Multibic

Sodium hydrogen carbonate, the active ingredient in Multibic, is an electrolyte component presented as an intravenous solution for haemodialysis use. It helps correct acid‑base balance and replenish electrolytes in patients undergoing dialysis, alongside magnesium chloride, sodium chloride and calcium chloride which together support electrolyte homeostasis.

GNH USA supplies Multibic as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals and dialysis centres worldwide.

Multibic is used as an intravenous electrolyte and buffer solution during haemodialysis and related renal replacement therapies.

- Metabolic acidosis: provides bicarbonate to raise blood pH and correct acidemia. - Electrolyte imbalance: restores sodium, chloride, calcium and magnesium concentrations lost during dialysis. - Calcium supplementation: supplies calcium ions to support cardiac contractility and neuromuscular function in dialysis patients.

Multibic may be associated with electrolyte‑related adverse reactions and infusion‑related events.

Common Side Effects: - Hypernatremia: elevated serum sodium levels. - Hypercalcemia: increased calcium concentration. - Hypermagnesemia: raised magnesium levels. - Fluid overload: excess extracellular fluid volume. - Hypotension: drop in blood pressure during infusion. - Local irritation at infusion site.

Serious or Rare Side Effects: - Severe electrolyte disturbances leading to cardiac arrhythmia. - Pulmonary edema from fluid overload. - Anaphylactic or severe hypersensitivity reaction. - Metabolic alkalosis from excessive bicarbonate. - Thrombophlebitis at the catheter site. - Acute kidney injury exacerbation.

When using Multibic, clinicians should observe specific safety measures.

- Electrolyte monitoring: regularly check serum sodium, calcium, magnesium and bicarbonate levels. - Fluid balance: assess patient’s volume status to avoid overload. - Cardiac monitoring: observe for arrhythmias in patients with electrolyte shifts. - Contraindications: avoid in patients with known severe hypercalcemia or hypermagnesemia. - Compatibility: ensure solution compatibility with other IV fluids and medications. - Store at ambient temperature: keep in original container, protect from direct sunlight and moisture.

Multibic can interact with other agents that affect electrolyte balance or acid‑base status.

Major Interactions (Avoid): - Calcium channel blockers: may potentiate hypercalcemia. - Magnesium‑containing laxatives or antacids: increase risk of hypermagnesemia. - High‑dose sodium bicarbonate: can cause severe metabolic alkalosis.

Moderate Interactions (Monitor Closely): - Loop diuretics: may exacerbate electrolyte shifts. - ACE inhibitors or ARBs: influence potassium and sodium handling. - Other intravenous electrolyte solutions: risk of cumulative overload. - Blood transfusions: may affect calcium levels.
