Modasiya 1 1, APMC College of Pharmaceutical Education and Research, Himatnagar, (Gujarat) - India solubility of many drugs that are practically insoluble in water, along with incorporation of proteins for oral, Volume 5, Issue 1, November – December 2010; Article-007 ISSN 0976 – 044X Methods for measurement of solubility and dissolution rate of sparingly soluble drugs 5 1 Introduction The dissolution rate and the release rate of a drug are essential to know for drug characterization. In order to measure the Lamivudine shows highest solubility in 0.01 N HCl where The combined effect of ionization and complexation on drug solubility has been derived similarly to the above scenario of solubilization by ionization and micellization. Abstract Methods are described for detecting precipitation of ionisable drugs under conditions of changing pH, estimating kinetic solubility from the onset of precipitation, and measuring solubilit...

A cosolvency model to predict the solubility of drugs at several temperatures was derived from the excess free energy model of Williams and Amidon.
