Description
ORAL BIOAVAILABILITY AND DRUG DELIVERY Improve the performance and viability of newly-developed and approved drugs with this crucial guide
Bioavailability is the parameter which measures the rate and extent to which a drug reaches a user's circulatory system depending on the method of administration. For example, intravenous administration produces a bioavailability of 100%, since the drugs are injected directly into the circulatory system; in the case of oral administration, however, bioavailability can vary widely based on factors which, if not properly understood, can result in a failure in drug development, adverse effects, and other complications. The mechanics of oral bioavailability are therefore critical aspects of drug development.
Oral Bioavailability and Drug Delivery provides a comprehensive coverage of this subject as well as its drug development applications. Beginning with basic terminology and fundamental concepts, it provides a thorough understanding of the challenges and barriers to oral bioavailability as well as the possibilities for improving this parameter. The resulting book is an indispensable tool for drug development research.
Oral Bioavailability and Drug Delivery readers will also find:
Discussion questions in many chapters to facilitate comprehension
Detailed discussion of topics including dissolution, absorption, metabolism, and more
Real-world examples of methods in actions throughout
Oral Bioavailability and Drug Delivery is ideal for pharmaceutical and biotechnology scientists working in drug discovery and development; researchers in chemistry, biology, pharmacology, immunology, neuroscience, and other related fields; and graduate courses in drug development and delivery.
