Multibic

Sodium hydrogen carbonate, the active ingredient in Multibic, is an excipient (electrolyte dialysis solution) presented as a solution for injection for haemodialysis and intravenous use. It provides bicarbonate buffering and electrolyte balance during renal replacement therapy in patients undergoing haemodialysis.

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

Multibic is used as an electrolyte and bicarbonate supplement in renal replacement therapy and related clinical settings. - Haemodialysis: restores sodium, chloride, calcium and magnesium levels while buffering acid‑base balance. - Acute metabolic acidosis during dialysis: supplies bicarbonate to correct pH. - Intravenous electrolyte repletion in renal failure: replaces lost electrolytes safely. - Adjunct to renal replacement therapy: supports overall fluid and electrolyte homeostasis.

Multibic may be associated with a range of adverse reactions, most of which are related to its electrolyte composition.

Common Side Effects: - Mild hypernatremia: transient elevation of serum sodium. - Transient hyperchloremia: increased chloride levels. - Mild hypermagnesemia: elevated magnesium concentration. - Mild hypercalcemia: raised calcium levels. - Local irritation at infusion site. - Nausea or mild gastrointestinal discomfort.

Serious or Rare Side Effects: - Severe electrolyte imbalance leading to cardiac arrhythmia. - Metabolic alkalosis from excess bicarbonate. - Hypotension due to rapid infusion. - Allergic reaction or anaphylaxis. - Pulmonary edema from fluid overload. - Hemolysis in patients with incompatible solutions.

When using Multibic, clinicians should consider patient-specific factors and monitor relevant parameters. - Renal function: assess baseline electrolytes and acid‑base status. - Cardiac history: watch for arrhythmias in patients with pre‑existing conduction disorders. - Fluid balance: avoid rapid large-volume infusions in patients at risk of overload. - Concomitant electrolyte therapies: adjust doses to prevent cumulative excess. - Pregnancy and lactation: use only if clearly needed, as safety data are limited. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze.

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

Major Interactions (Avoid): - High‑dose bicarbonate agents: risk of severe metabolic alkalosis. - Calcium channel blockers combined with high calcium loads: potential hypercalcemia. - Magnesium‑containing laxatives or antacids: may cause dangerous hypermagnesemia.

Moderate Interactions (Monitor Closely): - Loop diuretics: may exacerbate electrolyte shifts. - ACE inhibitors or ARBs: monitor potassium and renal function. - NSAIDs: can affect renal perfusion and electrolyte handling. - Blood transfusions: watch for citrate‑related calcium changes.
