In medicine and pharmacology, anti-ulcer agents are "various agents with different action mechanisms used to treat or ameliorate peptic ulcer or irritation of the gastrointestinal tract. This has included antibiotics to treat helicobacter infections; histamine h2 antagonists to reduce gastric acid secretion; and antacids for symptomatic relief."[1] Proton pump inhibitors also are used.

Symptomatic relief should not preclude definitive treatment.

Drug toxicity

These medications may be associated with pneumonia.[2]
