- W2014453247 abstract "The poor solubility and low dissolution rate in gastro-intestinal fluid, especially for class-II drugs according to Biopharmaceutics Classification System (BCS) the bioavailability enhanced by increasing the solubility and dissolution rate. A novel melt sonocrystallization technique of particle engineering to enhance solubility as well as dissolution of hydrophobic drug and to study its effect on crystal properties of drug. The present study leads to use investigate solubility of melt sonocrystallization technique to modify the undesirable properties of Rosiglitazone is antidiabetic drug in thiozolidione category with (BCS II) to forms agglomerates with number of shallow circular pits on the surface leads to increase solubility. Melt sonocrystallization process was developed for Rosiglitazone in which Rosiglitazone melt was poured in deionized water and simultaneously subjected to ultrasonic energy for 20 min at amplitude 80 %. The product obtained was evaluated using scanning electron microscopy, differential scanning calorimetry, X-ray powder diffractometry (XPRD), Fourier transformed infrared spectroscopy (FTIR), solubility and dissolution rate. The irregular agglomerates with porous surface were obtained having different crystal habit which increases solubility and dissolution rate. FTIR shows thermal behavior of untreated Rosiglitazone and treated Rosiglitazone have no significant difference low intensity peaks in XPRD of treated Rosiglitazone were noticed crystals habit changes and lattice defects during processing have causes favorable changes in the physicochemical properties of Rosiglitazone. The use of melt sonocrystallization technique is promising technique that may affords powder with improved flow as well as improved solubility and dissolution. La scarsa solubilità e il basso tasso di dissoluzione nei liquidi gastro-intestinali, soprattutto per farmaci di classe II secondo il Biopharmaceutics Classification System (BCS) richiede, per la biodisponiblità, un aumentando della solubilità e velocità di dissoluzione. Valutiamo una nuova tecnica di ingegneria delle particelle di scioglimento per sonocristallizazione per migliorare la solubilità, nonché la dissoluzione del farmaco e il suo effetto sulle proprietà cristalline del farmaco. Il presente studio indaga quindi la tecnica di scioglimento per sonocristallizazione per modificare la solubilità e le proprietà indesiderabili del Rosiglitazone, farmaco antidiabetico della categoria dei thiozolidione (BCS II) con la formazione di depressioni circolari poco profonde sulla superficie, per aumentare la solubilità. Il processo di scioglimento per sonocristallizazione è stato sviluppato per il Rosiglitazone. In questo esperimento il Rosiglitazone è stato versato in acqua deionizzata e contemporaneamente sottoposto a energia ad ultrasuoni per 20 min. con ampiezza all’ 80 %. Il prodotto ottenuto è stato valutato mediante microscopia elettronica a scansione (SEM), calorimetria differenziale a scansione (DSC), raggi X a diffrazione (XPRD), trasformata di Fourier con spettroscopia ad infrarossi (FTIR), solubilità e velocità di dissoluzione. Sono stati ottenuti agglomerati irregolari, con superficie porosa con diverso aspetto cristallino, che aumenta la solubilità e di dissoluzione. La FTIR mostra un comportamento termico del Rosiglitazone non trattato e trattato senza alcuna differenza significativa, picchi di bassa intensità del Rosiglitazone trattato sono stati notati in XPRD con cambiamenti cambiamenti favorevoli delle proprietà fisico-chimiche del Rosiglitazone. L’uso della tecnica scioglimento con sonocristallizazione è una tecnica promettente un migliore flusso e migliore solubilità e dissoluzione." @default.
