Which bisphosphonate is administered monthly if taken orally?

• A. Risedronate
• B. Ibandronate
• C. Alendronate
• D. Zoledronic Acid

Answer: (B)

Ibandronate is a bisphosphonate that can be administered orally on a monthly basis. This medication is primarily used to prevent and treat osteoporosis in postmenopausal women. Ibandronate specifically stands out due to its dosing schedule, as it allows for a convenient oral administration once a month, making it more favorable for patients who may struggle with the daily routine required by other bisphosphonates.

In comparison to other bisphosphonates, risedronate and alendronate are typically available in daily or weekly dosages, thus differing from ibandronate’s unique monthly regimen. Zoledronic acid, on the other hand, is administered as an intravenous infusion, which markedly separates it from the oral options. Ibandronate provides an effective alternative for patients who prefer fewer dosing days, thus improving adherence to treatment in managing osteoporosis.
