Abstract
The characterization of poly(ethylene) glycol calcium citrate microsph eres is described. The calcium content and content uniformity of micro spheres, prepared at five concentrations ranging from 46.56 mu g/g to 81.49 mg/g, were determined by spectroscopy. Under sink conditions fir st-order in vitro dissolution kinetics were observed. Granules contain ing approximately SO mg Ca++/g PEG gave an in vitro calcium release ov er a 3-day period similar to that of a calcium hydroxide product, Pulp dent(R).
