Formulation and Evaluation of Fluvoxamine Maleate Loaded Lipid Nanoparticle

Recently solid lipid nanoparticles (SLN's) have been received much attention by the researchers owing to its biodegradability, bioavailability and the ability to deliver wide range of drugs to the targeted site of action. The purpose of the present study is to develop and evaluate the fluvoxamine maleate loaded lipid nanoparticles. The fluvoxamine maleate lipid nanoparticles (LN’s) were prepared by the hot melt homogenization followed by the sonication by using different combination of lipids like tristearin, compritol, olive oil, coconut oil, sesame oil. Compatibility study was confirmed by FTIR and DSC. The LN’s were evaluated for particle size, PDI, zeta potential, entrapment efficiency and in-vitro drug release. For the Fluvoxamine maleate LN’s prepared using the solid lipids, the particle size ranged from 98.58 to 152.43 nm. PDI of all formulations were good within the range of 0.239 to 0.456 with zeta potential from - 6.52 to -18.6 mV. Entrapment efficiency observed was in the range of 64.56 to 84.23 %. The cumulative percentage release of fluvoxamine maleate from different LN’s varied from 46.14 to 81.48%. For the formulations prepared using the combination of solid lipids and liquid lipids, Fluvoxamine maleate LN’s the particle size ranged from 63.22 to 263.8 nm. With good PDI range from 0.229 to 0.514 Zeta potential of all formulation is from - 5.01 to -9.30 mV. Entrapment efficiency observed was in the range of 71.02 to 90.51 %. The cumulative percentage release of fluvoxamine maleate from different LN’s varied from 63.71 to 85.41% depending upon the drug lipid ratio, the type of lipid used. The release kinetic studies showed that the release was first order, diffusion controlled, and the ‘n’ values obtained from the Korsmeyer-Peppa’s model indicated the release mechanism was Anomalous (non-Fickian) diffusion type.
