Histamine (H2) blockers: Four histamine blockers are available in the United States. Some are available without a prescription (see above); others require a prescription.
Proton pump inhibitors (PPIs): These medications are very powerful blockers of the stomach's ability to secrete acid.
Coating agents: These medications protect the stomach's lining.
Antibiotics: An antibiotic may be prescribed if H pylori is demonstrated to be the cause of the patient's gastritis.
Antiemetics: Antiemetic medications help control nausea and vomiting. A number of different antiemetics can be used in the emergency department to control gastritis symptoms. Some of these medications are available by prescription for home use as well. Note that these medications do not improve the gastritis, but rather only decrease the symptoms of gastritis.
