Sodium chloride is an electrolyte supplement. Sodium and chloride are important electrolytes in the body, mainly existing in extracellular fluid, and play a very important role in maintaining normal blood and extracellular fluid volume and osmotic pressure.

It produces direct pharmacological effects through hypertonic dehydration, eliminating cerebral edema and reducing intracranial pressure; it plays an osmotic diuretic role; tissue dehydration effect: increases plasma osmotic pressure, reduces tissue edema, reduces intraocular pressure, intracranial pressure and cerebrospinal fluid volume and pressure; diuretic effect: increases blood volume, dilates renal blood vessels, increases renal blood flow, and reduces the reabsorption of water and electrolytes by the renal tubules.

It produces direct pharmacological effects through hypertonic dehydration, eliminating cerebral edema and reducing intracranial pressure; 1g of mannitol can produce an osmotic concentration of 5.5mOsm, and injection of 100g of mannitol can transfer 2000ml of intracellular water to the extracellular space and excrete 50g of urinary sodium; it increases blood volume and promotes the secretion of prostaglandin I2, dilates renal blood vessels, increases renal blood flow and glomerular filtration rate; very little is reabsorbed by the renal tubules, which increases the osmotic concentration of the tubular fluid and reduces the reabsorption of water and electrolytes.

1. Treat metabolic acidosis. This product increases the concentration of carbonate in plasma and neutralizes hydrogen ions, thereby correcting acidosis. 2. Alkalinize urine. As the pH value increases after the concentration of bicarbonate in urine increases, uric acid, sulfonamide drugs and hemoglobin are not easy to form crystals or aggregate in urine. 3. Antacid. Oral administration can quickly neutralize or buffer gastric acid without directly affecting gastric acid secretion. Therefore, the pH in the stomach increases rapidly to relieve the symptoms caused by high gastric acid.
