Table: USAN Stems for Gastrointestinal Agents

Gastrointestinal agents are used to treat conditions of the GI tract, including constipation, diarrhea, gastroesophageal reflux (GERD), heartburn, indigestion, nausea, spasms, ulcers, and vomiting. Ulcers can be caused by excess acid production, chronic use of nonsteroidal anti-inflammatory agents, or by the bacteria Helicobacter pylori. The most effective way to treat ulcers caused by H. pylori is to use drug combinations that include acid-reducing agents and antibiotics. Although most of these medications can be taken orally, intravenous, topical, and rectal formulations are available for patients who require alternative routes (Table). Common side effects of the gastrointestinal agents include upset stomach, nausea and vomiting, and headaches.
