Which medications fall under the category of antacids?

• A. Guaifenesin, omeprazole
• B. Aluminum hydroxide, magnesium hydroxide
• C. Dextromethorphan, codeine
• D. Famotidine, ranitidine

Answer: (B)

Antacids are medications specifically designed to neutralize stomach acid and provide relief from conditions such as heartburn, indigestion, and gastroesophageal reflux disease (GERD). The choice that includes aluminum hydroxide and magnesium hydroxide represents two common types of antacids. Aluminum hydroxide acts by providing a buffering effect, reducing gastric acidity, while magnesium hydroxide not only helps to neutralize stomach acid but also can have a mild laxative effect. The combination of these two substances allows for effective symptom relief and can help neutralize both the acidity and the potential gastrointestinal side effects that may arise from using a single antacid. In contrast, the other answer options consist of medications that belong to different pharmacological categories. For instance, the first choice includes guaifenesin, an expectorant, and omeprazole, which is a proton pump inhibitor aimed at reducing gastric acid production. The third choice lists dextromethorphan, a cough suppressant, and codeine, an opioid that also has antitussive effects but does not neutralize stomach acid. Lastly, the fourth selection features famotidine and ranitidine, which are histamine H2-receptor antagonists, reducing gastric acid secretion rather
