*2.10. Stability*

An accurately weighed quantity of optimized SLN (CL10) was sealed separately in light resistant glass vials at ambient temperature (25 ± 1 ◦C) and under refrigerated conditions (4 ± 0.5 ◦C) up to 3 months [38]. The stability of SLN was examined by assessing the drug content, particle size, and drug release during the storage period.
