Pharmacodynamic Properties

5.1   Pharmacodynamic properties
Pharmacotherapeutic group “Electrolytes with carbohydrates”,
ATC code: “B05BB02”.


Sodium Chloride 0.3 % and Glucose 3.3% Solution for Infusion Baxter is a hypotonic and iso- osmolar solution of sodium chloride and glucose.

The pharmacodynamic properties of Sodium Chloride 0.3 % and Glucose 3.3% Solution for Infusion Baxter are those of its components (sodium chloride and glucose).
Ions, such as sodium, circulate through the cell membrane, using various mechanisms of transport, among which is the sodium pump (Na+/K+-ATPase). Sodium plays an important role in neurotransmission and cardiac electrophysiology, and also in its renal metabolism.

Chloride is mainly an extracellular anion. Intracellular chloride is in high concentration in red blood cells and gastric mucosa. Re-absorption of chloride follows re-absorption of sodium.
Glucose is the principal source of energy in cellular metabolism. The glucose in this solution provides a caloric intake of 132 kcal/l.

Pharmacokinetic Properties

5.2     Pharmacokinetic properties
The pharmacokinetic properties of this solution are those of its components (sodium, chloride and glucose).
After injection of radiosodium (24Na), the half -life is 11 to 13 days for 99% of the injected Na and one year for the remaining 1%. The distribution varies according to tissues: it is fast in muscles, liver, kidney, cartilage and skin; it is slow in erythrocytes and neurones; it is very slow in the bone. Sodium is predominantly excreted by the kidneys, but (as described earlier) there is extensive renal re-absorption. Small amounts of sodium are lost in the faeces and sweat.
The two main metabolic pathways of glucose are gluconeogenesis (energy storage) and glycogenolysis (energy release). Glucose metabolism is regulated by insulin.
