The document discusses several classes of medications that affect digestion and nutrition, including their mechanisms of action, therapeutic uses, side effects, and interactions. Histamine-2 receptor antagonists like ranitidine are used to treat ulcers and GERD by blocking acid secretion. Proton pump inhibitors like omeprazole provide a stronger inhibition of acid production. Sucralfate protects ulcers with a viscous gel. Antacids neutralize acid. Prostaglandin analogs increase mucus and blood flow in the stomach.
