TECHNIQUES FOR SOLUBILITY ENHANCEMENT There are various techniques available to improve the solubility of poorly soluble drugs. For example, complexation of morin, a flavonol herbal medicine, with phospholipid increased its solubility in water from 18 μg/ml to 74 μg/ml and in n-octanol from 12 mg/ml to over 1000 mg/ml, but the complexation resulted in over 5-fold increase in the oral bioavailability of morin in rats (Zhang et al., 2011). Keywords: Solubility, solubility enhancement, co … INTRODUCTION: As a most discussed but still not completely resolved issue, solubility or dissolution enhancement techniques remain a most vibrant field for the researchers in formulation science.Solubility and dissolution are the core concepts of any physical or chemical science including biopharmaceutical and pharmacokinetic considerations in therapy of any medicine. Techniques of Solubility Enhancement: There are various techniques available to enhance the solubility of poorly soluble drugs. Following literature reports about the enhancement of solubility and stability for these kinds of drugs upon complexation with cyclodextrins, we aimed to form an inclusion complex between temozolomide and the different types of cyclodextrins (CDs) to enhance its solubility. Enhancement of solubility of TMZ. The purpose of this review article is to describe the techniques of solubilizaton for the attainment of effective absorption and improved bioavailability. In order to investigate if TMZ-CD complexation enhances solubility of TMZ, after mixing, the solution was shaken at 300 rpm for 24 hours at 37 o C. The undissolved TMZ was removed by centrifuging at 6000 rpm for 5 minutes. ALTERATION IN pH OF THE SOLVENT SYSTEM 2.
