Ranelic acid

The chemical name of ranelic acid is 5-[bis(carboxymethyl)amino]-2-carboxy4-cyano-3-thiophenacetic acid. An experimental drug made by combining strontium with ranelic acid has aided in bone growth, boosted bone density and lessened fractures. (El-Hajj, 2004) Women receiving the drug showed a 6.8% increase in bone density. Women receiving a placebo had a 1.3% decrease. (Meunier, et. al, 2004). Half the increase in bone density (measured by x-ray densitometry) is attributed to the higher atomic weight of Sr compared with calcium, whereas the other half is assumed to be a true increase in bone mineral content. Strontium ranelate is registered for treatment of osteoporosis in Europe at a dose of 2 grams daily.
