E-drug: ADRs and cox 2 inhibitors (continued)  
---------------------------------------------  
Celecoxib (CELEBREX) is a sulfonamide derivative. Sulfonamides are  
well known to cause (allergic) thrombocytopenia and may present as  
SCHONLEIN HENOCH syndrome in children. Therefore, this should be  
considered in the case reported by Jody Dalmacion from the  
Philippines, especially if there were preceding expositions to  
sulfonamides.

Furthermore, all NSAIDs occasionally cause damage of the bone marrow  
including thrombocytopenia. However, the apparent acute onset argues  
against a toxic and for a immune allergic event.

Gastro-intestinal bleedings are not rare events with  
cox-2-inhibitors, since there is only a reduction of serious GI  
events (bleeding, perforation, ulcers) from 1.8 to 1.3 events per 100  
treatment years. You have to treat 200 patients for 1 year to prevent  
1 ulcer, at about 200.000 US$ treatment costs.

Healing such an event in the hospital only cost 2,000 US$. That is the  
price of innovations: 198.000 US$ more per ulcer treatment.
