Treatment SummaryEtidronic acid is a type of medication used to regulate calcium levels in the body. It was the first drug of its kind when it was approved by the FDA in 1977, but has since been replaced by newer drugs, known as nitrogen-containing bisphosphonates.

Effectiveness
How Didronel Affects PatientsEtidronic acid is a medication that stops bone from breaking down. It is considered to be very safe, even when taken in large doses, and its effects can last a long time. However, it can cause issues in the upper digestive tract, so patients should be aware of this before taking it.
How Didronel works in the bodyBisphosphonates are taken into the bones, where they bind to a mineral called hydroxyapatite. Bone resorption by osteoclasts creates an acidic environment that forces the bisphosphonates out of their binding site and into the osteoclast. Once in the osteoclast, the bisphosphonates interfere with the osteoclast's ability to break down the bones. This prevents the resorption of bones by the osteoclast. Early generation bisphosphonates mimic a molecule called pyrophosphate, which cannot be broken down, and thus stops all energy-dependent functions of

Answered by AI
Is Didronel a bisphosphonate?
"Didronel is a medicine that affects how bones are formed and broken down in the body. This can slow down the loss of bone mass, and may help to prevent fractures. Didronel is used to treat a condition called Paget's disease, which affects the bones."
Answered by AI
Is etidronate discontinued?
"This drug is not available in the U.S. The recommended dose was 7.5 mg/kg IV infusion once daily, administered for 3 consecutive days. Etidronate was designated an orphan drug by the FDA for this indication; however, etidronate therapy has been replaced with more potent bisphosphonates for this condition."
