5 I. 2004615'19 dc212003051451 2004 by CRC Press LLC Dedication To Professor Shamsuz Zoha, my first pharmacy teacher, who inspired many with his passion for the profession and for science 2004 by CRC Press LLC Preface to the Series No industry in the world is more highly regulated thanthe Pharmaceutical industry because of potential threat toa patient s life from the use of Pharmaceutical cost of taking a new chemical entity (amortized overthe cost of all molecules racing) to final regulatoryapproval is a staggering $800 million, making the phar- maceutical industry one of the most research-intensiveindustries in the world.

6 In the year 2004, it is anticipatedthat the industry will spend about $20 billion on researchand development. The generic market of drugs as the newentities come off patent is one of the fastest growingsegments of the Pharmaceutical industry, with every majormultinational company having a significant presence inthis many stages of new drug development areinherently constrained with time, the formulation of drugsinto desirable dosage forms remains an area where expe-diency can be practiced with appropriate knowledge bythose who have mastered the skills of Pharmaceutical for-mulations.

7 The HANDBOOK of Pharmaceutical Manufactur-ing Formulations is the first major attempt to consolidatethe available knowledge about formulations in a compre-hensive, and by nature a rather voluminous, book is divided into six volumes, based strictlyon the type of formulation science involved in the devel-opment of these dosage forms: sterile products, com-pressed solids, uncompressed solids, liquid products,semisolid products, and OTC products. The separation ofOTC products even though they may easily fall into oneof the other five categories is made to comply with theindustry norms of separate research divisions for OTCproducts.

8 Sterile products require skills related to steril-ization of product, and of less importance is the bioavail-ability issue, which is an inherent problem of compresseddosage forms. These types of considerations have led tothe classification of products into these six volume includes a description of regulatory fil-ing techniques for the formulations described. Alsoincluded are the current regulatory guidelines on cGMPcompliance specific to the dosage form. Advice is offeredon how to scale up the production is expected that formulation scientists will use thisinformation to benchmark their internal development pro-tocols and cut the race to file short by adopting formulaethat have survived the test of time.

9 Many of us who haveworked in the Pharmaceutical industry suffer from a closeparadigm when it comes to selecting formulations notinvented here perhaps reigns in the mind of many sea-soned formulations scientists subconsciously when theyprefer to choose only a certain platform for is expected that with the quick review of possibilitiesavailable to formulate made available in this book, scien-tists will benefit from the experience of the teachers of formulation sciences, this seriesoffers a wealth of information.

10 Whether it is a selectionof a preservative system or the choice of a disintegrant,the series offers a wide choice to study and have assisted me in the development of thiswork that has taken years to compile, and I thank scoresof my graduate students and colleagues for their help. Awork of this size cannot be produced without errors,although I hope that these errors do not distract the readerfrom the utility of the book. I would sincerely appreciateif readers point out these mistakes for corrections in futureeditions.
