摘要

The intercalation of 1-hydroxyethylidene-1,1-diphosphonic acid (HEDP), which is a drug for osteoporosis, in layered double hydroxide (LDH) was examined with the goal of developing a novel drug delivery system (DDS) of HEDP. To prevent side reactions, the intercalation reaction was carried out at 0 degrees C, and at pH 4-6. The uptake of HEDP was determined as 3.5 mmol g(-1) of LDH, and the interlayer distance increased from 7.8 to 13 A. The HEDP-release profiles into K(2)CO(3) aqueous solution and into various buffer solutions were also examined.
