Intestinal Absorption of Alogliptin Is Mediated by a Fruit-Juice-Sensitive Transporter.

Alogliptin (ALG), an inhibitor of dipeptidylpeptidase-4, is used in the management of type 2 diabetes mellitus, and has a high absorption rate (>60-71%), despite its low lipophilicity (logP=-1.4). Here, we aimed to clarify the mechanism of its intestinal absorption.
