Azathioprine is an immunosuppressant medication that reduces overactive immune responses. It is commonly used as a long-term “maintenance” therapy in immune-mediated diseases. In gastroenterology, it is most often discussed in inflammatory bowel disease and autoimmune liver conditions. It is taken by mouth and typically works gradually rather than immediately.

Mesalamine is an anti-inflammatory medication used in inflammatory bowel disease (IBD). It is also called 5-aminosalicylic acid (5-ASA). It is most commonly used to treat ulcerative colitis, especially mild to moderate disease. It comes in oral and rectal formulations designed to deliver medication to the intestinal lining.

Rifaximin is a rifamycin-derived antibiotic that acts primarily inside the gastrointestinal (GI) tract. It is minimally absorbed into the bloodstream, so most of its activity is “luminal” (within the gut lumen). Clinicians most often use it in hepatology and gastroenterology for specific bowel- and liver-related conditions. It is prescribed as an oral medication rather than given by injection.

Antispasmodics are medications used to reduce involuntary muscle spasms. In gastroenterology, they are most often used to ease cramping pain from the gastrointestinal (GI) tract. They are commonly discussed in functional bowel disorders and in some endoscopy settings.

Antiemetics are medicines used to prevent or treat nausea and vomiting. They are commonly used in gastroenterology, surgery, oncology, and emergency care. They work by targeting specific receptors and pathways involved in the vomiting reflex. They are chosen based on the likely cause of symptoms and patient factors.

Prokinetics are medications that increase or coordinate movement (motility) in parts of the gastrointestinal (GI) tract. They are used when food, liquid, or gas moves too slowly or in an uncoordinated way. They are commonly discussed in disorders of the esophagus, stomach, and intestines. In clinical practice, they are part of symptom-based care for nausea, reflux-related symptoms, and constipation in selected cases.

Stool Softeners are medications used to make stool easier to pass. They are commonly discussed in the setting of constipation and straining. In clinical practice they are often used in hospitals and after surgery. They are also used in outpatient care when hard stools worsen anorectal symptoms.

Laxatives are medications or substances that help promote bowel movements. They are commonly used to manage constipation and to support bowel emptying. They are also used in gastroenterology for colonoscopy preparation and selected liver-related indications.

An Antacid is a medication that neutralizes stomach acid in the upper gastrointestinal (GI) tract. It is commonly used for short-term relief of heartburn, acid indigestion, and dyspepsia (upper abdominal discomfort). Many Antacid products are available over the counter, and some are used in inpatient settings as supportive therapy.

An H2 Blocker is a medication class that reduces stomach acid production. It works by blocking histamine type-2 (H2) receptors on acid-producing cells in the stomach. H2 Blocker drugs are commonly used for acid-related symptoms such as heartburn and dyspepsia. They are also used in hospitals for selected ulcer-prevention and bleeding-related situations.
