DOCUMENT TYPE: Journal CA Section: 1 (Pharmacology) Section cross-reference(s): 22, 23, 27 The effect of trifluoroetidronic acid (I) on the inhibition of hydroxyapatite (II) pptn. from a soln. of calcium salt and phosphate was compared with etidronic acid (III). At low drug concns., both compds. exhibited comparable activities as measured by the Ca concn. At higher drug concns., I was more effective than III. This apparently low activity of III was due to relatively low soly. of its Ca salt. Conversely, I was more effective in preventing II pptn. because even at higher concns., its Ca salt remained sol. Both compds. significantly inhibited II dissoln. The crystal structure of the hydrolysis product of I was detd.Except for chemicals metioned above, 354-32-5 and 2809-21-4 are also used. .
