Gastrointestinal agents are medications used to treat various digestive system disorders. They can help alleviate symptoms such as heartburn, nausea, constipation, and diarrhea. Common types include antacids, which neutralize stomach acid, and laxatives, which promote bowel movements. These agents work by targeting specific issues within the gastrointestinal tract. For example, proton pump inhibitors reduce acid production in the stomach, while antidiarrheals slow down bowel movements to manage diarrhea. Overall, gastrointestinal agents play a crucial role in maintaining digestive health and improving quality of life for those with gastrointestinal conditions.
