If you have eaten too much salt and need to get rid of it quickly, the best way is to apply furosemide injection intravenously. Furosemide injection, also known as tachycardia injection, has a strong electrolyte excretion effect and enhances the excretion of chloride and sodium ions. The main component of salt is sodium chloride, furosemide can act on the posterior wall segment of the ascending branch of the medullary collaterals of the renal tubule, and the posterior wall segment of the medullary collaterals is the main part of the reabsorption of sodium ions and chloride ions, which can be effectively inhibited, so that the osmotic pressure gradient of the crystal is lowered, and the concentrating function of the renal tubule decreases, which ultimately leads to the increase in the excretion of sodium ions and chloride ions, and the reduction of reabsorption, and thus plays a role in the rapid excretion of sodium chloride from the body.
