Book Description
The suspension dosage form has long been used for poorly soluble active ingre- ents for various therapeutic indications. Development of stable suspensions over the shelf life of the drug product continues to be a challenge on many fronts. A good understanding of the fundamentals of disperse systems is essential in the development of a suitable pharmaceutical suspension. The development of a s- pension dosage form follows a very complicated path. The selection of the proper excipients (surfactants, viscosity imparting agents etc.) is important. The particle size distribution in the finished drug product dosage form is a critical parameter that significantly impacts the bioavailability and pharmacokinetics of the product. Appropriate analytical methodologies and instruments (chromatographs, visco- ters, particle size analyzers, etc.) must be utilized to properly characterize the s- pension formulation. The development process continues with a successful scale-up of the manufacturing process. Regulatory agencies around the world require cli- cal trials to establish the safety and efficacy of the drug product. All of this devel- ment work should culminate into a regulatory filing in accordance with the regulatory guidelines. Pharmaceutical Suspensions, From Formulation Development to Manufacturing, in its organization, follows the development approach used widely in the pharmaceutical industry. The primary focus of this book is on the classical disperse system – poorly soluble active pharmaceutical ingredients s- pended in a suitable vehicle.

Book Description
Many chemical substances or compounds - organic or inorganic, natural or synthetic - are not used in their pure form. In order for the active ingredient to be most effective or to obtain the ideal delivery form for the market, the actual synthesis and purification steps are followed by formulation to give end products that range from powders, agglomerates, and granules to suspensions, emulsions, microemulsions, microcapsules, instant preparations, liposomes, and tablets. Formulation combines colloid and surface chemistry with chemical process engineering; sometimes it consists of a simple mixing operation, sometimes it requires an entire series of rather complicated engineering procedures such as comminution, dispersion, emulsification, agglomeration or drying. This book covers basic physico-chemical theory as well as its applications in the chemical industry for the production of pharmaceuticals, agrochemicals, pigments and dyes, food, detergents, cosmetics and many other products; it also provides chemists and chemical engineers with the necessary practical tools for the understanding of the structure/ activity relationship.
