The ADD-Vantage^® System consists of two components, the specially designed diluent container and drug vial. ADD-Vantage^® keeps drug and diluent separate until the system is activated, just prior to intravenous administration. Drugs can be prepared quickly without needles, syringes or alcohol swabs. Liquid or powdered medications are provided in a threaded vial that mates with the top of flexible diluent bags in 50, 100 or 250 mL sizes. All ADD-Vantage^® vials are glass, encased in a plastic shroud.
