Kalium Chloratum Léciva (Potassium Chloride)

Kalium Chloratum Léciva is used in the electrolyte replacement pathway to correct low serum potassium levels.

• Hypokalemia: restores normal serum potassium concentrations and supports cellular function.
• Intravenous potassium supplementation: provides controlled potassium delivery during IV therapy to prevent deficiency.
• Perioperative electrolyte management: maintains potassium balance in patients undergoing surgery or intensive care.

• Potassium chloride dissociates in plasma to release potassium ions, raising extracellular potassium concentration. The increased serum potassium re‑establishes the normal electrochemical gradient across cell membranes, supporting membrane potential, nerve impulse transmission, and muscle contraction, thereby correcting hypokalemia.

Potassium chloride injection may be associated with adverse reactions, ranging from mild to severe.

Common Side Effects

• Injection site pain: mild discomfort at the infusion site.
• Phlebitis: inflammation of the vein used for administration.
• Nausea: transient feeling of queasiness.
• Vomiting: occasional emesis following infusion.
• Hyperkalemia: mild elevation of serum potassium if dosing exceeds needs.

Serious or Rare Side Effects

• Cardiac arrhythmia: potentially life‑threatening rhythm disturbances.
• Severe hyperkalemia: marked increase in serum potassium leading to muscle weakness or paralysis.
• Anaphylactic reaction: rare hypersensitivity with rash, bronchospasm, or hypotension.
• Metabolic acidosis: uncommon disturbance of acid‑base balance.
• Tissue necrosis: rare if extravasation occurs.

When using Kalium Chloratum Léciva, clinicians should observe several precautions to minimize risk.

• Renal impairment: assess kidney function before administration.
• Cardiac disease: monitor ECG in patients with existing arrhythmias.
• Concomitant potassium‑sparing drugs: avoid additive hyperkalemia.
• Rapid infusion: limit infusion rate to prevent cardiac events.
• Serum potassium monitoring: check levels before and after dosing.
• Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Potassium chloride can interact with several medicines, altering potassium balance or cardiac risk.

Major Interactions (Avoid)

• ACE inhibitors or ARBs: may cause dangerous hyperkalemia.
• Potassium‑sparing diuretics (e.g., spironolactone): increase risk of severe hyperkalemia.
• NSAIDs: can reduce renal potassium excretion, raising serum levels.

Moderate Interactions (Monitor Closely)

• Digoxin: elevated potassium can enhance digoxin toxicity.
• Beta‑blockers: may mask hypokalemia symptoms.
• Insulin or glucose therapy: shifts potassium intracellularly, affecting serum measurements.
