`Foreword
`
`I was a faculty member at the University of Tennessee and a colleague of Dr. Kenneth Avis
`when he conceived, organized, and edited {along with H.A. Lieberman and L. Lachman} the
`first edition of this book series that was published in 1984. It was so well received by the
`pharmaceutical science community that an expanded three—volume second edition was
`published in 1992. Dr. Avis did not survive long enough to oversee a third edition, and it was
`questionable whether a third edition would ever be published until two of his graduate
`students, Drs. Nema and Ludwig, took it upon themselves to carry on Dr. Avis’ tradition.
`Their oversight of this third edition is work that their mentor would be highly pleased
`and proud of. From 29 chapters in the second edition to 43 chapters in this new edition, this
`three—volume series comprehensively covers both the traditional subjects in parenteral science
`and technology as well as new and expanded subjects. For example, separate chapter topics in
`this edition not found in previous editions include solubility and solubilization, depot delivery
`systems, biophysical and biochemical characterization of peptides and proteins, container—
`closure integrity testing, water systems, endotoxin testing, focused chapters on different
`sterilization methods, risk assessment in aseptic processing, visual inspection, advances in
`injection devices, RNAi delivery, regulatory considerations for excipients,
`techniques to
`evaluate pain on injection, product specifications, extractables and leachables, process
`analytical technology, and quality by design.
`The editors have done an outstanding job of convincing so many top experts in their
`fields to author these 43 chapters. The excellent reputations of the authors and editors of this
`book will guarantee superb content of each chapter. There is no other book in the world that
`covers the breadth and depth of parenteral science and technology better than this one. In :my
`Opinion, the editors have achieVed their Primary objectives publishing a book that contains
`current and emerging sterile product development and manufacturing information, and
`maintaining the high standard of quality that readers would expect.

`

`Preface
`
`Pharmaceutical Dosage Forms: Parenteral Medications was originally published in 1984 and
`immediately accepted as a definitive reference in academic institutions and the pharmaceutical
`industry. The second edition was published in 1993. The ensuing years have produced
`incredible technological advancement. Classic small-molecule drugs are now complemented
`by complex molecules such as monoclonal antibodies, antibody fragments, aptamers,
`antisense, RNAi therapeutics, and DNA vaccines. There have been significant innovations in
`delivery devices, analytical techniques, in—silico modeling, and manufacturing and control
`technologies.
`In addition,
`the global regulatory environment has shifted toward greater
`emphasis on science—based risk assessment as evidenced by the evolving cGMPs, quality by
`design (QbD), process analytical technology (PAT), continuous processing, real time release,
`and other initiatives. The rapidly changing landscape in the parenteral field was the primary
`reason we undertook the challenging task of updating the three volumes. Our objectives were
`to (i)
`revise the text with current and emerging sterile product development and
`manufacturing science and (ii) maintain the high standard of quality the readers expect.
`The third editiOn not only reflects enhanced content in all the chapters, but also more
`than half of the chapters are new underSCoring the rapidly advancing technology. We have
`divided the volumes into logical Subunits volume 1 addresses formulation and packaging
`aspects; volume 2, facility design, sterilization and. processing: and volume 3, regulations,
`validation and future directions. The authors invited to contribute chapters are established
`leaders with proven track records in their specialty areas. Hence, the textbook is authoritative
`and contains much of the collective experience gained in the (bio)pharmaceutical industry over
`the last two decades. We are deeply grateful to all the authors who made this work possible.
`Volume 1 begins with a historical perspective of injectable drug therapy and common
`routes of administration. Formulation of small molecules and large molecules is presented in
`depth,
`including ophthalmic dosage forms. Parenteral packaging options are discussed
`relative to glass and plastic containers, as well as elastomeric closures. A definitive chapter is
`provided on container closure integrity.
`Volume 2 presents chapters on facility design, cleanroom operations, and control of the
`environment. A chapter discussing pharmaceutical water systems is included. Key quality
`attributes of sterile dosage forms are discussed, including particulate matter, endotoxin, and
`sterility testing. The most widely used sterilization techniques as well as processing
`technologies are presented. Volume 2 concludes with an in—depth chapter on lyophilization.
`Volume 3 focuses on regulatory requirements, risk—based process design, specifications,
`le3, and extractables/leachables.
`In addition, we have included chapters on parenteral
`administration devices, siRNA delivery systems, injection site pain assessment, and control,
`I’AT, and rapid microbiology test methods. Volume 3 concludes with a forward—looking
`chapter discussing the future of parenteral product manufacturing.
`These three volumes differ from other textbooks in that they provide a learned review on
`developing parenteral dosage forms for froth small molecules and biologics. Practical guidance
`is Provided, in addition to theoretical aspects, for how to bring a drug candidate forward from
`discovery,
`through preclinical and clinical development, manufacturing, validation, and
`eventual registration.
`The editors wish to thank Judy Clarkston and Lynn O’TooleBird (Pfizer, Inc.) for their
`invaluable assistance and organizational support during this project, and Sherri Niziolek and
`Bianca Turnbull (Informa Healthcare) for patiently leading us through the publishing process.

