Whats An In Vitro In Vivo Correlation (IVIVC)?

Drug Development, Generic Drugs, Industrial Use, IVIVC, PBPK

During the development of oral drug formulations, its important to find out if the right drug concentration arrives at the desired place of action.

Drug absorption is measured in vivo, in other words in a human (or animal) body. Typical in vivo indicators are time – blood plasma concentration profiles of drugs after oral administration. To identify the parameters involved in drug absorption in vitro investigations are usually performed. In vitro literally means in glass and depicts an investigation performed in an artificial environment mimicking a biological condition.

To establish a reliable in vitro in vivo relationship (IVIVC) it is important that the artificial environments simulate the biological conditions as closely as possible. On that basis the experimental results can directly be connected to real outcomes in humans. During drug development and formulation exploration, in vitro solubility and dissolution should artificially mimic the in vivo drug or formulation performance in the human gastrointestinal tract. The in vitro results are then related to in vivo drug plasma concentration profiles (see danazol example below). When an in vitro in vivo correlation is established, it is used for development and optimisation of drug formulations. Research organisations often use this method to reduce costly and time intensive trials on animals and humans during formulation development.

Nowadays computer models are often used to link in vitro results with in vivo outcomes. These so called physiologically based pharmacokinetic (PBPK) models are capable of translating in vitro results into in vivo predictions. This method is defined as in vitro in silico in vivo correlation (IVISIVC).

Establishing in vitro in vivo correlations for poorly soluble drugs (also referred as BCS Class II and IV) can be challenging. When it comes to investigation of drug dissolution performance in the simulated conditions of the gastrointestinal tract, simple buffers usually are not sufficient enough. In this case, Biorelevant Media should be utilized because they closely mimic the fluids of the human (and animal) stomach and intestine. Biorelevant Media have become the gold standard for IVIVC and IVISIVC investigations of poorly soluble drugs during formulation development.

Johnny Brendell, Quality Chemical Laboratories, USA

As a contract research and development company, obtaining solubility data in biorelevant media of our clients' drug molecules is essential in order to fully understand the challenges we are facing for oral drug development. This data also allows us to design our formulations intelligently based upon the physico-chemical properties observed. In order to design a robust formulation it is imperative that the preformulation data is also robust and the consistent quality of the powders from allows us to obtain fantastic reproducibility; in addition, as they are so easy to prepare the time saving benefits can be passed on to our clients, both from a cost and time perspective.

Dr Mark Saunders, Kuecept Ltd, United Kingdom

The products are very helpful in regard to the amount of work needed for preparing the solutions. In addition, one does not have to worry for other potential issues, e.g. residual dichloromethane amounts in the rotavap.

Prof Christos Reppas, University of Athens, Greece

So far so good! Our order arrived promptly... the powder was easy to store, handle and transfer into the SGF media.

Collegium Pharmaceutical, USA

We found the powder offered a very easy, convenient and reproducible way of preparing biorelevant media. For us it was an easy entry into this field and is now an ideal support during the preparation of bioequivalence studies.

Ratiopharm, Germany

I first heard about FaSSIF/FeSSIF/FaSSGF when I started working on drug dissolution studies at Nanocopoeia. I think the powder is an excellent tool in drug dissolution and absorption studies, and that it's extremely easy to use. From what I've seen in the literature, it seems as though its use in absorption studies is the industry standard.

Cole J. Batty, Nanocopoeia Inc., USA

It took only 10 minutes to prepare FaSSIF, this powder makes it easy to use biorelevant media.

Shionogi & Co. Ltd, Japan, Japan


FaSSIF/FeSSIF/FaSSGF is a very easy substance to use in our lab. It is easy to store and the website offers a great resource for actually making the media.

Metrics Inc, USA

We would consider the reproducibility of the measurements to be good. We routinely use the powders to make solubility and dissolution measurements in FaSSIF and FeSSIF and find them easy to work with, efficient (in both economic and temporal terms) and reproducible.

Sirius Analytical, United Kingdom

I found the powder very easy to work with, and if there is no solubility issue with the drug, it works great and it's comparable to the conventional FaSSIF/FeSSIF media with egg lecithin which are too expensive and hard to work with.

Watson Laboratories, USA

The powder is very useful and makes it easy to mimic the gastrointestinal system.

Ana Rute Neves, ICETA (University of Porto), Portugal

We routinely use powders from in our transfer model to examine the supersaturation and precipitation behaviour of poorly soluble drugs. Not only is the media considerably quicker to prepare but its preparation is also significantly safer as dichloromethane is no longer required. We have been very happy using the media so far and will continue to use the powders in the future.

Dr Edmund Kostewicz, University of Frankfurt, Germany

The powder is really good to show how APIs and formulations work under biorelevant conditions. It is easy to use and handle. We test many APIs with powder from and have had good results.
