Colloidal drug delivery systems present a range of therapeutic benefits in the treatment of a number of challenging conditions, allowing researchers to cross barriers that have previously prevented efficient treatment while offering improved and more targeted absorption. Summarizing recent research in the field, Colloids in Drug Delivery assembles

This volume provides a single-source of reviews for all the important colloidal drug delivery systems, including nanoparticles, liposomes, niosomes, microemulsions and ointments. Over 1000 bibliographic citations, as well as tables, drawings, equations and photographs, are provided. Arranged in order of increasing physical complexity, this work ana

Colloid and Interface Science in Pharmaceutical Research and Development describes the role of colloid and surface chemistry in the pharmaceutical sciences. It gives a detailed account of colloid theory, and explains physicochemical properties of the colloidal-pharmaceutical systems, and the methods for their measurement. The book starts with fundamentals in Part I, covering fundamental aspects of colloid and interface sciences as applied to pharmaceutical sciences and thus should be suitable for teaching. Parts II and III treat applications and measurements, and they explains the application of these properties and their influence and use for the development of new drugs. Provides a clear description of the fundamentals of colloid and interface science relevant to drug research and development Explains the physicochemical/colloidal basis of pharmaceutical science Lists modern experimental characterization techniques, provides analytical equations and explanations on analyzing the experimental data Describes the most advanced techniques, AFM (Atomic Force Microscopy), SFA (Surface Force Apparatus) in detail

Colloidal carriers (particles, emulsions) for intravenous administration are a promising approach to achieve controlled release and site-specific delivery of drugs. The success of the systems will depend on their ability to maintain in blood circulation (controlled release system) or to reach target cells (e.g., bone marrow, blood cells). It is well known that the surface properties of i.v. injected particles are important factors determining the organ distribution and fate in vivo. Controlled surface modification could therefore be used to direct the carriers to the desired tissues. This book deals with the physico-chemical characterization of colloidal drug delivery systems and the influence of these parameters upon in vitro cell uptake and in vivo tissue distribution. Within the book, several different methods and their effect on surface characterization are discussed, and the in vivo tissue distribution of nanoparticles different in size and surface properties (coatings with Poloxamer/Polaximine/ethoxylated nonylphenols) and the carrier properties are examined in detail. The book does not deal with single aspects, but offers a comprehensive treatment of the subject. As a result, the book contributes to a better understanding of the factors influencing the organ distribution of i.v. drug carriers and provides useful information for the rational design of new carriers. It succeeds in clearing the way for future developments and the optimization of carriers for controlled drug delivery.

The important role of ?nely dispersed matter and surfaces in medicine is not always fully understood and appreciated. Speci?cally, ?ne particles (solid or liquid) in the size range of several nanometers to several micrometers have a tremendous effect on our lives, because they can be bene?cial or detrimental to our well-being. Such particles are present in living bodies as red blood cells or cholesterol crystals in the gall bladder. They are ubiquitous in the environment, where they can cause many diseases, such as asbestosis, silicosis, and black lung disease, but they are also used in diagnostic tests, drug delivery, and numerous other applications. More recently, evidence has become available that drug formulations with active components in a ?nely dispersed state may signi?cantly affect their functionality. Furthermore, with miniaturization of medical instrumentation, the size of the components is necess- ily reduced to colloid or even smaller range. This volume is a collection of several chapters dealing with diverse topics of colloids and surfaces relevant to medical applications. Thus, Siiman describes the use of optical properties of uniform colloidal particles as probes in ?ow cytometry. Giesche focuses on the preparations and properties of exceedingly uniform silica spheres for different uses, such as in chromatography. In modi?ed forms, silica p- ticles with incorporated dyes are employed in diagnostics and those combined with tiny magnetic entities in drug delivery.
