Active ingredients in A16AA05

Active Ingredient Description
Carglumic acid

Carglumic acid is a carbamoyl phosphate synthetase 1 (CPS 1) allosteric modulator. CPS1 is found in the mitochondria and is the first enzyme of the urea cycle, which converts ammonia into urea. Carglumic acid acts as a replacement for N-acetylglutamate (NAG) in N-acetylglutamate synthase (NAGS) deficiency patients by activating CPS1 but it does not help to regulate the urea cycle. Carglumic acid indicated as adjunctive therapy for the treatment of acute hyperammonemia due to the deficiency of the hepatic enzyme NAGS.
