I have been seeing a lot of posts talking about how NSAIDS/antihistmains causing less flaring for people on this em forum and others. I think i found out why. I was looking over some studies on chronic inflammation and found that prostaglandin's/histamine are potent vasodialators. and guess what?? NSAIDS/antihistamins stop this reaction from taking place. to sum things up as simple as i can:
Prostaglandins/histamine cause vasodialation (bad for us with EM)
NSAIDS/Corticosteroids/COX-2 selective inhibitors: these cause prostaglandins not to do there job, thus stopping the vasodialation that they cause. (less flares for most of us)
Anti-histamine: Cause histamine not to do its job, reducing the vasodialation that they cause. (again, less flares for us as an effect)
Some helpful quotes:
Examples of prostaglandin antagonists are:
NSAIDs (inhibit cyclooxygenase)
Corticosteroids (inhibit phospholipase A2 production)
COX-2 selective inhibitors or coxibs
Cyclopentenone prostaglandins may play a role in inhibiting inflammation
[edit]Clinical uses of synthetic prostaglandins:
Synthetic prostaglandins are used:As a vasodilator in severe Raynaud's phenomenon or ischemia of a limb. (this is a key trait of synthetic prostaglandins. if you block there
effects, you help erythromelalgia)
Here is a quote on antihistamins:
Antihistamines suppress the histamine-induced wheal response (swelling) and flare response (vasodilation) by blocking the binding of histamine to its receptors on nerves, vascular smooth muscle, glandular cells, endothelium, and mast cells. They exert a competitive antagonism to histamines.

If you think I am wrong, let me know! It just seems very very straight forward and easy to understand. let me know what you guys think :D
