Final answer:
Examples of H2 blockers are Ranitidine (Zantac), Famotidine (Pepcid AC), and Cimetidine (Tagamet), which are used to decrease stomach acid production and treat ulcers, GERD, and Zollinger-Ellison syndrome.
Step-by-step explanation:
Medication examples of H2 blockers include Ranitidine (Zantac), Famotidine (Pepcid AC), and Cimetidine (Tagamet). These medications are part of a class of drugs that decrease the amount of acid made in the stomach. They are commonly used to treat conditions such as ulcers, gastroesophageal reflux disease (GERD), and Zollinger-Ellison syndrome. Unlike antacids which neutralize acid, H2 blockers work by blocking histamine Hâ‚‚ receptors in the stomach to reduce acid production.
Conditions like peptic ulcers and acid reflux often require a treatment that extends beyond antacids. In cases where ulcers are caused by NSAIDs, patients may need to switch pain relievers, and H. pylori infections often necessitate antibiotic therapy. H2 blockers play a role in these treatment plans by decreasing gastric acid and aiding symptom relief and healing.
