Pharmaceutics is one of the most diverse subject areas in all of pharmaceutical science. It is concerned with the scientific and technological aspects of the design and manufacture of dosage forms or medicines. An understanding of pharmaceutics is therefore essential for all pharmacists and those pharmaceutical scientists who are involved with converting a drug or a potential drug into a high quality medicine that can be delivered safely, effectively and conveniently to the patient. Now in its fifth edition, this best-selling textbook in pharmaceutics has been comprehensively updated to reflect the rapid advances in formulation science and drug delivery methodologies for small molecules, biopharmaceuticals and nanomedicines. At the same time the editors have striven to maintain the accessibility of the text for students of pharmacy and pharmaceutical science, preserving the balance between a suitably pitched introductory text and a clear reflection of the state of the art.
