Mechanism of action

D5W is a hypotonic crystalloid solution that delivers dextrose (glucose) and water intravenously. The dextrose is metabolized for energy and the water distributes across intracellular and extracellular compartments, providing both modest caloric support and free water for rehydration. It is commonly used for maintenance fluid therapy and to prevent dehydration in hospitalized patients.
