Fast and Specific Assessment of the Halogenating Peroxidase Activity in Leukocyte-enriched Blood Samples
Published on: July 28, 2016
Abstract:
Lodoxamide tromethamine and several other anti-allergy drugs, i.e. inhibitors of rat passive cutaneous anaphylaxis, are inhibitors of purified xanthine oxidase. Inhibition is noncompetitive with Ki's in the 1-13 micromolar range. Lodoxamide tromethamine had no effect on another flavoprotein, glucose oxidase. Other studies have shown several of these drugs are inhibitors of aldose reductase. It is speculated that the anti-allergy drugs inhibit mediator release from mast cells by blocking univalent electron transfers which are essential for release.

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...
