The suffix '-tidine' is commonly associated with which class of medications?

Explanation:
The suffix -tidine identifies a class of medications known as H2 receptor antagonists. These drugs work by blocking histamine at the H2 receptors on gastric parietal cells, which reduces gastric acid secretion and raises the stomach’s pH. They’re commonly used to treat conditions like GERD, peptic ulcers, and gastritis. Examples include cimetidine, ranitidine, famotidine, and nizatidine. This suffix helps distinguish them from other classes that have different suffixes, such as beta blockers (-olol), ACE inhibitors (-pril), and proton pump inhibitors (-prazole), which use different mechanisms for controlling acid or cardiovascular effects.
