The 37 pages that link to Histamine, each with the reason it gives.

• AnaphylaxisRelated: Histamine contributes to swelling, hives, and airway symptoms after mediator release.

• NorepinephrineCompared with: Both influence alertness, but histamine uses distinct receptors and neural pathways.

• Allergic rhinitisRelated: Histamine drives much of the itching, sneezing, and watery discharge.

• Food allergyRelated: Its release contributes to hives, swelling, itching, and airway symptoms.

• AllergyRelated: Histamine contributes to itching, swelling, sneezing, and hives during allergic reactions.

• Histamine H1 receptorRelated: Histamine is the endogenous ligand that activates the H1 receptor.

• Mast cellBroader topic: Mast-cell histamine drives itching, swelling, and many immediate allergy symptoms.

• AntihistamineRelated: Antihistamines reduce effects produced when histamine activates its receptors.

• CatecholamineCompared with: Like catecholamines, it is a signaling amine, but its structure and precursor differ.

• PruritusRelated: Histamine released in skin can activate itch-sensing nerve endings.

• UrticariaRelated: Histamine produces much of the itching and fluid leakage in wheals.

• AngioedemaRelated: Histamine-mediated swelling often occurs with hives and may respond to antihistamines.

• AllergenRelated: Histamine is one mediator released after allergen recognition.

• Immunoglobulin ERelated: Its release after IgE-driven degranulation contributes to itching, swelling, and bronchoconstriction.

• BradykininCompared with: Like bradykinin, histamine can increase vascular permeability, but it uses different receptors and pathways.

• Latex allergyRelated: Histamine helps produce the rapid symptoms of IgE-mediated latex reactions.

• CetirizineNarrower topic: Cetirizine counteracts histamine’s effects that produce itching, swelling, and other allergy symptoms.

• FamotidineRelated: Histamine activates the receptor that famotidine blocks.

• ConjunctivitisRelated: Allergen-triggered histamine release helps explain itching in allergic conjunctivitis.

• Histamine fish poisoningBroader topic: This heat-stable compound accumulates in fish and drives the illness.

• Anaphylactic shockRelated: Its rapid release contributes to the pressure drop and fluid shift in shock.

• Cat allergyRelated: Its release contributes to itching, sneezing, and nasal swelling.

• ModafinilRelated: Modafinil may recruit histamine pathways that support sustained alertness.

• TyramineCompared with: Histamine is another food-associated biogenic amine, but it acts through different receptors and pathways.

• HistidineBroader topic: Histidine is the amino acid precursor from which histamine is produced.

• James BlackRelated: Black’s work on histamine signaling led to the H2-blocking ulcer drug.

• PromethazineNarrower topic: Promethazine counters some effects of histamine by blocking H1 receptors.

• LoratadineRelated: Histamine release drives many symptoms loratadine is used to relieve.

• TryptamineCompared with: Like tryptamine, histamine is an amino-acid-derived signaling amine, but it has an imidazole ring.

• DesloratadineNarrower topic: Allergic symptoms treated by desloratadine arise partly from histamine signaling.

• MastocytosisRelated: Mast-cell mediator release can cause itching, flushing, and gastrointestinal symptoms.

• CadaverineRelated: It is another food-associated amine monitored alongside cadaverine.

• Daniel BovetRelated: Blocking histamine’s actions was central to Bovet’s work on antiallergic drugs.

• HivesRelated: Histamine widens small blood vessels and increases their permeability, producing itchy welts.

• Runny noseRelated: In allergic reactions, histamine promotes nasal symptoms, including watery secretion.

• SneezeRelated: Histamine release during allergic reactions can increase nasal irritation and sneezing.

• Urtica dioicaRelated: Histamine in nettle hairs contributes to the skin's response after contact.