`1 Parenteral dosage terms: introduction
`and historical perspective
`John D. Ludwig
`
`INTRODUCTION
`
`Parenteral dosage forms are those administered directly into body tissues rather than via the
`alimentary canal. “ arenteral” is derived from the Greek words para (beside) and enters” (the
`intestine) and most often refers to subcutaneous (SC), intramuscular (IM}, or intravenous (IV)
`administration of drugs. Parenteral drug delivery can pose significant risk to the patient since
`the natural barriers of the body (gu t, skin, and mucous membranes} are bypassed. The highest
`standards for quality and purity must be maintained throughout dosage form manufacture to
`protect
`the patient
`from physical, chemical, and microbial contaminants. A single
`contaminated vial out of a batch of thousands can seriously injure a patient (or worse).
`Further, if improper or poor aseptic technique is used while administering an injection the
`patient could be similarly harmed. The minimum quality standards for pharmaceutical
`manufacturers are expressed in the current good manufacturing practices (oCMPs), which are
`constantly evolw'ng as technology advances. An equal burden of responsibility is placed on
`physicians, pharmacists, nurses, and other health professionals to follow strict good aseptic
`practices (GA I’s} as they administer parenteral dosage forms to patients. Nosocornial infections
`associated with parenteral drug therapy remain a significant issue (1 4}.
`
`ADVANTAGES AND DISADVANTAGES OF PARENTERAL DRUG DELIVERY
`
`Parenteral drug delivery provides a number of advantages for the patient. The parenteral route
`provides an effective way to dose patients who are unconscious or those who cannot or would
`not take oral medications. A drug ad ministered pa renterally generally produces an immediate
`therapeutic effect and is therefore desirable in emergency situations. Parenteral administration
`also provides a mechanism for dosing drugs that are not bioavailable via noninjectable routes
`such as many protein and peptide therapeutics. Total parenteral nutrition can be provided for
`seriously ill patients where tube feeding is not an alternative. In addition, large amounts of
`fluid and electrolytes can be given relatively quickly via the IV route to patients with serious
`fluid loss from dehydration or gastrointestinal infections.
`A significant disadvantage of injectable drug administration is that once a drug has been
`dosed it is difficult to reverse its effect. For example, in the event of a closing error (overdose)
`With an oral tablet, gastric lavage, induced emesis, or activated charcoal can be employed. The
`options for reversing an IV overdose are usually very limited. Secondly, the risk of infection is
`always present with parenteral dosing both in the hospital/clinic setting as well as home
`administration. Finally, the cost per dose of parenteral drugs is typically higher than for oral
`medications.
`
`PARENTERAL DRUG DELIVERY ROUTES
`
`Routes of parenteral drug delivery are summarized in Table 1. SC, 1M, and IV are the most
`common modes of administration. The fastest onset of action is achieved via the IV route since
`
`the injection is directly into a vein. Relatively large amounts of fluid can be delivered quickly
`and efficiently using the IV route. Slower and more variable onset of action typically occurs
`following SC and IM administration since the drug must be absorbed into the bloodstream
`from the site of injection. The absorption step can be exploited for drugs requiring chronic
`administration. Formulations can be designed to provide sustained—release profiles therefore
`reducing the number of injections required and the associated risk. Examples of "depot”
`formulations include DEPO—PROVERA'“' Contracgptive Injection, which is administered deep
`IM every 13 weeks and depo—subQ provera 104 which is administered SC in the anterior
`thigh or abdomen every 12 to 14 weeks. Intravitreal dosing has increased significantlyin recent

