| Material Notes | a diphosphonate which affects calcium metabolism. it inhibits ectopic calcification and slows down bone resorption and bone turnover. Food contaminant arising from its use as a boiler water additive for prepn. of steam used in food processing. Component of antimicrobial washes for poultry carcasses and fruit Etidronic acid is a first generation (non-nitrogenous) bisphosphonate in the same family as clodronate and tiludronate. Etidronic acid affects calcium metabolism and inhibits bone resorption and soft tissue calcification. Of the etidronic acid that is resorbed (from oral preparation) or infused (for intravenous drugs), about 50% is excreted unchanged by the kidney. The remainder has a very high affinity for bone tissue, and is rapidly absorbed onto the bone surface. Etidronic acid has been shown to prevent or delay skeletal-related events and decrease bone pain as well as normalize calcium levels in the presence of hypercalcemia. |
