Abstract:
Eosinophils are believed to be one of the important sources of cytokines at the site of allergic inflammation. A novel antiallergic agent epinastine showed a dose- and time-dependent suppressive effect on IL-8, one of the chemokines for eosinophils, released from eosinophils isolated from atopic diseases. The time-dependent accumulation of IL-8 inhibited by cycloheximide and the evaluation of the IL-8 mRNA levels by reverse transcriptase-polymerase chain reaction suggested that its action occurred in the posttranscriptional processes. It was suggested that epinastine might prevent the autocrine cycle for recruitment of human eosinophils by inhibiting IL-8 release from these cells.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
