Zolasta 4 Mg Injection

Zolasta 4 mg belongs to the class of medications called bisphosphonates which is used to treat osteoporosis caused by menopause or long term steroid use. Osteoporosis is a bone disease that weakens or thins the bones by decreasing the bone density especially in menopausal women. This medication helps to bring down the levels of calcium in blood that is caused by some cancers. 

Key Features

How does Zolasta 4 mg work?

In healthy bones, old tissue is broken down by the cells called osteoclasts. In diseases like osteoporosis and cancer, there is faster bone destruction than it can be resolved. Zoledronic acid gets attracted to the minerals in the bones. Once it enters the bloodstream, it travels to the areas where bones are broken down the fastest. The drug is absorbed by the osteoclasts. Inside these cells, there is blockage of the chemical pathway that is needed for survival. Since the cells get deprived of the pathway, the destructive cells lose their grip on the bone and eventually die.
