Description

Application

Etidronate disodium hydrate has been used in the synthesis of bisphosphonate derivatives of adenosine triphosphate (ATP)by T4 RNA ligase.[1] It has also been sued to inhibit human farnesyl diphosphate synthase (FDPS).[2]

Biochem/physiol Actions

Bisphosphonate antiresorptive agent. Less potent inhibitor of farnesyl diphosphate synthase (IC₅₀ = 80 μM) as compared to the nitrogen containing bisphosphonates

Etidronate helps to guard chronic ocular hypertension prompted retinal oxidative stress. It stimulates the development of retinal ganglion cells through insulin-like growth factor 1 (IGF-1) signaling pathway. It may possess neuroprotective effects in in vivo and in vitro rat model of glaucoma. Etidronate belongs to bisphosphonates.[3]
