RESUMO
WHAT IS KNOWN AND OBJECTIVE: Carbaglu® or N-carbamylglutamate (NCG) is not recommended for administration in a vehicle other than water. We aim to report the use of breast milk (BM) as an alternative vehicle in a neonate rejecting NCG diluted in water. CASE SUMMARY: A neonate diagnosed with methylmalonic acidemia presented symptomatology of acidemia and hyperammonemia. After the patient refused oral NCG administration, a dissolution test was conducted in BM showing correct dissolution. The NCG-BM solution was tolerated and plasma ammonium concentrations remained within range in subsequent analytical controls. WHAT IS NEW AND CONCLUSION: BM as a vehicle for NCG is a safe and effective option for patients who refuse suspension in water and could lead to better treatment compliance in paediatric patients.
