Compritol?-based solid lipid nanoparticles of desvenlafaxine prepared by ultrasonication-assisted hot-melt encapsulation to modify its release
NANOMEDICINE(2024)
摘要
Aims: Desvenlafaxine (DES) in conventional dosage forms shows initial burst release after oral administration, leading to exaggeration of its side effects. These side effects can be overcome by a sustained-release dosage form using the chemically inert, low-melting-point lipid Compritol (R) 888 ATO, as it reduces initial burst release. Materials & methods: The potential of DES-loaded solid lipid nanoparticles (DES-SLNs) synthesized by ultrasonication-assisted hot-melt encapsulation to modify the release of DES was investigated. Results: The entrapment efficiency of DES-SLNs was 65.90% with the in vitro release profile showing a sustained-release behavior achieving 81% cumulative release within 16 h without initial burst release. Conclusion: DES-SLNs are a potential carrier for sustained release of water-soluble antidepressant drugs such as DES.
