  • Process for the preparation of gadobenate dimeglumine complex in a solid form
    Patent number: 9795695
    Abstract: The present invention discloses a process for the preparation of gadobenate dimeglumine complex in a solid form. In particular, said solid form is conveniently obtained by spray-drying a corresponding liquid suspension at a given temperature and concentration. The present invention is particularly advantageous for the industrial scale as the solid form may be obtained by employing water as a solvent, which is a non-toxic solvent, easy to handle and basically not requiring troublesome health or safety precautions.
