| titleOfInvention | Piretanide polymorph, process for its preparation and its use |
| abstract | A piretanide polymorph having the following characteristics: a) an endothermic peak at about 132°C, b) an exothermic peak at about 143°C, and c) a melting peak at about 224°C in differential thermal curves; d) diffraction peaks (20) at 10.5, 12.2, 15.6, 19.1, 19.9, 22.0, 22.8, 25.6 and 30.6 in X-ray powder diffraction analysis; and e) characteristic absorption at around 1700 cm-1 and 3200-3500 cm-1 in infra-red absorption spectrum, and having a superior solubility around neutrality and a high bioavailability effective in the manner of oral or injection administration, which is prepared by dissolving piretanide in an aqueous solution of a base, adjusting a pH value of the solution to a pH range of less than 3.50 by an acid and recovering the precipitate thus separated, is described. |
