Final answer:
Cimetidine, rantidine, famotidine, and nizatidine belong to the class of drugs called H₂ blockers, specifically H₂-receptor antagonists.
Step-by-step explanation:
Cimetidine, rantidine, famotidine, and nizatidine belong to the class of drugs called H₂ blockers, specifically H₂-receptor antagonists. These medications work by decreasing the amount of acid produced in the stomach, making them useful in the treatment of ulcers, gastroesophageal reflux disease (GERD), and conditions where the stomach produces too much acid. Examples of other H₂ blockers include ranitidine (Zantac) and famotidine (Pepcid AC).
The drugs cimetidine, ranitidine, famotidine, and nizatidine belong to a class known as H2 blockers. These medications work by reducing the amount of acid produced in the stomach. They are commonly used to treat conditions such as ulcers, gastroesophageal reflux disease (GERD), and Zollinger-Ellison syndrome. H2 blockers are different from antacids, which neutralize existing stomach acid, and from proton pump inhibitors like omeprazole, which also decrease stomach acid production but through a different mechanism.
