How many litres do you require?

                             

FEDGAS simulates fed state gastric fluids. You can harness its power in your laboratory to discriminate significant formulation differences between your Test Product and the Reference. 900ml of this biorelevant dissolution medium contains the 62.5g of fat present in the high-fat meal along with bile salts present at physiological levels found in the fed stomach. Testing in it is particularly useful for lipophilic water insoluble drugs because good physiological dissolution conditions are created for these drugs.

Three types of fed state gastric media (at pH 6, pH 4.5 and pH 3) can easily be prepared using FEDGAS Gel and the appropriate diluted FEDGAS Buffer Concentrate. These three dissolution media reflect the different states of stomach emptying:

Generating and comparing dissolution profiles in the right biorelevant media helps reduce the risk of an expensive failed human bioequivalence study due to differences in formulation. Matching the dissolution profile of your Test Formulation to the Originator in FEDGAS will maximise the chances of achieving successful bioequivalence. In vitro biorelevant dissolution helps identify a Test formulation that matches the release rate of the Reference in vivo.
