Synopsis The modern pharmacist burdens the onus of ensuring quality of the drugs compounded and dispensed to a patient. As such, knowledge of the internal composition of drugs, the biological processes that operate upon them in the patient's body, and their effectiveness, are all vital concerns which a pharmacist must take into account. It is within the folds of these concerns that both biopharmaceutics and pharmacokinetics play a crucial Role. Enumerating upon the principles, practices, processes and techniques which lie behind both biopharmaceutics and pharmacokinetics, this book in the series on pharmacy is concerned with the mechanics operating behind drug conception and design. Apart from being a handbook on the two sciences, the referral also covers the issues lying behind them, including those of the ethical regulations which control the practice of the two, and the scientific and medical implications they pose. In addition, effort has been undertaken in the field, and what they project for the future. It is hoped that the comprehensive and information content of the book serves well for students and teachers of pharmacy alike.
