Interaction Details
Atenolol, Chlortalidone is classified as belonging to the following category: Atenolol (Tenormin)
Concomitant consumption of apple juice can significantly decrease oral absorption and blood levels of atenolol.
Pharmacokinetic research shows that coadministration of apple juice 600-1200 mL decreases levels of atenolol by 58% to 82% in a dose-dependent manner. Apple juice seems to inhibit organic anion transporting polypeptide (OATP), which is involved in drug uptake in the gut, liver, and kidney. It is thought that apple juice might affect OATP for only a short time. Therefore, separating drug administration and consumption of apple juice by at least 4 hours might avoid this interaction.
