Sodium Chloride 0.45% (Half Normal Saline)Third Party Manufacturing in India

Sodium Chloride 0.45% (Half Normal Saline) is a hypotonic crystalloid solution that provides free water and electrolytes to the body in a lower sodium concentration than standard normal saline. The solution contains 77 mEq/L each of sodium and chloride, producing an osmolality of approximately 154 mOsm/L, which is roughly half that of human plasma. When infused intravenously, the hypotonic nature of the solution means that after accounting for the sodium chloride content, the remaining free water distributes across both the extracellular and intracellular compartments. This makes half normal saline particularly useful for providing maintenance fluid requirements while simultaneously correcting intracellular dehydration. The hypotonicity allows water to move into the intracellular space to rehydrate cells, which is different from isotonic solutions that primarily stay in the extracellular compartment. The lower sodium content also reduces the total sodium load delivered to the patient, which can be beneficial in patients with elevated serum sodium levels or those at risk of fluid overload. Overly rapid administration of hypotonic fluids can cause hyponatremia due to dilutional effects, so half normal saline is typically used cautiously and is rarely used for rapid volume resuscitation where isotonic fluids are preferred. Its primary role is in maintenance therapy and in conditions where both water and moderate electrolyte replacement is needed without the full sodium load of 0.9% saline.

Therapeutic Uses

Sodium Chloride 0.45% Infusion is prescribed for:

• Maintenance Fluid Therapy: Daily fluid and electrolyte maintenance in patients who require ongoing IV fluid support but do not need acute volume resuscitation.
• Hypernatremia: Correction of elevated serum sodium levels by providing free water along with controlled sodium replacement.
• Gastrointestinal Fluid Loss Replacement: Replacement of hypotonic fluid losses from diarrhea, vomiting, and nasogastric suctioning.
• Pediatric Fluid Management: Maintenance hydration in children where lower sodium concentration is appropriate to match daily requirements.
• Diuretic Therapy Adjunctive: Fluid replacement in patients on thiazide or loop diuretics where less sodium loading is desired.
• Post-operative Recovery: Hydration in the postoperative period where plasma sodium levels are within or above normal range.

Why Manufacturers Choose Sodium Chloride 0.45%

Half normal saline complements a manufacturer's IV fluid portfolio by offering a hypotonic option for patients who do not need the full sodium load of 0.9% saline. While lower in total volume than normal saline, it is an essential product for hospitals with specialized departments including pediatrics, nephrology, and endocrinology. Indian LVP manufacturers with WHO-GMP certification can produce 0.45% saline as a companion product to their normal saline line, using the same production infrastructure. It is commonly packed in 100ml, 250ml, and 500ml infusion bottles. Sodium Chloride 0.45% third party manufacturing in India serves both the PCD franchise market and export markets where balanced fluid lines are valued for comprehensive hospital supply contracts.
