Tác dụng
Description:
Mechanism of Action: Carglumic acid is a synthetic structural analogue of N-acetylglutamate (NAG). It is used to treat patients w/ deficiency in N-acetylglutamate synthase (NAGS), a mitochondrial enzyme which produces NAG to activate carbamoyl phosphate synthetase (CPS). Thus, it restores the activity of the urea cycle, reducing plasma ammonia concentrations to normal levels. Pharmacokinetics: Absorption: Time to peak plasma concentration: 3 hr. Distribution: Volume of distribution: Approx 2,657 L. Metabolism: Metabolised by intestinal flora to CO2. Excretion: Via faeces (≤60% as unchanged drug), urine (9% as unchanged drug), and lungs (as CO2). Elimination half-life: 4.3-9.5 hr. |
