What form does Ibandronate take when administered intravenously?

• A. Weekly
• B. Monthly
• C. Every three months
• D. Daily

Answer: (C)

Ibandronate is a bisphosphonate medication used to treat osteoporosis and works by inhibiting bone resorption. When administered intravenously, it is typically given every three months as a single dose. This dosing schedule is designed to maintain effective levels of the medication in the body while minimizing the frequency of administration, making it more convenient for patients as compared to daily or weekly regimens.

The monthly or daily options do not align with the established protocols for intravenous ibandronate treatment, which aim to provide sufficient therapeutic effects without the burden of frequent dosing. The every three months schedule allows for sustained efficacy in improving bone density while reducing the need for continuous monitoring that more frequent dosing would require. Therefore, the choice of every three months as the correct answer reflects the standard practice for the intravenous administration of ibandronate in clinical settings.
