What class of medication is often used to treat dyspepsia by inhibiting gastric acid?

H2 receptor antagonists are a class of medications commonly used to treat dyspepsia by selectively inhibiting gastric acid secretion. They work by blocking histamine H2 receptors located on the parietal cells of the stomach, which leads to a decrease in the production of gastric acid. This reduction in acid secretion can help alleviate symptoms of dyspepsia, such as heartburn, stomach pain, and indigestion, making H2 receptor antagonists an effective treatment option for managing these conditions.

Antibiotics are primarily used to treat bacterial infections and would not directly address the symptoms of dyspepsia related to gastric acid secretion. SSRIs are a class of medications typically used to treat depression and anxiety disorders and do not play a role in the management of gastric acid-related conditions. Opioids are pain-relieving medications that can actually slow gastrointestinal motility and potentially worsen dyspeptic symptoms rather than provide relief. Thus, H2 receptor antagonists are the most appropriate choice for treating dyspepsia through the inhibition of gastric acid secretion.
