L-Arginine L-glutamate Usage And Synthesis
Originator    Modamate,Abbott,US,1960
Uses    Intravenous ammonia detoxicant in cases of liver failure.
Manufacturing Process    This salt may be prepared by mixing L-arginine with L-glutamic acid in water and crystallizing the resulting salt from the water by the addition of a polar water miscible organic solvent to the water. For instance, when 17.2 g of Larginine and 14.5 g of L-glutamic acid were dissolved in 155 g of water, a clear homogeneous solution resulted which had a pH of 5.3. This solution was filtered and the filtrate was evaporated at 50°C under reduced pressure to a solution having a solids content of about 45%. Absolute methanol (220 g) was added to the concentrated solution of the salt and this mixture cooled to 5°C for one hour. The resulting solid salt was removed from the mixture by filtration and washed with absolute methanol. After being dried preliminarily in the air, the salt was further dried in a vacuum oven at 60°C for 3 hours. The resulting salt, L-arginine-L-glutamate, weighed 30 g (94.6% of the theoretically possible yield based on the amount of L-arginine and L-glutamic acid employed) and melted at 193-194.5°C with decomposition.
Brand name    Modumate (Abbott).
Therapeutic Function    Ammonia detoxicant (hepatic failure)
