Ives RL Injection is an isotonic intravenous fluid formulation containing Sodium Chloride (0.8% w/v), Sodium Lactate (0.24% w/v), Potassium Chloride (0.04% w/v), and Calcium Chloride (0.027% w/v). This balanced electrolyte solution is designed to restore and maintain fluid and electrolyte balance in patients experiencing dehydration, electrolyte imbalances, or metabolic acidosis. The sodium chloride component provides essential sodium and chloride ions necessary for maintaining osmotic equilibrium and extracellular fluid volume. Sodium lactate serves as a buffer, metabolizing to bicarbonate in the liver, thereby assisting in the correction of metabolic acidosis. Potassium chloride replenishes potassium levels, critical for normal cellular function, nerve conduction, and muscle contraction. Calcium chloride supplies calcium ions, essential for cardiac function, blood coagulation, and neuromuscular activity. Ives RL Injection is indicated for use in conditions such as fluid loss due to surgery, trauma, burns, or gastrointestinal disturbances. It should be administered under strict medical supervision with appropriate monitoring of electrolyte levels and acid-base status to avoid complications such as hyperkalemia, hypercalcemia, or fluid overload. This solution is contraindicated in patients with hyperkalemia, hypercalcemia, or severe renal impairment. Proper aseptic technique is essential during administration to prevent infection.
