摘要
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.
用白話說明這項交互作用的意義
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.
為什麼會發生
Additive GABA-A mediated CNS depression, with CYP3A4 and CYP2C19 induction by amobarbital reducing diazepam exposure.
處置方式
Avoid the combination where possible; otherwise use the lowest doses with close monitoring of sedation and respiration. Reassess diazepam response when the barbiturate is started or stopped.
