Clinical-pharmacological groups / Group affiliation
Bone resorption inhibitor for bone metastases
Active substance:
zoledroic acid
Pharmacotherapy
Bone resorption inhibitor-bisphosphonate
Pharmacological effect:
Bone resorption inhibitor, nitrogen-containing bisphosphonate. It acts mainly on bone, suppresses osteoclasts and bone resorption.
The selective effect of bisphosphonates on bone tissue is based on a high affinity for mineralized bone tissue. Zoledronic acid is rapidly redistributed into bones and, like other bisphosphonates, is localized predominantly in bone remodeling sites.
The main molecular target of zoledronic acid in osteoclast is the enzyme farnesyl pyrophosphate synthetase (FPS)
While the possibility of other mechanisms of action is not excluded. The long period of action is determined by a high affinity for the active FPS centre and a pronounced affinity for mineralized bone tissue.
With the exception of high antiresorbative action, the effects of Zoledronic acid on bone tissue are similar to those of other bisphosphonates.
In addition to the inhibitory effect on bone resorption, Zoledronic acid has antitumor properties that provide therapeutic efficacy in bone metastases.
In vivo: inhibition of osteoclastic bone resorption, changing the microenvironment of the bone marrow, leading to a decrease in the growth of tumor cells; antiangiogenic activity. Suppression of bone resorption is also clinically accompanied by a pronounced decrease in pain.
In vitro: inhibition of osteoblast proliferation, direct cytotoxic and proapoptic activity, synergistic cytostatic effect with antitumor drugs Rezoclastin; antiadhesive/invasive activity.
Zoledronic acid, suppressing proliferation and inducing apoptosis, has a direct antitumor effect on human myeloma cells and breast cancer, and also reduces the penetration of breast cancer cells through the extracellular matrix, which indicates the presence of antimetastatic properties. In addition, Zoledronic acid inhibits the proliferation of human endothelial cells and in animals causes an antiangiogenic effect.
In patients with hypercalcemia caused by a tumor, it was shown that the action of Zoledronic acid is characterized by a decrease in the concentration of calcium in the serum and a decrease in its excretion in the urine.
Testimony Rezoclastin:
Postmenopausal osteoporosis (to reduce the risk of fractures of the femur, vertebrae and extra-vertebrate fractures, to increase bone mineral density); prevention of subsequent (new) osteoporotic fractures in men and women with proximal femoral fractures; osteoporosis in men; Prevention and treatment of osteoporosis caused by the use of GCS; Prevention of postmenopausal osteoporosis (in patients with osteopenia); Pejet's bone disease.
Osteolytic, osteoblastic and mixed bone metastases of solid tumors and osteolytic lesions in multiple myeloma, as part of combination therapy; hypercalciemia caused by a malignant tumor.
Method of administration, course and dosage:
Enter in / in drip.
The dose and treatment regimen depend on the indications from the indications, the treatment regimen used, the therapeutic effectiveness.
Drug Rezoclastin interaction
When both bisphosphonates and aminoglycosides are applied simultaneously, the serum calcium level may remain reduced for longer than required, as an additive effect on the serum calcium concentration is possible.
When used together with preparations potentially having a nephrotoxic effect, the risk of deterioration of kidney function is increased.
Use in pregnancy and breastfeeding
Use in pregnancy and during breastfeeding is contraindicated.
