5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Anti-Ulcer Agents

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. (See all compounds classified as Anti-Ulcer Agents.)


Proton Pump Inhibitors

Compounds that inhibit H(+)-K(+)-EXCHANGING ATPASE. They are used as ANTI-ULCER AGENTS and sometimes in place of HISTAMINE H2 ANTAGONISTS for GASTROESOPHAGEAL REFLUX. (See all compounds classified as Proton Pump Inhibitors.)
