Natriumhydrogencarbonat-Lösung (Sodium Hydrogen Carbonate)

Sodium hydrogen carbonate, the active ingredient in Natriumhydrogencarbonat-Lösung, is an alkali/antacid presented as a solution for injection for intravenous use. It is employed to correct metabolic acidosis and other acid‑base disturbances in hospitalized patients.

GNH USA supplies Natriumhydrogencarbonat-Lösung as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals worldwide.

Sodium hydrogen carbonate solution acts on systemic acid‑base balance and is indicated for the following conditions:

- Metabolic acidosis: restores normal plasma pH by providing bicarbonate ions. - Acid‑base disturbances: buffers excess hydrogen ions to correct pH abnormalities. - Hyperkalemia (adjunct therapy): promotes intracellular shift of potassium while correcting acidosis.

Sodium hydrogen carbonate injection may be associated with several adverse reactions.

Common Side Effects: - Hypernatremia: elevated serum sodium levels. - Fluid overload: excess extracellular fluid volume. - Metabolic alkalosis: over‑correction of pH. - Hypocalcemia: reduced ionized calcium. - Hypokalemia: lowered serum potassium. - Local irritation at IV site: redness or discomfort.

Serious or Rare Side Effects: - Severe metabolic alkalosis: can lead to seizures or cardiac arrhythmias. - Pulmonary edema: accumulation of fluid in the lungs. - Cardiac arrhythmias: due to electrolyte shifts. - Severe hypernatremia: neurologic impairment. - Hypersensitivity reactions: rash, urticaria, or anaphylaxis. - Thrombophlebitis: inflammation of veins at the infusion site.

When using sodium hydrogen carbonate solution, clinicians should observe the following precautions:

- Monitor serum electrolytes: regularly check sodium, potassium, calcium, and bicarbonate levels. - Adjust infusion rate: avoid rapid administration that may cause over‑correction. - Assess acid‑base status: perform frequent blood‑gas analyses. - Use caution in renal impairment: reduced bicarbonate excretion may increase risk of alkalosis. - Contraindicated in severe metabolic alkalosis: do not administer. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Sodium hydrogen carbonate may interact with other medications that affect acid‑base balance or electrolyte homeostasis.

Major Interactions (Avoid): - Oral sodium bicarbonate: additive alkalinizing effect. - Carbonic anhydrase inhibitors (e.g., acetazolamide): risk of severe alkalosis. - High‑dose potassium supplements: may blunt intended potassium shift.

Moderate Interactions (Monitor Closely): - Loop diuretics (e.g., furosemide): can exacerbate electrolyte disturbances. - ACE inhibitors or ARBs: monitor potassium and acid‑base status. - NSAIDs: may affect renal handling of bicarbonate and electrolytes.
