How This Drug Works
Antihistamines, H1
Histamine antagonists or antihistamines are drugs that relieve allergy symptoms. Histamine is a chemical used to identify and remove substances that trigger an allergic response.
Histamine antagonists or antihistamines are drugs that relieve allergy symptoms.<br><br>Histamine is a chemical used to identify and remove substances that trigger an allergic response.  There are four histamine receptors &#40;designated H<sub>1</sub>, H<sub>2</sub>, H<sub>3</sub>, H<sub>4</sub>&#41;. When histamine activates H<sub>1</sub> receptors, symptoms such as rashes, itching, watery eyes and trouble breathing may begin. <br><br>Antihistamines prevent histamine from stimulating the H<sub>1</sub> receptors located in the eyes, nose and throat to relieve swelling and stop leaking fluid.  First generation antihistamines were non-selective for H<sub>1</sub> receptors and crossed into the brain resulting in drowsiness.  Newer antihistamines are more selective, reducing this side effect.
