Most allergic reactions include a common pathway of release of histamine from the mast cells. Histamine binds to the histamine receptors in other cells causing itching, swelling and redness typical of these allergies.
Therefore, a very important group of drugs to treat allergy are the histamine receptor blockers, which prevent the cells to be activated by histamine and therefore decrease the allergic reaction.
Belonging to this group of drugs are, among others:
- Loratadine
- Lorastine
- Allergyx
- Zyllergy
- Aerius
- Telfast
- And much more.
