Which medication is classified as an antiresorptive?

Ibandronate is classified as an antiresorptive medication because it belongs to a group of drugs known as bisphosphonates, which work by inhibiting the activity of osteoclasts—the cells responsible for bone resorption. By reducing the number of osteoclasts and their activity, ibandronate helps to decrease bone turnover and prevent bone loss, making it an effective treatment for conditions such as osteoporosis.

In contrast, abaloparatide is an anabolic agent that promotes bone formation rather than inhibiting resorption. Calcium is a vital mineral that supports bone health but does not directly act as an antiresorptive agent. Romosozumab-aqqg is also an anabolic treatment that facilitates bone formation while simultaneously inhibiting resorption, but its primary mechanism is to stimulate new bone growth. Therefore, ibandronate stands out as the medication that specifically functions to reduce bone resorption through its antiresorptive properties.
