Nonsteroidal anti-inflammatory drugs and immunologic function. Overview of the European experience
Abstract:
A large number of nonsteroidal anti-inflammatory drugs are available in Europe. There appears to be little difference in overall clinical effectiveness of these drugs, despite individual patient variation, suggesting a common mode of action. Occasionally, a nonsteroidal anti-inflammatory drug will show some evidence of a more impressive anti-rheumatic effect, perhaps related to a more prolonged or different mode of action. The evidence for an immunologic effect of nonsteroidal anti-inflammatory drugs is largely derived from in vitro studies. In patients with rheumatoid arthritis treated with piroxicam, there are no overall changes in lymphocyte numbers or T4/T8 ratios, but numbers of activated cells expressing la decrease and rheumatoid factor titers may also fall. It is suggested that this is not a direct immunosuppressive effect, but one that is related to local inhibition of polymorphonuclear leukocyte-derived free radical production within the joint, which may lower the antigenic load of IgG altered by free radicals, with subsequent diminished immune stimulation.

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...
