlighting recent innovations in this field, such as novel combinations of drug-free solid SNEDDS + solid dispersions, lipid-modified chitosan containing mucoadhesive SNEDDS, pHsensitive SNEDDS and several others.

Keywords: Herbal SNEDDS; in vitro lipolysis; nanoemulsion; nanotechnology; optimization; pH-sensitive SNEDDS.
