Bisphosphonate Comparison Table and Clinical Pearls

Bisphosphonates are frequently used in the management of osteoporosis. They are often the go-to agent for this condition. Below we provide a bisphosphonate comparison table and I also wanted to highlight some of the most important clinical pearls that we should teach our patients and colleagues.

Oral administration of bisphosphonates is not something to take lightly. These drugs have strict requirements. Oral bisphosphonates should be administered first thing in the morning and prior to any food or medications. In addition, it should be taken with a full glass of water with the patient remaining upright for 30 minutes. This helps prevent esophagitis. Avoiding coadministration with food and other medications helps aid in maximizing absorption of the drug.

Another challenge with bisphosphonates is the length of use. 5 years is the magic number with oral bisphosphonates. That is the time to reassess if longer-term therapy is warranted or not. This decision is usually based upon the risk for future fracture when looking at the patient’s previous history.

Renal function is important to monitor with the use of bisphosphonates. Zoledronic acid is contraindicated if renal function is below 35 mls/min. Using oral bisphosphonates is controversial in patients with a GFR of less than 30 mls/min. In practice, I’ve seen it done. The challenge is that there isn’t a lot of clinical literature either supporting the safety of use or demonstrating harm if used in patients who have a GFR of less than 30 mls/min.
