What are antihistamine? Give two examples. |
|
Answer» Antihistamines are drugs which either reduce or inhabit the action of histamine in the body thereby preventing allergy. Two important antihistamines are brompheniramine and terfenadine. Mode of action: Histamines interact with the binding sites of receptor in the body to produce allergy. Antihistamines compete with histamines for these binding sites of receptor and thus do not allow histamine to produce allergy. |
