Lactated Ringer’s Injection

Sodium Lactate Solution, the active ingredient in Lactated Ringer’s Injection, is an electrolyte solution presented as an injectable solution for intravenous use. It is used to restore extracellular fluid volume and electrolyte balance in patients with hypovolemia, during surgery, or after burns and trauma.

GNH USA supplies Lactated Ringer’s Injection as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals worldwide.

Lactated Ringer’s Injection is an electrolyte solution used in clinical situations that require rapid fluid and electrolyte replacement.

- Hypovolemia: restores circulating blood volume and corrects electrolyte deficits. - Intra‑operative care: maintains fluid and electrolyte balance throughout surgical procedures. - Burn and trauma care: provides essential ions and volume for tissue perfusion and metabolic support.

Adverse reactions may occur with any intravenous electrolyte solution.

Common Side Effects: - Mild hyperkalemia: transient elevation of serum potassium. - Local irritation: pain or erythema at the infusion site. - Mild metabolic alkalosis: due to lactate conversion. - Transient hypertension: from rapid volume expansion. - Nausea or vomiting: related to electrolyte shifts.

Serious or Rare Side Effects: - Severe hyperkalemia: can cause cardiac arrhythmias. - Hypercalcemia: may lead to neuromuscular symptoms. - Fluid overload: risk of pulmonary edema in susceptible patients. - Anaphylactoid reaction: rare but may present with hypotension and rash. - Electrolyte imbalance leading to renal dysfunction.

Lactated Ringer’s Injection should be administered with careful clinical monitoring.

- Assess volume status: evaluate signs of hypovolemia or overload before infusion. - Monitor electrolytes: check serum sodium, potassium, calcium, and chloride regularly. - Cardiac monitoring: required for patients at risk of arrhythmias. - Liver function: ensure adequate hepatic metabolism of lactate. - Contraindications: avoid in patients with severe hyperkalemia or hypercalcemia. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Lactated Ringer’s Injection can influence the pharmacodynamics of several co‑administered agents.

Major Interactions (Avoid): - Calcium channel blockers: may potentiate hypotensive effects. - Digoxin: increased risk of arrhythmias with electrolyte shifts. - Loop diuretics: can exacerbate electrolyte loss.

Moderate Interactions (Monitor Closely): - ACE inhibitors or ARBs: monitor blood pressure and renal function. - Insulin therapy: watch for changes in potassium levels. - Anticoagulants: volume expansion may affect hemodilution and clotting parameters.
