Dextrose 10 and sodium chloride 0 45 in plastic container?

What does the “Dextrose 10 + Sodium Chloride 0.45” label mean?
The label indicates a 10 % (w/v) dextrose (glucose) solution mixed with 0.45 % (w/v) sodium chloride, packaged in a plastic IV bag. It is often written as D10 / 0.45 and provides 10 g of dextrose and 4.5 g of sodium chloride per liter.

When do clinicians choose this specific mix?
Because it is hypotonic and has a low osmolarity (~250 mOsm/kg), the solution is used when a patient needs a dextrose source but cannot tolerate isotonic or hypertonic fluids. It is common in pediatric or neonatal resuscitation, in patients with renal failure requiring glucose, or when a mild volume expansion is needed.

How does the combination influence glucose and electrolytes?
The dextrose raises plasma glucose, while the 0.45 % NaCl supplies sodium and chloride at half the concentration of normal saline. The resulting electrolyte balance is near hypotonic, which can help correct mild hyponatremia but may cause fluid shifts if given rapidly.

What patient groups should avoid D10 / 0.45?
Patients with uncontrolled diabetes, hyperglycemia, or impaired renal function are at risk of volume overload and elevated blood glucose. Because the solution is hypotonic, it is unsuitable for patients who require strict isotonic or hypertonic maintenance fluids.

Are there any special handling or labeling rules?
The plastic IV bag must be clearly labeled with the drug name, concentration, volume, and expiration date. It should be stored in a cool, dry place and protected from light if the manufacturer recommends it. Use within the stated shelf life.

Can D10 / 0.45 be used for long‑term IV therapy?
It is typically reserved for short‑term or intermittent use. For long‑term maintenance, isotonic solutions such as 0.9 % saline or balanced crystalloid solutions are preferred to avoid electrolyte imbalances.

Which companies produce D10 / 0.45 in plastic bags?
Major pharmaceutical suppliers of IV fluids (e.g., Baxter, Fresenius Kabi, Hospira) offer 10 % dextrose/0.45 % NaCl in standard plastic IV bags.

When does patent protection on this formulation expire?
Because the combination of dextrose and half‑normal saline is a generic formulation, patent protection is limited to proprietary manufacturing processes or packaging methods. Most generic versions have no active patent. For specific product patents, consult DrugPatentWatch.com.
