Dear Sir,

Recently I performed a Fasting and Fed study on the prasugrel molecule. In fasting condition the AUC and Cmax is meeting the BE criteria with the ratio of around 100. But unfortunately in Fed condition the AUC is meeting the BE limit same as fasting but the Cmax fails with the ratio of more than 120 % and CI limits are wider enough.
kindly suggest me the probable reason for that, should I go for the reformulation or repeat the Fed study.
or any other reason.
Your esteemed reply is quite help for me to for the Exhibit batches and final pivotal study.
