    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.)

    5.2 FDA Pharmacological Classification
    5.2.1 Pharmacological Classes
    Proton Pump Inhibitor [EPC]; Proton Pump Inhibitors [MoA]; Cytochrome P450 2C19 Inhibitors [MoA]
