Etidronic acid-d3 disodium（Cat No.:S000483） is a deuterated form of etidronic acid, where three hydrogen atoms are replaced with deuterium. This modification often results in altered metabolic stability and can be used in research to study the drug’s pharmacokinetics. Etidronic acid, also known as etidronate, is a bisphosphonate used primarily to treat and prevent bone disorders like osteoporosis and Paget’s disease by inhibiting bone resorption. The disodium salt form enhances the compound’s solubility, facilitating its administration and absorption. This deuterated version helps in understanding how isotopic substitution affects the drug’s behavior and efficacy.