`years because of new treatments for neovascular wet age-related macular degeneration {AMD}
`such as Lucentis'n' (ranibizumb injection} and Macugen"" (pegaptanid sodium injection). The
`intradermal (ID) route is commonly used for very small volume injections (0.1 mL} such as the
`tuberculosis skin test [or tuberculin purified protein derivative (PPD) test].
`Intra—articular
`injections directly into joint synovial fluid are routinely used to administer corticosteroids or
`hyaluronic acid derivatives to relieve the symptoms of osteoarthritis. lntrathecal (intraspinal)
`and intraepidural injections are used to deliver anesthesia, analgesics, anti—infectives, and
`some cancer therapies. Intracisternal administration is used to deliver critical therapeutics
`directly to the caudal region of the brain. Less common parenteral routes include intra-arterial,
`intracardiac (e.g.. epinephrine for cardiac resuscitation), intrapleural,
`intraperitoneal, and
`intraosseous (bone) (5,6).
`
`QUALITY ATI'HIBUTES 0F PAHENTEFIAL DOSAGE FORMS
`
`Quality attributes specific to parenteral dosage forms are shown in Table 2. lnjectable products
`must be manufactured using the highest quality active drug substance and excipients. The
`regulatory review process requires that each ingredient in the formulation must be justified as

`to why it was included and the relative amount. As a general rule, formulations with the
`fewest excipients and simplest composition are highly desired. The quality and robustness of
`the container—closure system must also be described and justified relative to extractables/
`leachables, container integrity (microbiological, oxygen transmission, moisture transmission),
`and intended clinical use. Parenteral products must be sterile, pyrogen—free, and free from
`visible particulate matter and remain so throughout shelf—life. Adverse injection site events are
`widely reported and can cause significant
`tissue damage. Often,
`the formulation can be
`modified to increase injection site tolerability, for example, by changing buffers and / or
`decreasing buffer concentration as well as rendering the dosing solution isotonic. The
`compatibility of the formulation should be assessed with the most likely drugs that will be

`
`MILESTONES IN PARENTERAL DRUG THERAPY
`
`Various scholars have summarized the development of parenteral drug therapy (7 13). A
`compiled historical timeline is presented in Table 3. The reader should be aware there is
`disagreement in the literature about exact dates as well as who was "first," particularly for

`water and electrolyte replacement therapy.
`Thomas Latta established the first clinical practice of IV infusions of water and salts to treat
`cholera patients, based on O'Shaughnessy's work.
`Alexander Wood developed the first modern hypodermic syringe with a steel barrel and hollow
`steel needle.
`Joseph Lister developed the concepts of antisepsis using carbolic acid (phenol) solutions to
`sanitize hands, instruments, and wounds to reduce postsurgery infections.
`Louis Pasteur confirmed the germ theory of disease, discovered techniques for pasteurization of
`milk, and developed vaccinations against chicken cholera, bovine anthrax, and rabies.
`Charles Chamberland invented the autoclave.
`Charles Chamberland invented the “Chamberland filter" (porcelain) that removed bacteria from
`solutions prior to dosing.
`FLM. Matas demonstrated the effective use of IV saline solutions to treat shock.
`Using a rabbit model, E.C. Hort and W.J. Penfold determined the pyrogenic response following
`many IV iniections was caused by a substance produced by gram negative bacterial
`contamination of the solution (14 16].
`Ftichard Zsigrnondy and W. Bachman developed technology to manufacture microporous
`membrane filters from cellulose esters (nitrocellulose, acetyl cellulose, cellulose acetate].
`Florence Siebert and LB, Mendel developed a definitive rabbit pyrogen test model and showed
`that endotoxin from gram negative bacteria was the substance responsible for the pyrogenic
`response following injection with sterile solutions (17 19.20].
`Frederick Banting and J.J.Fl. Macleod share the Nobel Prize in Physiology or Medicine for the
`extraction of insulin and demonstration of clinical efficacy.
`Purified insulin product marketed ("min“).
`RM. Matas demonstrates continuous IV "drip" (21).
`L. Rademaker reported that after installation of a distilled water system for pharmaceutical
`production, pyrogenic reactions by surgery patients to parenteral injections dropped from 30%
`to 4% (22).
`Lloyd A. Hall and Carroll L. Griffith patented the use of ethylene oxide to sterilize and preserve
`spices. This technology was applied to sterile pharmaceutical product manufacturing during
`the 1940s
