New methods for lipid nanoparticles preparation

Area of Science:

• Nanotechnology and Pharmaceutical Sciences
• Drug Delivery Systems

Background:

• Lipid nanoparticles (LNPs) are increasingly favored over liposomes and polymeric nanoparticles due to superior tolerability.
• High-pressure homogenization, a common method for solid lipid nanoparticle (SLN) preparation, has critical process parameters and patent limitations.

Purpose of the Study:

• To review novel methods for lipid nanoparticle preparation.
• To explore recent pharmaceutical applications of these advanced lipid nanoparticle techniques.
• To address limitations and patent issues associated with traditional SLN production.

Main Methods:

• Review of recent literature and patents on lipid nanoparticle preparation.
• Focus on alternative techniques including coacervation, microemulsion templates, supercritical fluid technology, and phase-inversion temperature (PIT) methods.

Main Results:

• Identification of several innovative lipid nanoparticle production techniques.
• Discussion of the advantages and challenges of each reviewed method.
• Highlighting the growing research interest in diverse LNP preparation strategies.

Conclusions:

• New lipid nanoparticle preparation techniques offer promising alternatives to established methods like high-pressure homogenization.
• These advanced methods provide opportunities for overcoming production challenges and expanding pharmaceutical applications of LNPs.
• Continued research into these novel techniques is crucial for advancing drug delivery systems.
