Beschreibung
Zusammenfassung:	Crystal D or E of 1-hydroxy-2-(imidazo[1,2-a]-pyridin-3-yl)ethane-1,1-bis(phosphonic acid) monohydrate having specified lattice spacing and relative intensity in the powder X-ray diffraction spectrum obtained by using Cu-K alpha radiation and a dehydration peak temperature of 135-149 DEG C or 160-170 DEG C according to TG-DSC thermogravimetric analysis; and a solid pharmaceutical preparation containing the same. The crystals are useful for producing a stable solid preparation of the above compound which has an excellent drug efficacy for diseases wherein increased bone resorption participates, such as osteoporosis.
