pH
Osmolality
The osmolality of droperidol 2.5 mg/mL was determined to be 16 mOsm/kg.1233
Intact ampuls and vials of droperidol should be stored at controlled room temperature and retained in the original container to protect from light.2906; 2907
Precipitation may occur if droperidol is mixed with barbiturates.4
Syringes
The stability of droperidol 2.5 mg/mL repackaged in polypropylene syringes was evaluated. Little change in concentration was found after 4 weeks at room temperature out of direct light.2164
Central Venous Catheter
Droperidol (Abbott) 0.4 mg/mL in dextrose 5% was found to be compatible with the ARROWg+ard Blue Plus (Arrow International) chlorhexidine-bearing triple-lumen central catheter. Essentially complete delivery of the drug was found with little or no drug loss occurring. Furthermore, chlorhexidine delivered from the catheter remained at trace amounts with no substantial increase due to the delivery of the drug through the catheter.2335
