Drugs for Treatment of Ulcerative Colitis in IBD
129
Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide...

Acid Suppressive Drugs for Peptic Ulcer Disease: Proton Pump Inhibitors
361
Peptic ulcers, often induced by H. pylori infections or NSAID usage, arise from disruptions in the delicate balance of gastric acid production. Peptic ulcers stem from heightened gastric acid levels due to H. pylori infections or NSAID use. The protective mucus layer diminishes in the presence of these factors, allowing gastric acid to erode the stomach lining and form ulcers.

Drugs for Treatment of Constipation-Predominant IBS
143
Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...

Drugs for Peptic Ulcer Disease: Prostaglandin Analogs as Mucosal Protective Agents
375
The gastric mucosa produces prostaglandins E2 (PGE2) and prostacyclin (PGI2), crucial in maintaining gastric health. They exert cytoprotective effects, including increasing bicarbonate secretion, releasing protective mucin, reducing gastric acid output, and preventing harmful vasoconstriction. These effects are mediated through various receptors, such as EP1, EP2, EP3, and EP4.
