Droperidol is safe and effective for the treatment of severely agitated patients in the ED [1-3]. But what about its use for agitation in elderly patients specifically?
Two Australian studies evaluated droperidol in more than 200 older adults (≥ 65 years old) in the prehospital and ED settings [4,5]. Both studies found droperidol to be effective in elderly patients with acute behavioral disturbances. The median time to sedation was ~20-30 minutes with doses ranging from 2.5-10 mg (Table 1).
|Characteristic||Page, et al (n=162)||Calver, et al (n=47)|
|Median Age||78 years||81 years|
|Initial Droperidol IM Dose||5 mg||10 mg (n=30)|
5 mg (n=15)
2.5 mg (n=2)
|Median Time to Sedation||19 mins||10 mg: 30 mins|
5 mg: 21 mins
2.5 mg: NA
|Patients Sedated with ≤ 10 mg Droperidol||144 (89%)||34 (72%)|

Additionally, each study broke down each time a patient experienced an adverse event (Table 2). Overall, these adverse events were uncommon (4.5%), mild in nature, and resolved spontaneously or with minor interventions. No patients developed Torsades de Pointes.
|Study||Age/Sex||Droperidol Dose||Adverse Events||Management||Time Post-Droperidol|
|Page, et al (n=162)||76 yo Male||5 mg||SBP <90 (88/54)||Spontaneous Resolution||–|
|87 yo Female||10 mg||SBP <90 (80/46)||Spontaneous Resolution||–|

|86 yo Male||5 mg||O2 sat <90% (88%)||Supplemental Oxygen||–|
|Calver, et al (n=49)||75 yo Male||10 mg||SBP <90||–||30 mins|
|68 yo Female||10 mg||SBP <90||–||5 mins|
|73 yo Male||10 mg||Airway Obstruction||–||100 mins|
|87 yo Female||2.5 mg||Oversedation||–||480 mins|
Table 2: Safety of droperidol in older adults
Taking the above points into account, droperidol appears to be both effective and safe in agitated adults ≥ 65 years of age for the treatment of agitation. The study authors recommend starting with 5 mg and repeating, if necessary, rather than initially using a dose of 10 mg.
