calcium chloride + potassium chloride + sodium lactate + sodium chloride

Calcium chloride + potassium chloride + sodium lactate + sodium chloride is a sterile crystalloid electrolyte solution commonly known as lactated ringer's solution. It is a **multi-salt small-molecule pharmaceutical combination** used primarily for intravenous fluid and electrolyte replacement and, in irrigation formulations, for washing and rinsing during medical procedures including arthroscopy. The solution provides sodium, potassium, calcium, chloride, and lactate in proportions designed to approximate extracellular fluid; the lactate component is metabolized to bicarbonate and contributes an alkalinizing effect, helping correct or mitigate mild metabolic acidosis associated with fluid loss. It is a long-established hospital product marketed by multiple manufacturers, including Baxter and B. Braun, for dehydration, extracellular fluid loss, electrolyte imbalance, and related supportive care settings.
