nata0808 [166]

Reconstitution is the act of adding fluid such as distilled water to a powdered or crystalline form.

Additionally, medications are frequently provided in dry form, such as powders or crystals, which must be reconstituted with liquid before being injected parenterally. To create a specified liquid concentration, a dry ingredient is reconstituted by adding a liquid diluent. To ensure that the drug is reconstituted in the exact concentration, it is crucial to carefully follow the reconstitution instructions. The quantity of fluid used to dilute the drug must also be taken into account when determining the dosage of reconstituted medication to provide to the patient.
