Increased excretion of histamine in urine

Introduction Histamine is a reactive amine compound with the chemical formula C5H9N3 and a molecular weight of 111. As a chemical conductive substance in the body, it can affect the reaction of many cells, including allergies, inflammatory reactions, gastric acid secretion, etc. It can also affect the nerve conduction in the brain, which can cause sleep and other effects. The metabolites after taking H1 receptor antagonists (ie, antihistamines) are excreted in the kidneys for a few to several tens of hours, and the urine excretion accounts for a large part. This leads to an increase in histamine excretion in the urine.

Cause

H1 receptor antagonist (ie, antihistamine) Histamine is a reactive amine compound due to histamine-mediated dermatosis. As a chemical conductive substance in the body, it can affect the reaction of many cells, including allergies, inflammatory reactions, gastric acid secretion, etc. It can also affect the nerve conduction in the brain, which will cause the body to sleep.

Indications: Suitable for alleviating the symptoms of the following diseases. Allergic rhinitis, including hay fever, histamine-mediated skin disorders, including related allergic skin disorders. For example: chronic urticaria, skin scratches, biliary urticaria, idiopathic acquired cold urticaria, atopic dermatitis.

Differential diagnosis

Histamine phosphate, which is administered orally, is quickly inactivated in the stomach. Subcutaneous, intramuscular or intravenous administration produces rapid and transient effects. This product is methylated and oxidized, and its metabolites are excreted in the urine.
