Which bisphosphonate requires taking with water and staying upright for 30 minutes after to reduce esophageal irritation?

• A. Zoledronic acid
• B. Ibandronate
• C. Risedronate
• D. Alendronic acid

Answer: (D)

Esophageal irritation is a risk when taking oral bisphosphonates, because the tablet can injure the esophageal lining if it lingers there. To minimize this, the dose is taken with a full glass of water and the patient remains upright for about 30 minutes after swallowing, before eating or taking other medications. This 30-minute upright rule is the classic instruction associated with alendronic acid, which is why it’s the correct choice. Zoledronic acid is given by IV and doesn’t involve swallowing or post-dose positioning. Other oral options have their own specific guidelines, but the combination of taking with water and staying upright for 30 minutes is most characteristic of alendronic acid.
