What is FaSSCoF?
It’s a ‘biorelevant’ dissolution medium that simulates human colonic fluid before eating food:
- FaSSCoF: Fasted State Simulated Colonic Fluid
Testing your product in Biorelevant Media can help predict what will happen when it enters the gastro-intestinal tract. This is because the media are physiologically discriminating: they contain biological surfactants (bile salts and lecithin) that can have a big impact on drug solubility. Conventional buffers and surfactants (such as sodium lauryl sulfate) do not replicate the complex environment of the GI tract anywhere near as accurately.
FaSSCoF is particularly useful for testing products with an 'extended release' dosage form where absorption in the colon is targeted.
Why do I need it?
Testing in physiologically relevant media can help determine:
Biorelevant solubility: how much drug dissolves in the Biorelevant Medium
Estimated cost: $0.40 (based on 2 glass vials of 10ml FaSSCoF made from COFAS01)
Biorelevant dissolution: how much time drug takes to dissolve in the Biorelevant Medium
Estimated cost: $45 (based on 6 dissolution vessels of 500ml FaSSCoF made from COFAS02)
These in vitro tests can significantly reduce the amount of costly in vivo experiments needed because they can help you identify promising drug candidates and distinguish good formulations from bad ones.
How do I make them?
We use the highest grade of ingredients and analyze their purity before manufacture. The powders are made in our factory in London where we carefully control every aspect of their production. They are only released after rigorous analysis by a GMP certified laboratory in Germany. All products are supplied with a Certificate of Analysis. These steps ensure you will get highly reproducible results from our products every time you use them.
I've always gotten reliable and reproducible data with the products that helped the formulations department better adjust their experiments to produce desired dissolution profiles. Love the wide range of media as well!
