Summary
This study presents a continuous, scalable method for producing solid lipid nanoparticles (SLN) using static mixers. The process controls particle size and allows for drug loading, demonstrating potential for large-scale SLN manufacturing.
Area of Science:
- Pharmaceutical Technology
- Materials Science
- Chemical Engineering
Background:
- Solid lipid nanoparticles (SLN) are crucial drug delivery systems.
- Current SLN synthesis methods often face challenges in scalability and continuous production.
Purpose of the Study:
- To develop a continuous and scalable nanoprecipitation method for SLN synthesis.
- To investigate the influence of process parameters on SLN characteristics.
- To demonstrate drug loading into the synthesized SLN.
Main Methods:
- Utilized static mixers for continuous nanoprecipitation by mixing lipid acetonic solutions with water.
- Investigated process parameters including lipid concentration and flow rate.
- Evaluated particle size, size distribution, and drug loading efficiency.
Main Results:
- Achieved continuous production of SLN below 200 nm with high throughput (37.5-150 g/h).
- Demonstrated that higher lipid concentration leads to larger SLN.
- Successfully loaded fenofibrate, a model drug, into the SLN.
Conclusions:
- Static mixing-nanoprecipitation is a viable technique for continuous and large-scale SLN production.
- The developed platform offers control over SLN size and enables drug encapsulation.
- This method holds significant potential for pharmaceutical manufacturing.
