Natriumhydrogencarbonat-Lösung Deltamedica (Sodium Hydrogen Carbonate)

Sodium hydrogen carbonate, the active ingredient in Natriumhydrogencarbonat-Lösung Deltamedica, is an electrolyte presented as a solution for injection for intravenous use. It helps correct metabolic acidosis and provides bicarbonate for electrolyte balance in adult and pediatric patients requiring intravenous therapy.

GNH USA supplies Natriumhydrogencarbonat-Lösung Deltamedica as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals worldwide. The company ensures quality compliance, meets EU pharmacopeial standards, and offers reliable global distribution for bulk procurement.

Sodium hydrogen carbonate is used intravenously to address disorders of acid‑base balance and electrolyte homeostasis.

- Metabolic acidosis: restores systemic pH by providing bicarbonate ions, aiding in the correction of acidemia. - Urine alkalinization: increases urinary bicarbonate concentration to raise urine pH for specific diagnostic or therapeutic purposes. - Electrolyte replacement in IV therapy: supplies bicarbonate as part of electrolyte solutions to maintain acid‑base equilibrium during intravenous fluid administration.

Intravenous sodium hydrogen carbonate may be associated with several adverse reactions, ranging from mild to severe.

Common Side Effects: - Hypernatremia: elevated serum sodium levels. - Metabolic alkalosis: excessive increase in blood pH. - Fluid overload: signs of volume expansion such as edema. - Local irritation: discomfort or phlebitis at the injection site.

Serious or Rare Side Effects: - Severe metabolic alkalosis: can lead to respiratory depression. - Pulmonary edema: accumulation of fluid in the lungs. - Anaphylactoid reaction: rare hypersensitivity response. - Cardiac arrhythmias: due to electrolyte disturbances.

Safe administration of sodium hydrogen carbonate requires attention to patient condition and handling practices.

- Monitor serum electrolytes: check sodium, potassium, and bicarbonate levels before and during therapy. - Assess arterial blood gases: evaluate pH and CO₂ status to guide dosing. - Use caution in renal impairment: reduced excretion may increase risk of alkalosis. - Avoid rapid infusion: administer over recommended time to prevent sudden pH shifts. - Adjust dose in heart failure: limit volume load to avoid fluid overload. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Sodium hydrogen carbonate can interact with other medications, affecting acid‑base balance or electrolyte status.

Major Interactions (Avoid): - Concurrent use with other alkalinizing agents (e.g., sodium citrate): may cause severe metabolic alkalosis. - Co‑administration with hypertonic saline solutions: increases risk of hypernatremia.

Moderate Interactions (Monitor Closely): - Combination with loop diuretics: may exacerbate hypokalemia. - Use with potassium‑sparing diuretics: can alter potassium balance. - Concomitant administration of drugs requiring an acidic environment (e.g., certain antibiotics): may reduce their efficacy. - Interaction with calcium channel blockers: monitor for changes in blood pressure due to volume shifts.
