Eleonora Maretti, Federica Gioia, Cecilia Rustichelli, Susanna Molinari, Eliana Leo. Molecules. 2024 Apr 3;29(7):1616.

Laboratory studyOther animals

Design
Laboratory study
Subjects
MH-S mouse alveolar macrophage cell line; no animals or people
Dose used in the study
Lipid nanoparticles made from palmitoylethanolamide, tested on cells up to 0.64 mg/mL
Duration
Not stated in the abstract
What was measured
Particle size and shape, PEA solubility, aerosol performance of freeze-dried powders, cell toxicity and uptake by macrophages.

What the authors reported

The study found:

  • PEA nanoparticles were about 250 nm, rounded, and much more soluble than raw PEA.
  • More mannose as cryoprotectant improved the emitted dose and fine particle fraction in an aerosol test.
  • The particles were not toxic to MH-S macrophages up to 0.64 mg/mL and were taken up rapidly by the cells.

Limits of this study

A formulation and cell study only; it cannot show effect in people or animals. No inhaled dosing in a living organism and no disease model. The authors declare no conflicts of interest.
