Summary

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 introduction to this subject as well as its drug development applications. Beginning with foundations and basic terminology, it provides a thorough understanding of the challenges and barriers to oral bioavailability as well as the possibilities for improving this parameter. The result 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 scientists working in drug discovery and development; researchers in chemistry, biology, pharmacology, and other related fields; and graduate courses in drug development and delivery.
