1. Antihistamines (under construction)

   The antihistamines recommended for or prescribed to treat allergic reactions, occasional insomnia, motion sickness or vertigo, and nausea and vomiting target histamine H₁ receptors on mast cells, smooth muscle, endothelium, and in the brain’s tuberomammillary nucleus (a structure of histamine-releasing neurons in the posterior third of the hypothalamus involved in regulating arousal, learning, memory, sleep and energy balance). Antihistamine drugs act mechanistically as receptor antagonists or inverse agonists.
