This volume offers a comprehensive guide on the theory and practice of amorphous solid dispersions (ASD) for handling challenges associated with poorly soluble drugs. In twenty-three inclusive chapters, the book examines thermodynamics and kinetics of the amorphous state and amorphous solid dispersions, ASD technologies, excipients for stabilizing amorphous solid dispersions such as polymers, and ASD manufacturing technologies, including spray drying, hot melt extrusion, fluid bed layering and solvent-controlled micro-precipitation technology (MBP). Each technology is illustrated by specific case studies. In addition, dedicated sections cover analytical tools and technologies for characterization of amorphous solid dispersions, the prediction of long-term stability, and the development of suitable dissolution methods and regulatory aspects. The book also highlights future technologies on the horizon, such as supercritical fluid processing, mesoporous silica, KinetiSol®, and the use of non-salt-forming organic acids and amino acids for the stabilization of amorphous systems. Amorphous Solid Dispersions: Theory and Practice is a valuable reference to pharmaceutical scientists interested in developing bioavailable and therapeutically effective formulations of poorly soluble molecules in order to advance these technologies and develop better medicines for the future.

Download Enhancing Delivery of Poorly Water-soluble Drugs by Innovative Amorphous Solid Dispersions Book in PDF, ePub and Kindle
Poorly water-soluble drugs continue to dominate today’s drug development pipelines, and thus a multitude of technologies and solubility-enhancing methodologies have been commercialized to address this issue. One-such methodology to enhance the solubility of poorly water-soluble drugs is the development of amorphous solid dispersions. What was once considered a risky method of drug delivery (due to lack of drug kinetic stability in its amorphous state), formulating drugs as amorphous solid dispersions has grown significantly over the past two decades. Two amorphous solid dispersion-producing technologies have become well-understood for the development and successful delivery of poorly water-soluble drugs, and thus an overwhelming majority of commercialized amorphous solid dispersion products are processed by these two technologies; hot melt extrusion and spray drying. Each technology has distinct advantages and disadvantages, and thus many poorly water-soluble drugs are unable to process by either technology using conventional techniques. Thus, novel utilization of excipients and processing methods is necessary to continually expand the formulation design space. Furthermore, the development and commercialization of novel amorphous solid dispersion-producing technologies is necessary to further-expand the formulation design space. Therefore, the following research is an effort to expand the formulation design space of poorly water-soluble drugs while forming amorphous solid dispersions. The following research focuses on continued innovation in the field of amorphous solid dispersions to enhance the bioavailability of poorly water-soluble drugs. These research directions demonstrate innovative use of an ordinary excipient to enhance delivery of amorphous solid dispersions processed by hot melt extrusion. Additionally, these studies demonstrate the use (and further understanding) of a novel technology, KinetiSol, that allows for processing amorphous solid dispersions without the necessity of external thermal input or solvent(s). KinetiSol-processed materials are compared with spray dried materials to evaluate the kinetics behind drug release of a weakly basic drug processed with an ionic polymer, and findings from this study will be essential for future delivery of amorphous solid dispersions of weakly basic drugs in ionic polymers

Download Computational Pharmaceutics Book in PDF, ePub and Kindle
Molecular modeling techniques have been widely used in drug discovery fields for rational drug design and compound screening. Now these techniques are used to model or mimic the behavior of molecules, and help us study formulation at the molecular level. Computational pharmaceutics enables us to understand the mechanism of drug delivery, and to develop new drug delivery systems. The book discusses the modeling of different drug delivery systems, including cyclodextrins, solid dispersions, polymorphism prediction, dendrimer-based delivery systems, surfactant-based micelle, polymeric drug delivery systems, liposome, protein/peptide formulations, non-viral gene delivery systems, drug-protein binding, silica nanoparticles, carbon nanotube-based drug delivery systems, diamond nanoparticles and layered double hydroxides (LDHs) drug delivery systems. Although there are a number of existing books about rational drug design with molecular modeling techniques, these techniques still look mysterious and daunting for pharmaceutical scientists. This book fills the gap between pharmaceutics and molecular modeling, and presents a systematic and overall introduction to computational pharmaceutics. It covers all introductory, advanced and specialist levels. It provides a totally different perspective to pharmaceutical scientists, and will greatly facilitate the development of pharmaceutics. It also helps computational chemists to look for the important questions in the drug delivery field. This book is included in the Advances in Pharmaceutical Technology book series.

Solid dispersion technology has proved to be a powerful technique in the field of drug delivery of poorly water soluble drugs by enhancing the dissolution rate and bioavailability of that drug. Here we used four drugs namely Spironolactone, Etoricoxib, Ibuprofen and Carvedilol. Solid dispersions were prepared by solvent co-precipitation method, where acetone was used as solvent and pet-ether was used as anti solvent. Different water soluble polymer (HPMC 6cps, Kollicoat IR, Kollidon VA 64 and HPC), and as an excipient poloxamer were used to prepare solid dispersion. Paddle type dissolution apparatus was used to study in-vitro dissolution rate, where paddle speed was 75 rpm. at 37 C. The dissolution samples were then analyzed spectrophotometrically by UV-VIS spectrophotometer. At first we tried to identify the effect of poloxamer 407, then with poloxamer others polymer were applied to find out their effect on drugs. Through the entire study, we searched for the suitable polymer and excipient with their proportion in a formulation which would show the best beneficial effect on drugs' dissolution rate."
