As the largest reference on pharmaceutical formulations, this handbook also provides guidelines on how to file aNDAs in the shortest possible time, helping pharmaceutical companies to cut costs in the areas of pharmaceutical research and development. Divided conveniently into two parts—regulatory and manufacturing guidelines, and formulations—each volume in the set covers: cGMP compliance pre-approval inspections stability and bioequivalence testing packaging commodity development common difficulties in formulating drugs changes to aNDAs Handbook of Pharmaceutical Manufacturing Formulations, Second Edition, Volume 1: Compressed Solid Products By Sarfaraz K.

The first volume, Compressed Solid Products, tackles these challenges head on. Highlights from Compressed Solid Products, Volume One include: formulations for more than of the most widely used drugs for all types of release profiles, offering formulators a rare opportunity to start with an optimal composition the essentials of what you need to be aware of when establishing a manufacturing process based on the formulations presented identification and inclusion of the most popular prescription products, a critical list for the selection of products Handbook of Pharmaceutical Manufacturing Formulations, Second Edition, Volume 2: Uncompressed Solid Products By Sarfaraz K.

Highlights from Uncompressed Solid Products, Volume Two include: the fundamental issues of good manufacturing practices formulations for more than pharmaceutical products, including currently approved products and innovative products such as small proteins, instantly liquifiable powders, and nanoparticles access to US FDA guidelines, as well as all major guidelines around the world identification and inclusion of the most often approved capsules and powders in the US Handbook of Pharmaceutical Manufacturing Formulations, Second Edition, Volume 3: Liquid Products By Sarfaraz K.

Highlights from Liquid Products, Volume Three include: practical details involved in complying with the current good manufacturing practice requirements in liquid manufacturing access to what an FDA auditor would be looking for during a liquid manufacturing audit issues that may arise during a US FDA inspection the protocols used for stability testing for new drugs and new dosage forms, drawn from the most current ICH guidelines Handbook of Pharmaceutical Manufacturing Formulations, Second Edition, Volume 4: Semisolid Products By Sarfaraz K. Drug manufacturers need a thorough understanding of the specific requirements that regulatory agencies impose on the formulation and efficacy determination of drugs contained in these formulations.

Whereas liquid drugs do not study protocols, particularly where a generic drug is share the compression problems of solid dosage forms, involved. It is also a good idea to benchmark the product the filling problems of powder dosage forms, and the against the innovator product.

However, one should under- consistency problems of semisolid dosage forms, they do stand clearly that the FDA is not bound to accept stability have their own set of considerations in the formulation data even though it might match that of the innovator and manufacturing stages. The considerations of prime product. The reason for this may lie in the improvements importance for liquid drugs include solubility of active made since the innovator product was approved.

For drugs, preservation, taste masking, viscosity, flavoring, example, if a better packaging material that imparts appearance, and stability chemical, physical, and micro- greater safety and shelf life is available, the FDA would biological , raw materials, equipment, the compounding like this to be used not for the purpose of shelf life, but procedures often the order of mixing , and finally the for the safety factors. In recent years, the FDA has placed packaging to allow a stable product to reach patients. Obviously, this is one it can be stable after reconstitution; therefore, limited way how the innovator controls the proliferation of generic examples are included here.

The original patents that pertain to synthesis Chapter 1 in Section I Regulatory and Manufacturing or manufacturing of the active raw material may have been Guidance describes the practical details in complying superseded by improved processes that are not likely to with the current good manufacturing practice cGMP be a part of a later patent application to protect the trade requirements in liquid manufacturing.

This chapter does secret because of double-patenting issues. The innovator not address the specific cGMP parameters but deals with often goes on to revise the specifications of the active the practical aspects as may arise during a U. Food and pharmaceutical ingredient to the detriment of the generic Drug Administration FDA inspection.

This includes manufacturer. However, my experience tells me that such what an FDA inspector would be looking into when audit- changes are not necessarily binding on the generic man- ing a liquid manufacturing facility. Drawn from the most current Interna- ence standard if one is available , there is no need to be tional Conference on Harmonization ICH guidelines, concerned about this aspect. However, manufacturers are this chapter describes in detail the protocols used for sta- advised to seek a conference with the FDA should this be bility testing not only for new drugs but also for new a serious concern.

At times, the manufacturer changes the dosage forms. The chapter is placed in this volume finished product specification as the patents expire or because stability studies are of greater concern in liquid reformulates the product under a new patent. A good dosage forms; however, keeping in mind the overall per- example of this practice was the reformulation of calcitriol spective of the series of this title, this chapter would apply injection by Abbott as its patent came to expiry.

The new to all dosage forms. Again, emphasis is placed on the specifications include a tighter level of heavy metals, but practical aspects, and the reader is referred to official a generic manufacturer should have no problem if the guidelines for the development of complete testing proto- original specifications are met because the product was cols. It is noteworthy that the ICH guidelines divide the approvable with those specifications. It the formulator is referred to the original guideline for full is noteworthy that the regulatory agencies consider con- guidance.


Stability studies constitute one of the most tainers and packaging systems, all those components that. Whereas the of inspection. The inspection guidelines provided apply industry is much attuned to studies of the effects of the to both the manufacturers of API as well as to the finished API and dosage formulation components, the study of products.

This is an imprudent practice, as it might in the formulation of liquid products. However, this chap- result in loss of valuable time. The packaging industry ter is not an all-inclusive guide to formulation. Only high- generally undergoes faster changes than do the chemical lights of points of concern are presented here, and the or pharmaceutical industries.

As a rule of lists a wide range of products that fall under this classifi- thumb, the closure system for a product should be the first cation, as interpreted in the volume. There are three levels criterion selected before development of the dosage form. First, the Bill Switching between a glass and a plastic bottle at a later of Materials is accompanied by detailed manufacturing stage can be a very expensive exercise.

The problems incum- opment that packaging scale-ups require just as much bent in the formulation of liquid products are highlighted work as does a formulation scale-up or changes. As a in Chapter 5, but these are generic problems, and the result, the FDA provides the scale-up and post-approval formulator should be aware of any specific situations or change SUPAC guidelines for packaging components.
