Which of these is an example of an antacid?

Mylanta is an example of an antacid because it contains ingredients that neutralize stomach acid, providing relief from symptoms of heartburn, indigestion, and upset stomach. Antacids typically work by raising the pH level in the stomach, which can help alleviate discomfort caused by excess acidity. Mylanta, specifically, contains aluminum hydroxide and magnesium hydroxide, both of which are common antacid components that help to reduce the acidity in the stomach.

In contrast, Nelatin is not classified as an antacid; it is more commonly associated with various gastrointestinal treatments. Phenytoin is an anticonvulsant medication used primarily for epilepsy and does not function as an antacid. Amoxicillin is an antibiotic effective against bacterial infections, and it has no role in neutralizing stomach acid. Understanding the classifications of these medications is essential for determining their appropriate uses in a pharmacy setting.
