Hydroxypatite-polysaccharide granules for drug delivery.

The formation of hydroxyapatite by co-precipitation from sodium alginate and sodium carboxymethylcellulose aqueous solutions with the use of dibasic calcium phosphate dihydrate and calcium hydroxide as starting reagents is studied. A technique to prepare the hydroxyapatite/polysaccharide (micro)granules is developed. An introduction of an antimicrobial Biocide 1 agent in proper amount into the granules is provided, and the behavior of the granules is evaluated.
