Abstract:
A 29-old man presented with severe chronic urticaria and angioedema. Routine evaluation including history, laboratory parameters and imaging procedures did not reveal any pathologic findings. We tried combined therapy regimes including high-dose systemic corticosteroids and antihistamines, leukotriene antagonist, cyclosporine and antibiotics. Because of a poor response and dramatic escalation of symptoms, we initiated therapy with omalizumab resulting in the complete remission of the chronic urticaria after two weeks.

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...

Antiasthma Drugs: Muscarinic Receptor Antagonists
Antimuscarinic agents compete with ACh for the same binding site on the muscarinic receptors. By binding to these receptors, they inhibit the downstream effects of ACh and block the parasympathetic...
