H2 blockers end in

Explanation:
H2 blockers are histamine H2 receptor antagonists that reduce stomach acid, and they share a naming pattern: the ending -tidine signals this drug class. Examples include ranitidine, famotidine, cimetidine, and nizatidine. The other endings don’t consistently indicate this class: -line isn’t a marker for H2 blockers, -dine is too broad and appears in other drug groups, and -zine points to different classes of medications. So the ending that best identifies H2 blockers is -tidine.
