Résumé

Corticosteroids promote protein breakdown and can raise plasma ammonia, which counteracts the ammonia-lowering goal of glycerol phenylbutyrate in urea cycle disorders. This may risk hyperammonemia.

Ce que signifie cette interaction, en termes simples

Fludrocortisone and Glycerol phenylbutyrate 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.

Fludrocortisone belongs to Endocrine; Glycerol phenylbutyrate belongs to Miscellaneous.

Niveau de preuve: Low

Pourquoi elle survient

Corticosteroid-driven protein catabolism increases nitrogen load and ammonia production, opposing the nitrogen scavenging effect.

Conduite à tenir

Monitor plasma ammonia closely when fludrocortisone is started or adjusted, and adjust the glycerol phenylbutyrate dose or protein intake as needed.
