What is the process of adding water or another diluent to a commercially made drug bottle or vial to create a solution or suspension from a premade powder?

The process of adding water or another diluent to a commercially made drug bottle or vial to create a solution or suspension from a premade powder is referred to as reconstitution. This term specifically describes the action of transforming a solid form of medication back into a liquid suitable for administration.

Reconstitution is commonly performed with various types of medications that are supplied in powder form to enhance their stability and shelf-life, ensuring that they can be preserved until needed. Upon the addition of the appropriate diluent, the powder dissolves or suspends, allowing it to be administered effectively.

Other terms such as extramporaneous compounds relate to customized medicines made in a pharmacy, while a suppository refers to a form of medication intended for insertion into the body. An ampule is a sealed container used to hold medications, usually liquids, but does not specifically describe the action of adding a diluent or transforming powder into a usable form. Thus, the term reconstitute captures the process accurately.
