    5 Pharmacology and Biochemistry
    5.1 MeSH Pharmacological Classification

    Cytochrome P-450 CYP1A2 Inhibitors

    Drugs and compounds which inhibit or antagonize the biosynthesis or actions of CYTOCHROME P-450 CYP1A2. (See all compounds classified as Cytochrome P-450 CYP1A2 Inhibitors.)

    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.)

    Histamine H2 Antagonists

    Drugs that selectively bind to but do not activate histamine H2 receptors, thereby blocking the actions of histamine. Their clinically most important action is the inhibition of acid secretion in the treatment of gastrointestinal ulcers. Smooth muscle may also be affected. Some drugs in this class have strong effects in the central nervous system, but these actions are not well understood. (See all compounds classified as Histamine H2 Antagonists.)
