There are various drugs that act on the gastrointestinal (GI) tract to treat different conditions. Here are some examples of such drugs:

Antacids: 

These drugs neutralize stomach acid and relieve symptoms of acid reflux, heartburn, and indigestion. Examples include 

• aluminum hydroxide, 
• magnesium hydroxide, and 
• calcium carbonate.

Proton Pump Inhibitors (PPIs): 

These drugs block the production of acid in the stomach and are used to treat gastroesophageal reflux disease (GERD) and peptic ulcers. Examples include omeprazole, lansoprazole, and pantoprazole.

H2 Receptor Antagonists: 

These drugs reduce the production of acid in the stomach and are used to treat acid reflux, GERD, and peptic ulcers. Examples include 

• ranitidine, 
• cimetidine, and 
• famotidine.

Prokinetics: 

These drugs increase the motility of the GI tract, improving digestion and reducing symptoms of conditions such as gastroparesis and constipation. Examples include 

• metoclopramide and 
• domperidone.

Antidiarrheals: 

These drugs slow down the movement of the GI tract, reducing diarrhea. Examples include
