Abstract:
With the help of a routine clinical case about delayed urticaria induced by drug, we have analyzed the scientific societies reports published during the last 5 years on this topic. We highlighted the differences between the EAACI consensus and documents on drug allergy, commenting their positions and some of their definitions on delayed urticaria. However, the question of disagreement between definitions of delayed urticaria can generate confusion. It would be beneficial to have more and "official" clearness about this topic because of its important clinical application to our patients.

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...
