Alka-Seltzer is a popular over-the-counter medication that is used to relieve various ailments, including heartburn, acid indigestion, and headaches. The active ingredients in Alka-Seltzer are aspirin, citric acid, and sodium bicarbonate.
Aspirin, also known as acetylsalicylic acid, is a non-steroidal anti-inflammatory drug (NSAID) that is used to reduce pain and inflammation. It works by inhibiting the production of prostaglandins, which are chemicals that contribute to inflammation and pain. Aspirin is also known to have blood-thinning properties, which can help to prevent the formation of blood clots.
Citric acid is a weak acid that is commonly found in citrus fruits. It is used in Alka-Seltzer to help neutralize excess stomach acid, which can cause heartburn and indigestion. Citric acid is also a natural preservative, which helps to extend the shelf life of the product.
Sodium bicarbonate, also known as baking soda, is a salt that is composed of sodium and bicarbonate ions. It is alkaline in nature, which means that it can neutralize acids. In Alka-Seltzer, sodium bicarbonate is used to neutralize excess stomach acid and provide relief from heartburn and indigestion. It is also used to provide a fizzing effect when the tablet is dissolved in water.
In addition to the active ingredients, Alka-Seltzer also contains a number of inactive ingredients, such as corn starch, lactose, and various food dyes and flavorings. These ingredients help to bind the active ingredients together, make the tablet easier to swallow, and improve the taste of the product.
Overall, the combination of aspirin, citric acid, and sodium bicarbonate in Alka-Seltzer makes it an effective medication for relieving a variety of ailments. However, it is important to follow the instructions on the label and consult a healthcare professional before taking Alka-Seltzer, as it may interact with certain medications and cause side effects in some people.
