Meglumine is an organic base used as a pH-adjusting agent and solubilizing agent in Solid orals and parenteral formulations. Many APIs gets rapidly ionized in the presence of acidic pH and which leads to decreased absorption. This problem can be overcome by using Meglumine i.e., as a basic agent which helps dissolve such APIs. Meglumine is manufactured with extreme precaution in our laboratory certified by EXCiPACT, ISO and GMP. We also provide robust regulatory documentation including Nitrosamine and elemental impurities risk assessment documents for pharma applications.


Meglumine is extensively used in the pharmaceutical industry for a variety of reasons:

  • Meglumine is an organic base used as a pH-adjusting agent
  • It is also used as a solubilizing agent in Solid orals and Parenteral formulations.

Stability and Storage Conditions

Observe standard precautions appropriate to the circumstances and quantity of material handled. Meglumine should be handled in a well-ventilated environment. Eye protection, gloves and a respirator are recommended while handling the material. Exposure to meglumine dust should be kept below 10 mg/m3 for total inhalable dust (8-hour TWA) or 5 mg/m3 for respirable dust (8-hour TWA). There is a risk of explosion when meglumine dust is mixed with air.

Safety and Handling Information

Keep away from heat and sources of ignition. Empty containers pose a fire risk; evaporate the residue under a fume hood. Ground all equipment containing material. Do not ingest. Do not breathe dust. Wear suitable protective clothing. In case of insufficient ventilation, wear appropriate respiratory equipment. If ingested, seek medical advice immediately and show the container or the label. Avoid contact with skin and eyes. Keep away from incompatibles such as oxidizing agents, moisture.
