Author: Sandeep Kumar, Pritam Singh Abstract: Solubility is not to be confused with the ability to dissolve or liquefy a substance, since this process may occur not only because of dissolution but also because of a chemical reaction. There are various techniques for solubility enhancement. Request PDF | Solubility Enhancement Techniques | Solubility is the phenomenon of dissolution of solid in liquid phase to give a homogenous system. The poor solubility of drug substances in water (less than 1µg/ml) and their low dissolution rate in aqueous G.I.T fluid often leads to /FontWeight 400 /Name /F1 endobj Consequences of poor aqueous solubility would lead to failure in formulation development. 30 0 obj 3 0 obj Solubility And Dissolution Enhancement Of Bosentan Monohydrate By Solid Dispersion Technique Ravindra Bhanudas Saudagar Department of Pharmaceutical Chemistry, KCT’S RGS College of Pharmacy, Anjaneri, Nashik, Maharashtra, India Manoj Kailas Patil Department of Quality Assurance Techniques, R.
