Histamine is a biological mediator used in physiological and pathological processes. Histamine plays an important role in inflammation, gastric acid secretion, immune responses, smooth muscle contractions and as a neurotransmitter. Endogenous histamine is synthesized in all tissues and is stored primarily in the granules of mast cells or basophils. Historically histamine is best known as a mediator of allergic reactions and inflammation, but it's function as a immunostimulant is being further investigated. Histamine dihydrochloride is a topical analgesic used for minor aches and pains of muscles and joints. It is also being researched as an orphan drug for the adjunctive treatment of acute myeloid leukemia or malignant melanoma.
