Résumé

Corticosteroids promote protein catabolism and can raise plasma ammonia. This may counteract the ammonia-lowering effect of glycerol phenylbutyrate in patients with urea cycle disorders and risk hyperammonemia.

Ce que signifie cette interaction, en termes simples

Glycerol phenylbutyrate and Methylprednisolone can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Glycerol phenylbutyrate belongs to Miscellaneous; Methylprednisolone belongs to Endocrine.

Niveau de preuve: Moderate

Pourquoi elle survient

Glucocorticoid-induced protein catabolism increases nitrogen load and ammonia production, opposing the nitrogen-scavenging effect.

Conduite à tenir

Monitor plasma ammonia closely when starting or changing corticosteroid therapy and adjust glycerol phenylbutyrate dosing as needed.
