Résumé

Corticosteroids promote protein catabolism and can raise ammonia, working against the ammonia-lowering aim of glycerol phenylbutyrate in urea cycle disorders. This can precipitate hyperammonemia.

Ce que signifie cette interaction, en termes simples

Dexamethasone and Glycerol phenylbutyrate can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Dexamethasone belongs to Endocrine; Glycerol phenylbutyrate belongs to Miscellaneous.

Niveau de preuve: Moderate

Pourquoi elle survient

Glucocorticoid-induced protein breakdown increases nitrogen load and plasma ammonia, opposing the nitrogen scavenging action.

Conduite à tenir

Monitor plasma ammonia closely and adjust the glycerol phenylbutyrate dose or protein intake if ammonia rises; avoid unnecessary steroid use.
