Prasugrel [Power / Sample Size]
Hi
For all who want to know more about prasugrel bioavailability and hints for bioequivalence I suggest:
Seiler D, Doser K, Salem I.: Relative bioavailability of prasugrel free base in comparison to prasugrel hydrochloride in the presence and in the absence of a proton pump inhibitor. Arzneimittelforschung. 2011;61(4):247-51.
Please be advised that if lansoprazole is used to raise the pH level in the upper gastro-intestinal tract, AUC is decreased by 25% after administration of prasugrel hydrochloride and by 41% after prasugrel free base. In addition, the peak plasma levels are decreased by 52% and 72%, respectively (geom. means). The relative bioavailability of the prasugrel free base compared to prasugrel hydrochloride, both in the presence and in the absence of the proton pump inhibitor lansoprazole, differs so much that most probably a generic formulation containing prasugrel free base will not be equivalent in all aspects to the originator product.
Kind regards
Dan
