What are parenteral medications or additives prepared in appropriate diluent for administration called?

The term used for parenteral medications or additives that are prepared in an appropriate diluent for administration is "premixed bags/bottles." This designation indicates that the medication has already been combined with the diluent in a ready-to-use format, which enhances convenience and safety for administration to patients.

Premixed bags or bottles eliminate the need for additional preparation by the healthcare provider at the point of care, thereby reducing the risk of contamination and dosing errors. These products are often used in clinical settings where time efficiency and sterility are paramount, particularly in situations where immediate administration is necessary, such as in emergency care or intravenous therapy.

In contrast, while IV mixtures and bulk solutions may also refer to liquid medications intended for infusion, they do not necessarily imply that these preparations are ready for immediate use without further manipulation. Suspensions are a different category altogether, as they refer to a heterogeneous mixture in which solid particles are dispersed within a liquid, rather than a stable, fully dissolved solution ready for administration.
