A drug may be classified by the chemical type of the active ingredient or by the way it is used to treat a particular condition. Each drug can be classified into one or more drug classes. Antihistamines are drugs that inhibit the action of histamine in the body by blocking the receptors of histamine. There are two types of histamine receptors H1 and H2. When H1 receptors are stimulated by histamine it may produce allergic reactions such as itching, hay fever and rash or hives.
Histamine is the primary effector substance released by the mast cell in response to an allergen. Antihistamines block H1 (histamine, type 1) receptors found on blood vessel endothelial cells and smooth muscle cells.he use of antihistamines to treat hayfever will also help to relieve asthma and reduce the severity of its symptoms. Antihistamines are available in tablet, nasal spray, cream, and eye drop form. The eye drops are useful for the red and itchy eyes often caused by airborne allergens like pollen.
