The importance of bioequivalence study in the field drug formulation

September 20, 2019

The bioequivalence study is the combination of two drugs that share the same outcome from the patients. Usually, pharmaceutical equivalence refers to the two drugs that release the active components into the bloodstream at the same amount and the rate. Then the scientist evaluates process chemistry of how the drug genetically works and its bioequivalence to the name-brand version.

Essentiality of bioequivalent study:

The essentiality of the bioequivalence study is discussed below;

In vivo studies:

For certain drugs and dosage of those in vivo drugs documentation is very important. The proportionality of those drugs are studied either through a bioequivalent study. It is similar to a clinical pharmacodynamics study or a clinical trial.

These studies may include process chemistry through oral quick discharge drug plans either with the systemic activity. When one or more amount of drug criteria applies then it demonstrated for genetic conditions with guaranteed restorative reaction. The pharmacokinetics is entangled by the inadequate injection or retention window. After the intake of certain drugs, the reaction will be documented to maintain as a documented proof for bioavailability issue. That is related to the medication or medications of comparable structure of substance.


The early and late clinical trials definitions and plans utilized as one of the part of clinical trial and strength studies if they are distinctive the clinical trials will be detailed and to be promoted as medication product.

Application of bioequivalence studies:

  1. Comparative bioequivalence:

The bioavailability studies are done whether for a non-specific item or a new item. The test will be conveyed to acknowledge the quantitative nature of a particular item examination. This type of examination is done for a new drug. For case, when the drug is given as an oral definition concerning that of an intravenous dosage. Then oral bioequivalence data about the drug will be got by the contrasting of studies through intravenous dose.

  1. Comparative drug products:

The comparative drug product study will be helpful in the commercial centre to focus on non-specific item. In this event, the identity will be illustrated. Through this study, the measurements for the non-exclusive item are taken as remedially comparable to the inventive medication item.

  1. Fasting or feed conditions:

The bioequivalence studies are conducted under both the fasting condition as well as in the fed. This test is considered to be the most sensitive to detect the potential difference between both formulations. The summary of the product characteristics are recommended through the intake reference of the product on an empty stomach or before the food intake. Here the bioequivalent study should be performed under fasting condition but the summary of product characteristics recommends intake of the product only in the fed stage. Some of the product formulation characteristics the bioequivalent study is conducted on both fed state and fasting state.

Bottom line

The bioequivalence study will help in finding the similarity and comparison of two drugs which comes out from the patients. By the help of ingestion, the result can be obtained, for that this article will be helpful.
