Drug Nano-Particles Formation by Supercritical Rapid Expansion Method; Operational Condition Effects Investigation
Dissolution pressure and nozzle temperature effects on particle size and distribution were investigated for RESS (Rapid Expansion of Supercritical Solution) process. Supercritical CO2 was used as solvent and Ibuprofen was applied as the model component in all runs. The resulting Ibuprofen nano-particles (about 50 nm in optimized runs) were analyzed by SEM and laser diffraction pa...

متن کاملMicronization of magnolia bark extract with enhanced dissolution behavior by rapid expansion of supercritical solution.
A rapid expansion of supercritical solution (RESS) technology was presented for the micronization of Chinese medicinal material. Magnolia bark extract (MBE) obtained by supercritical carbon dioxide (scCO(2)) extraction technology was chosen as the experimental material. RESS process produced 4.7 microm size MBE microparticles (size distribution, 0.2-24.1 microm), which was significantly smaller...
متن کاملFormation and Characterization of Beclomethasone Dipropionate Nanoparticles Using Rapid Expansion of Supercritical Solution.
PURPOSE Particle size of Beclometasone Dipropionate (BDP) was reduced by the rapid expansion of supercritical solution (RESS) process, using CO2 as supercritical solvent. Also, the effect of RESS parameters such as extraction pressure, pre-expansion temperature, and weight fraction of co-solvent on the size and distribution of BDP particles were investigated. METHODS The effects of extraction...
متن کاملModeling and Simulation of Rapid Expansion of Supercritical Solutions
Rapid expansion of supercritical solution (RESS) is a promising technique for microparticle production. The literature points out that the RESS technique can be applied to process a wide range of materials including ceramics, polymers, biopolymers, pharmaceutics, and organic compounds. In order to achieve an adequate understanding of the RESS process, it is necessary to conduct more comprehensi...
