GASTROINTESTINAL AGENTS

The gastrointestinal agents are reduced to three major categories. First, anti-ulcer agents act by reducing the stomach acid content either by directly neutralizing H⁺ or reducing the amount of acid produced. Some anti-ulcer agents may act to coat existing ulcers to prevent further damage. Second, anti-emetics act on centers in the brain to reduce the incidence of vomiting. The final category serves to either speed up or slow down the intestinal system. This is accomplished by either increasing or decreasing the water content of the stool or by increasing/decreasing gastrointestinal motility.
