GENERALLY AVOID: Orange juice may moderately reduce the bioavailability of atenolol by interfering with its absorption from the gastrointestinal tract. In a pharmacokinetic study, subjects ingested 200 mL orange juice 3 times daily for 3 days and twice daily on the fourth day, and took 50 mg atenolol with 200 mL orange juice on day 3. The average peak plasma concentration (Cmax) of atenolol fell by 49% and the area under the concentration-time curve (AUC) fell by 40% in comparison to subjects who drank only water. In addition, the presence of food may reduce the bioavailability of atenolol by 20%. The clinical significance is unknown.

MANAGEMENT: Patients treated orally with atenolol should be advised to take atenolol at the same time each day and to avoid consumption of large amounts of orange juice to prevent any undue fluctuations in serum drug levels. Monitoring for altered efficacy of atenolol may be advisable.
