Book Description
Use of colloidal carriers in drug delivery continues to grow. This created a need in the pharmaceutical field for better understanding of the physical and physicochemical properties of such, often complex, colloidal systems. This dissertation aims at improving this understanding and at developing simple characterization techniques to assist in colloidal drug carrier development. Chapter 1 provides a short introduction. In Chapter 2 I introduce and explain a new analytical approach to analyzing potentiometric data measured with lipid vesicle suspensions. The proposed model for the first time properly considers the Coulombic electrostatic interaction in addition to the hydrophobic interactions underlying drug-carrier association. Chapter 3 revisits vesicle-to-micelle transformation in phosphatidylcholine-cholate mixtures, and pays special attention to the lipid bilayer curvature effects. The emerging picture of the studied vesicle-to-micelle transformation is richer, but also more complex, than previously known. In Chapter 4 I investigate the applicability of UV/Vis spectrometry to characterization of submicroscopic drug carriers, such as lipid vesicles. The results suggest that the measured turbidity spectra contain sufficient information for accurate, fast, and viscosity-independent characterization of submicroscopic drug carriers. The advanced analytical approaches developed and investigated in this dissertation lend themselves to applications in pharmaceutical research and quality control, but also more generally in colloidal carriers characterization.

Book Description
The field of solid state characterization is central to the pharmaceutical industry, as drug products are, in an overwhelming number of cases, produced as solid materials. Selection of the optimum solid form is a critical aspect of the development of pharmaceutical compounds, due to their ability to exist in more than one form or crystal structure (polymorphism). These polymorphs exhibit different physical properties which can affect their biopharmaceutical properties. This book provides an up-to-date review of the current techniques used to characterize pharmaceutical solids. Ensuring balanced, practical coverage with industrial relevance, it covers a range of key applications in the field. The following topics are included: Physical properties and processes Thermodynamics Intellectual guidance X-ray diffraction Spectroscopy Microscopy Particle sizing Mechanical properties Vapour sorption Thermal analysis & Calorimetry Polymorph prediction Form selection

Book Description
The aim of this book is to present a range of analytical methods that can be used in formulation design and development and focus on how these systems can be applied to understand formulation components and the dosage form these build. To effectively design and exploit drug delivery systems, the underlying characteristic of a dosage form must be understood--from the characteristics of the individual formulation components, to how they act and interact within the formulation, and finally, to how this formulation responds in different biological environments. To achieve this, there is a wide range of analytical techniques that can be adopted to understand and elucidate the mechanics of drug delivery and drug formulation. Such methods include e.g. spectroscopic analysis, diffractometric analysis, thermal investigations, surface analytical techniques, particle size analysis, rheological techniques, methods to characterize drug stability and release, and biological analysis in appropriate cell and animal models. Whilst each of these methods can encompass a full research area in their own right, formulation scientists must be able to effectively apply these methods to the delivery system they are considering. The information in this book is designed to support researchers in their ability to fully characterize and analyze a range of delivery systems, using an appropriate selection of analytical techniques. Due to its consideration of regulatory approval, this book will also be suitable for industrial researchers both at early stage up to pre-clinical research.

Book Description
What are the physical and chemical properties that determine how a drug interacts with the body? What determines which dosage form is best, if it will reach its intended target, and how it will be metabolised once it has entered the body? The Physicochemical Basis of Pharmaceuticals explores the phenomena which affect the formulation and bio-availability of drug substances to give a straightforward, accessible treatment of the essential concepts affecting the absorption and distribution of drugs. It provides the reader with the conceptual 'tool-kit' necessary to understand the physicochemical aspects of drug design and action, and shows how these concepts apply in practice. The book introduces key underlying physical chemistry principles before exploring pharmaceutical solutions, the pharmaceutical solid phase, solid - liquid dispersal systems, biological interfaces, absorption, distribution, metabolism and excretion, to give a complete view of the field. Focusing at all times on the essential principles and concepts, The Physicochemical Basis of Pharmaceuticals avoids excessive detail, presenting the key facts, backed up with pertinent examples and easy-to-digest illustrations, making it the ideal primer for those who need to understand physicochemical issues in the context of their broader field of study.
