Add mL of a solution containing mg /mL lecithin in methylene chloride, forming an emulsion. The methylene chloride is eliminated under vacuum at about°C. The biorelevant dissolution media have been updated recently to bring the composition and characteristics closer to those of aspirates collected from the human 'Biorelevant Dissolution Media' published in 'The ADME Encyclopedia' According to Eq, the rate of dissolution (dQ/dt) of a solid drug can be estimated as the product of the surface area of the solid (S), the diffusion coefficient (D), and the driving force of the dissolution (i.e., the difference between C s and C, the concentration within the solution, at a given time) divided by the Dissolution behavior oftwo class Idrugs, i.e. The amount of drug substance is based on the compound potency and projected human With the array of compendial and physiological media available, it should be possible to design a suitable set of tests to predict the in vivo dissolution of both class I and II Preparation of FaSSIF. dana2ol, mefenamic readily in aqueous media over thepHrange 1toSince acid and ketoconazole, w studied with USP Apparatus 2in water.
