Wiley Interdisciplinary reviews. Free to read. Bioavailability is referred to as the extent and rate to which the active drug ingredient or active moiety from the drug product is absorbed and becomes available at the site of drug action. The relative bioavailability in terms of the rate and extent of drug absorption is considered predictive of clinical outcomes. In , the United States Food and Drug Administration FDA was authorized to approve generic drug products under the Drug Price Competition and Patent Term Restoration Act based on evidence of average bioequivalence in drug absorption through the conduct of bioavailability and bioequivalence studies.

If your institution subscribes to this resource, and you don't have a MyAccess Profile, please contact your library's reference desk for information on how to gain access to this resource from off-campus. Please consult the latest official manual style if you have any questions regarding the format accuracy. Define bioavailability, bioequivalence, and drug product performance. Explain why first-pass effect as well as chemical instability of a drug can result in low relative bioavailability. Explain why bioequivalence may be considered as a measure of drug product performance. Describe various methods for measuring bioavailability and the advantages and disadvantages of each.

Generic drugs contribute to modern healthcare by accomplishing effective, safe, and low- cost alternatives to currently available modern medicines. For drugs beyond their period of patent exclusivity insurers and patients often prefer the lower cost alternative of generics. If you trace back the evolution of the pharmaceutical industries, it is visible that the production and sale of generic medications have increased in recent years. Also, the U. It is also important to understand the key concepts related to bioavailability and bioequivalence along with the considerations that need to be kept in mind while conducting these studies. Bioavailability is a key indicator of drug absorption.

The existence of sequence effect in cross-over Bioequivalence trials

Analyze bioequivalence study data with industrial strength. Sample size could be determined for various crossover designs, such as 2x2 design, 2x4 design, 4x4 design, Balaam design, Two-sequence dual design, and William design. Design and Analysis of Bioavailability and Bioequivalence Studies.

Глаза Сьюзан неотрывно смотрели на Танкадо. Отчаяние. Сожаление. Снова и снова тянется его рука, поблескивает кольцо, деформированные пальцы тычутся в лица склонившихся над ним незнакомцев. Он что-то им говорит.
