Zolendronic Acid

Wales Cancer Trials Unit · FDA-approved active Small molecule ✓ Verified May 2026

Zolendronic Acid is a Bisphosphonate Small molecule drug developed by Wales Cancer Trials Unit. It is currently FDA-approved for Hypercalcemia of malignancy, Bone metastases in solid tumors and multiple myeloma, Osteoporosis prevention in patients receiving aromatase inhibitors for breast cancer. Also known as: Zoledronate, bisphosphonates.

Zoledronic acid inhibits osteoclast-mediated bone resorption by blocking farnesyl pyrophosphate synthase in the mevalonate pathway.

Zoledronic Acid is a small molecule used in the treatment of various conditions, including Postmenopausal Osteoporosis, Breast Cancer, Hypercalcemia of Malignancy, and Metastatic Cancer. It has been studied in clinical trials as a potential treatment for Sickle Cell Disease, although one such trial was withdrawn due to unknown reasons.

Mechanism of action

As a bisphosphonate, zoledronic acid binds to hydroxyapatite in bone and is taken up by osteoclasts, where it inhibits farnesyl pyrophosphate synthase, disrupting protein prenylation and leading to osteoclast apoptosis. This reduces bone turnover and resorption, making it effective for conditions characterized by excessive bone loss or osteolytic lesions.
