ZHANG Lijuan, LONG Chunxia, QIAN Yu, et al. Stabilizer distribution on surface of solid lipid microparticles and SLM stability: mesoscale simulation and experiments[J]. CIESC Journal, 2007, (1).DOI:
Dissipative particle dynamics (DPD) simulation was used to model the distribution of stabilizers (lecithin
poroxamer and PVA)on the surface of ibuprofen-loaded solid lipid microparticles (SLM).It was shown from DPD simulation results that lecithin totally enwrapped the surface of SLM when the molar fraction of ibuprofen was 1% and 2%.However
when the molar fraction of ibuprofen was increased to 3% and 5%
lecithin could not cover the place with a higher concentration of ibuprofen molecules.Poloxamer 407 and PVA totally enwrapped the surface of SLM when the molar fraction of ibuprofen was increased from 1% to 5%.The experimental results could be interpreted with the simulation results.DPD simulation provides an insight into the microstructure of a drug carrier and helps to analyze the experimental results
