Bioequivalent or Nonbioequivalent?
Pharmacological Research, 2001The current tests for bioequivalence are based on assumptions that are not valid in general; this paper shows why it is necessary to use a method that does not depend upon assumptions that cannot, and need not, be proved in general.

On Bayesian Methods for Bioequivalence
Biometrics, 1984Bayesian methods are presented for assessing bioequivalence for studies in which a new formulation and a standard are administered simultaneously, and for Latin square designs which compare two or more new formulations to a standard. Two examples illustrate the application of the methods.

The bioequivalence of two formulations of the same drug may be determined by evaluating the similarity of their respective plasma concentration curves. The similarity of two plasma concentration functions can be measured by an index called the bioequivalence index. This paper shows how such an index may be defined and calculated.

Biometrics, 1984
A number of methods have been proposed for statistical analysis of bioequivalence trials. A new method is proposed and compared to three previously suggested techniques. This comparison clarifies the relationship among the four methods and yields practical suggestions regarding statistical tests.

International Journal of Pharmaceutical Medicine, 2006
Bioequivalence has been the topic of many publications since its development in the late twentieth century for the protection of public health when changing formulations of orally administered products. This review paper describes the international regulations for this purpose and provides an outline of major steps in the development of the ...

Stereochemistry and Bioequivalence
The Journal of Clinical Pharmacology, 1992Despite the fact that many important drugs are chiral, for a variety of reasons they are marketed as racemates (i.e., an equal proportion of two enantiomers). Although enantiomers of racemic drugs often differ from one another in their pharmacodynamic and pharmacokinetic properties, bioequivalence assessments are made using nonstereospecific assays ...

Biosimilars: Are They Bioequivalent?
Digestive Diseases, 2014Biologics have revolutionized several areas of medical therapeutics, and dozens of them are used by millions of patients. Monoclonal antibodies are only one type of biologics, but more than 900 are now in different phases of development. These drugs are complex to make and not cheap.

Statistics in Medicine, 1992
AbstractThe FDA permits marketing of a generic formulation of a drug G for the same indications as a standard preparation S if one can show that G is bioequivalent to S. Present implementation requires convincing evidence that the population mean difference in bioavailability (drug exposure) between the two preparations lies within specified bounds ...

On population and individual bioequivalence
Statistics in Medicine, 1993AbstractIn a traditional assessment of the bioequivalence of two formulations of a drug one compares the average bioavailability from the two formulations. Anderson and Hauck argued that in some situations it is not sufficient to demonstrate average bioequivalence, and they proposed a method for the assessment of what they called individual ...

BIOEQUIVALENCY OF RANITIDINE TABLETS
Journal of Clinical Pharmacy and Therapeutics, 1989The bioavailability of two brands of ranitidine tablets was studied in 10 healthy volunteers. Formulation factors were compared by performing disintegration, dissolution and content uniformity tests. Plasma concentrations of ranitidine were measured using a sensitive and precise high pressure liquid chromatographic (HPLC) procedure.
