H 1 -antihistamines work by binding to histamine H 1 receptors in mast cells, smooth muscle, and endothelium in the body as well as in the tuberomammillary nucleus in the brain. Antihistamines that target the histamine H 1 -receptor are used to treat allergic reactions in the nose (e.g., itching, runny nose, and sneezing). In addition, they may be used to treat insomnia, motion sickness, or vertigo caused by problems with the inner ear. H 2 -antihistamines bind to histamine H 2 receptors in the upper gastrointestinal tract, primarily in the stomach. Antihistamines that target the histamine H 2 -receptor are used to treat gastric acid conditions (e.g., peptic ulcers and acid reflux ).

What antihistamines are used for opioids?

The first generation of antihistamine drugs became available in the 1930s. This marked the beginning of medical treatment of nasal allergies. Research into these drugs led to the discovery that they were H1 antagonists and also to the development of H2 antagonists, where H1 antihistamines affected the nose and the H2 antihistamines affected the stomach. This history has led to contemporary research into drugs which are H3 receptor antagonist and which affect the Histamine H4 receptor. Currently most people who use an H 1 receptor antagonist to treat allergies use a second- or third-generation drug.

An H3-antihistamine is a classification of drugs used to inhibit the action of histamine at the H 3 receptor. H 3 receptors are primarily found in the brain and are inhibitory autoreceptors located on histaminergic nerve terminals, which modulate the release of histamine. Histamine release in the brain triggers secondary release of excitatory neurotransmitters such as glutamate and acetylcholine via stimulation of H 1 receptors in the cerebral cortex. Consequently, unlike the H 1 -antihistamines which are sedating, H 3 -antihistamines have stimulant and cognition-modulating effects.
