What do you mean by IVIVC?
What do you mean by IVIVC?
Introduction. An in vitro – in vivo correlation (IVIVC) is defined by the U.S Food and Drug Administration (FDA) as a predictive mathematical model describing the relationship between the in vitro property of an oral dosage form and relevant in vivo response.
What is IVIVC PPT?
DEFINITION OF IVIVC :- As per USP :- The establishment of rational relationship between a biological property, or parameter derived from biological property produced by dosage form, and a physiochemical property or characteristic of same dosage form.
Why IVIVC is done?
The main objective of an IVIVC is to serve as a surrogate for human bioequivalence (BE) studies, which may reduce the number of BE studies performed during the initial approval process as well as with certain scale-up and postapproval changes.
How do you develop IVIVC?
The IVIVC model is developed by using the observed fraction of the drug absorbed and that of the drug dissolved. Based on the IVIVC model, the predicted fraction of the drug absorbed is calculated from the observed fraction of the drug dissolved.
What are the various levels of IVIVC?
Levels of IVIVC. There are three primary IVIVC categories, known as Levels A, B, and C. There is also a subcategory known as multiple Level C correlation. Level A is the most common type of IVIVC and historically used primarily for NDAs and investigational new drug (IND) applications.
What is a vitro study?
In vitro is used to describe work that’s performed outside of a living organism. This can include studying cells in culture or methods of testing the antibiotic sensitivity of bacteria.
Why is IVIVC important in the development of a formulation and its quality control?
Not only does IVIVC provide a better understanding of the dosage form, but it provides a predictive tool that can eliminate the need for certain clinical BE studies, help in interpreting batch-to-batch variability, and help to optimize formulation development, thus streamlining product development and manufacturing.
Which class of drug has no IVIVC?
In vitro-in vivo correlation and its application
| Class I | High Solubility High Permeability | Correlation (if dissolution is rate-limiting step) |
|---|---|---|
| Class II | Low Solubility High Permeability | IVIVC expected |
| Class III | High Solubility Low Permeability | Little or no IVIVC |
| Class IV | Low Solubility Low Permeability | Little or no IVIVC |
What is in vitro and Invivo?
In vivo refers to when research or work is done with or within an entire, living organism. In vitro is used to describe work that’s performed outside of a living organism. This can include studying cells in culture or methods of testing the antibiotic sensitivity of bacteria.
Why bioequivalence study is important?
Bioequivalence studies are very important for the development of a pharmaceutical preparation in the pharmaceutical industry. Their rationale is the monitoring of pharmacokinetic and pharmacodynamic parameters after the administration of tested drugs.
Why bioequivalence study is done?
Bioequivalence studies are used to assess the expected in vivo biological equivalence of two proprietary preparations of a drug. If two pharmaceutical products are said to be bioequivalent, then they would be expected to be the same for all intents and purposes.
When to use IVIVC instead of in vivo studies?
When requesting biowaivers for drug manufacturing changes, IVIVC can be used in lieu of certain otherwise required in vivo studies if sufficient safety and efficacy have been established.
Which is the highest level of correlation IVIVC?
An IVIVC that correlates the entire in vitro and in vivo profiles has regulatory relevance and is called a Level A Correlation. This level of correlation is the highest category of correlation and represents a point-to-point relationship between in vitro dissolution rate and in vivo input rate of the drug from the dosage form [3,5].
How is IVIVC used in the drug development process?
IVIVC is a tool used in quality control for scale up and post-approval changes e.g. to improve formulations or to change production processes & ultimately to reduce the number of human studies during development of new pharmaceuticals and also to support the biowaivers.
How can IVIVC be used to predict bioavailability?
Once a validated IVIVC model has been established, it can be used to predict bioavailability and bioequivalence (BA/BE) based on in vitro data that are already available. In such cases, dissolution test results can be used to provide the desired information without the need for any clinical BE studies with human subjects.
