Question

Provide examples of Histamines and Antihistamines which are most common.

Answer 1

I think the concept of histamines is a bit unclear to you . Histamine is a compound which is released by cells in response to injury and in allergic and inflammatory reactions, causing contraction of smooth muscle and dilation of capillaries.

Some common antihistamines include:

• Allegra (fexofenadine)
• Astelin and Astepro (azelastine) nasal sprays.
• Atarax and Vistaril (hydroxyzine)
• Benadryl (diphenhydramine)
• Chlor-Trimeton (chlorpheniramine)
• Clarinex (desloratadine)
• Claritin and Alavert (loratadine)
• Cyproheptadine.
