Summary
Both drugs are benzodiazepines that enhance GABA-A activity, so combined use produces additive sedation and respiratory depression. Profound sedation, hypoventilation and loss of airway control can occur, particularly during procedural sedation.
What this interaction means in plain words
Diazepam and Remimazolam 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.
Diazepam belongs to Musculoskeletal; Remimazolam belongs to Central Nervous System.
Why it happens
Additive pharmacodynamic CNS and respiratory depression through GABA-A receptor potentiation.
What to do
Titrate remimazolam carefully using a reduced dose and monitor oxygen saturation, respiratory rate and level of consciousness continuously through recovery. Ensure airway equipment and a reversal agent such as flumazenil are available.
What to ask your pharmacist
