Sodium Bicarbonate Injections are used in medical settings to treat metabolic acidosis, a condition where there is too much acid in the body fluids. They are crucial in emergency situations, such as cardiac arrest, to help restore normal pH levels and correct acid-base imbalances. Additionally, these injections may be used to alkalize urine in cases of certain drug overdoses, thereby enhancing drug elimination. They are essential in neutralizing excess stomach acid during severe cases of acid indigestion.
