Etidronate is a bisphosphonate medication that works by slowing the breakdown of old bone cells and the formation of new bone cells. It is used in the treatment of conditions of the bone including paget's disease.
Paget's disease of the bone is a condition in which the bones are soft, deformed, weak and easily broken. Etidronate helps to strengthen the bones in patients suffering from this condition.
Etidronate can also be used after hip replacement surgery or following a spinal injury. In these cases the treatment helps to prevent the development of bone cells on materials other than the skeleton. This prevents the calcification of artificial hips and spinal implants which can otherwise restrict movement and cause further problems.
Etidronate can also be used to treat hypercalcemia in patients suffering from some forms of cancer.
Etidronate is available only when prescribed by a doctor and is taken in the form of a tablet prescribed as Didronel.
The use of Etidronate can have a wide range of unwanted side effects in the patient. While not all of the following side effects may occur, the patient may need to seek urgent medical attention in some cases where they do occur.
