Résumé

Barbiturates and benzodiazepines add together to cause profound sedation and respiratory depression. Amobarbital also induces hepatic enzymes and may lower diazepam levels over time, making the net effect unpredictable.

Ce que signifie cette interaction, en termes simples

Amobarbital and Diazepam 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.

Amobarbital belongs to Central Nervous System; Diazepam belongs to Musculoskeletal.

Niveau de preuve: Moderate

Pourquoi elle survient

Additive GABA-A mediated CNS depression, with CYP3A4 and CYP2C19 induction by amobarbital reducing diazepam exposure.
