Process for the preparation of high purity levosimendan |
| abstract |
An improved process for the preparation of high purity Levosimendan includes treatment of Levosimendan crude with an organic acid, adding an organic acid to precipitate Levosimendan and isolating pure Levosimendan from the precipitate. Levosimendan obtained by the improved process is pharmaceutically acceptable with no impurity higher than 0.2 percent. |
