Drugs: etidronate (Didronel), pamidronate (Aredia), risedronate (Actonel) alendronate (Fosamax), tiludronate (Skelid), zoledronic acid (Zometa), ibandronate (Boniva) Used for bone support, most ... commonly used Pharmacodynamics Adhere to bone, inhibit osteoclastic activity, potent inhibitors of both normal and abnormal bone resorption o Etidronate (Didronel): reduces both bone resorption and bone formation because formation is coupled with resorption o Pamidronate (Aredia) (available as IV only) o and risedronate (Actonel): inhibit bone resorption with out inhibiting bone formation and mineralization o Alendronate (Fosamax): highly selective inhibitor of bone resorption 1 100 to 500 time more potent than the other drugs Does not interfere with osteoclastic recruitment or attachment but does inhibit osteoclastic activity o Tiludronate (Skelid): inhibits protein-tyrosine-phosphatease, results in detachment of osteoclasts from the bone surface Inhibits the osteoclastic proton pump o Zoledronic acid (Zometa): inhibits osteoclastic activity and induces osteoclast apoptosis Also inhibits the increased osteoclastic activity and skeletal calcium release induced by various stimulatory factors release by tumors Only available as IV formulation o Ibandronate (Boniva): inhibits osteoclast activity and reduces bone resorption and turnover based on its affinity for hydroxyapatite (part of the bone matrix) All drugs in this class reduce vertebral fracture however, o Only alendronate, risedronate, and zoledronic acid have demonstrated nonvertebral fracture reduction o Pamidronate and zoledronic acid: only for parenteral use Pharmacotherapeutics o Contraindication: uncorrected hypocalcemia, documented Barrett’s esophagus, and renal insufficiency o Caution: patient with GI disorders o R/F severe esophageal adverse reactions is greater in patients who lie down after taking these drugs or fail to take with a full glass of water o Etidronate has been withheld from patients with enterocolitis r/t diarrhea particularly at high doses Associated with fracture in patients with Paget’s disease when given high doses or when therapy lasted longer than 6 months Monitor with x-rays and lab work to assess for lesions Rare femur fracture in non-Paget’s patients using bisphosphonates o IV formulations associated with higher renal toxicity risk especially with rapid infusion Check crt prior to every dose is required, force fluids before and after infusion [Show More]
