Etidronate (sodium salt)

Etidronate is a first generation, non-nitrogenous diphosphonate analog of endogenous pyrophosphate. It binds to hydroxyapatite and induces osteoclast apoptosis, thereby inhibiting abnormal bone resorption. Unlike other bisphosphonates, etidronate may also prevent bone calcification.Formal Name: P,P'-(1-hydroxyethylidene)bis-phosphonic acid, disodium salt. CAS Number: 7414-83-7.
