Zoldonat is a prescription medication used to treat a number of bone diseases. This generic drug contains the active ingredient zoledronic acid, a type of medicine called a bisphosphonate. It can be used to:
- Treat and prevent osteoporosis in postmenopausal women at risk of bone fracture.
- Treat and prevent osteoporosis in men who are at high risk of bone fracture.
- Treat and prevent osteoporosis in men and women who are on corticosteroid therapy such as prednisolone.
- Treat bone disease known as Paget’s disease (characterized by excessive breakdown of bone and increased irregular formation of bones causing it to become deformed, enlarged, weak, painful, and prone to breaking).
- Reduce the high calcium level in the blood caused by cancer that has spread to the bones
- Treat bone pain and weakness caused by myeloma or breast cancer that has spread to the bones.
- Help protect that bones from the effect of some treatment for early breast cancer.
- Reduces the risk of early breast cancer from coming back.
Zoledronic acid was approved for medical use in the US since 2001. It is considered one of the safest and most effective drugs needed in the health system by the World Health Organization.
As a bisphosphonate, this medicine works by stopping the bone osteoclast from breaking down the bone and by reducing the turnover of the bone. Zoldonat binds very tightly to the bone and prevents the calcium from being removed by the osteoclasts. In postmenopausal women, the levels of estrogen in their blood start to decrease. As a result, there is an increase in the breakdown of the bone osteoclast which resulted in a loss of bone density.
Bone loss among menopausal women is particularly rapid for the first ten years. Over time, it may lead to the development of osteoporosis or the thinning of the bone. The bones become more porous and fragile. The result can be painful fractures. The loss of bones occurs progressively and silently, often time, there are no symptoms until the first fracture occurs.
