Development and evaluation of a biorelevant medium simulating porcine gastrointestinal fluids.

Simulated human intestinal media, have proved to be a useful biopharmaceutics tool as a dissolution media for predicting in vivo dissolution and pharmacokinetic profile in humans. During drug product development preclinical animal models are also required to assess drug product performance, and there is a need to develop species specific intestinal media to similarly predict in vivo pharmacokinetic profiles in each preclinical model. Pigs, are increasingly being used in preclinical drug development, however to date there is a lack of quantitative information about the composition of porcine gastrointestinal (GI) fluids.
