MICROENCAPSULATION BY SOLVENT EVAPORATION METHOD OF BCS CLASS 4 DRUGS FOR BIOAVAILABILITY ENHANCEMENT

Studies on Enhancement of Solubility and Bioavailability of Bcs Class Ii/iv Drugs

Silica-Lipid Hybrid Microparticles for Improved Bioavailability of Bcs Class IV Drugs

The main objective of the current review is to cover the overview of silica lipid hybrid microparticles. Lipid-based delivery systems recognized as a potential strategy for improving the oral absorption. Clinical applications of many lipid-based formulations are limited by the lack of clear guidelines of incomplete understanding of absorption mechanism and in vitro, in vivo formulation performa...

Microencapsulation by solvent extraction/evaporation: reviewing the state of the art of microsphere preparation process technology.

The therapeutic benefit of microencapsulated drugs and vaccines brought forth the need to prepare such particles in larger quantities and in sufficient quality suitable for clinical trials and commercialisation. Very commonly, microencapsulation processes are based on the principle of so-called "solvent extraction/evaporation". While initial lab-scale experiments are frequently performed in sim...

Preparation of Eudragit E100 microspheres by modified solvent evaporation method.

The objective of this investigation was to develop the hollow microspheres as a new dosage form of floating drug delivery system with prolonged stomach retention time. Hollow microspheres containing ranitidine hydrochloride were prepared by solvent evaporation method using Eudragit RLPO dissolved in a mixture of dichloromethane and ethanol. The maximum yield and drug loading amount of hollow mi...

Enhancement of dissolution profile for oral delivery of Fexofenadine Hydrochloride by solid dispersion (solvent evaporation) technique

The objective of present work is to investigate the enhancement of dissolution profile for oral delivery of Fexofenadine Hydrochloride (FH) through solid dispersion (SD) technique by the method of solvent evaporation. The SD was prepared by using ethanol as a solvent. Tablets were formulated containing solid dispersion of FH and compared with tablets of same formula without solid dispersion of ...
