AIM

In the current study, efforts are being made to prepare Inhalable Silibinin loaded solid lipid nanoparticles (SLNs) with narrow size distribution with improved bioavailability.

METHODS

SLNs were formulated by high shear homogenisation method SLNs were characterised, including Differential Scanning Calorimetry (DSC), Fourier transform infra-red spectroscopy (FTIR), particle size analysis, entrapment efficiency with Aerodynamic behaviour. The MTT assay was performed against A549 cell line, to measure their anticancer cell activity with study.

RESULTS

Optimized formulation exhibited spherical surface with a mean particle size of 221±1.251nm, PI of 0.121± 0.081, zeta potential of -4.12±0.744. Aerodynamic behaviour such as Mass median aerodynamic diameter (MMAD) and Geometric size distribution (GSD) were found to be 5.487 ± 0.072 and 2.321 ± 0.141 respectively proved formulation is suitable for inhalation. cellular efficacy against A549 cells, revealed that the optimised formulations were more effective and potent.

CONCLUSION

The Inhalable SLNs approach was successfully engineered and administered to the lungs safely without causing any problems.
