NAGS Deficiency Patients

CARBAGLU® (carglumic acid) tablets for oral suspension 200mg should be initiated as soon as the diagnosis of NAGS deficiency is suspected, which may be as soon as at birth, and managed by a physician and medical team experienced in metabolic disorders 1

Patients should understand the importance of taking CARBAGLU exactly as prescribed—the right dose at the right time—to ensure a constant amount of medicine in their bodies.

Dosage for Acute Hyperammonemia due to NAGS Deficiency:1

  1. The recommended pediatric and adult dosage is 100mg/kg/day to 250 mg/kg/day.
  2. Divide the daily dosage into 2 to 4 doses and round to the nearest 100 mg (i.e., half of a CARBAGLU tablet).
  3. During acute hyperammonemic episodes, administer CARBAGLU with other ammonia lowering therapies, such as alternate pathway medications, hemodialysis, and protein restriction.

 

Dosage for Chronic Hyperammonemia due to NAGS Deficiency:1

  1. The recommended pediatric and adult maintenance dosage is 10 mg/kg/day to 100mg/kg/day.
  2. Divide the daily dosage into 2 to 4 doses and round to the nearest 100 mg (i.e., half of a CARBAGLU tablet).
  3. During maintenance therapy, the concomitant use of other ammonia lowering therapies and protein restriction may be needed based on plasma ammonia levels.Closely monitor plasma ammonia levels. Titrate the CARBAGLU dosage to maintain the plasma ammonia level within the normal range for the patient’s age, taking into consideration their clinical condition (e.g., nutritional requirements, protein intake, growth parameters, etc.).
