excipient in cosmetics and X-ray contrast media
|
Definition
|
ChEBI: A hexosamine that is D-glucitol in which the hydroxy group at position 1 is substituted by the nitrogen of a methylamino group. A crystalline base, it is used in preparing salts of certain acids for use as diagnostic radiopaque media, whi e its antimonate is used as an antiprotozoal in the treatment of leishmaniasis.
|
Production Methods
|
Meglumine is prepared by the imination of glucose and monomethylamine, in an alcoholic solution, followed by catalytic hydrogenation.
|
Brand name
|
Renovue (Bracco).
|
Pharmaceutical Applications
|
Meglumine is an organic base used as a pH-adjusting agent and solubilizing agent, primarily in the preparation of soluble salts of iodinated organic acids used as X-ray contrast media.
|
Safety
|
Meglumine is widely used in parenteral pharmaceutical formulations and is generally regarded as a nontoxic material at the levels usually employed as an excipient.

|
storage
|
Meglumine does not polymerize or dehydrate unless heated above 150°C for prolonged periods.
The bulk material should be stored in a well-closed container in a cool, dry place. Meglumine should not be stored in aluminum containers since it reacts to evolve hydrog en gas; it discolors if stored in containers made from copper or copper alloys. Stainless steel containers are recommended.
|
Purification Methods
|
Crystallise N-methyl-D(-)-glucamine from MeOH. Its solubility in H2O is 10%. [Karrer & Herkenrath Helv Chim Acta 20 83 1957 also for other N-alkyl derivatives, Beilstein 4 IV 1914.]
|
Incompatibilities
|
Incompatible with aluminum, copper, mineral acids, and oxidizing materials. Differential scanning calorimetry studies suggest meglumine is incompatible with glipizide.
|
Regulatory Status
|
Included in the FDA Inactive Ingredients Database (injections; oral tablets). Included in parenteral medicines licensed in the UK.
