Alkalinizing agents are used to treat conditions with increased acid, like heartburn. They also have other uses, such as managing gout and kidney stones. These medications work by neutralizing excess acid in your body. Alkalinizing agents come in different forms, including oral tablets and liquids. Examples include sodium bicarbonate, calcium carbonate (Tums), and potassium citrate / sodium citrate / citric acid (Tricitrates). You can choose the form that best fits your needs.
