The side-effects of NSAIDs (Non-Steroidal Anti-Inflammatory Drugs) are            not appreciated by the average consumer. A review by Wolfe et.            al. (1999) helps put the problem in            perspective for one of the problems, i.e. gastrointestinal toxicity.            On the basis of conservative figures "...the annual number of            hospitalizations in the United States for serious gastrointestinal            complications is estimated to be at least 103,000. 
 
At an estimated            cost of $15,000 to $20,000 per hospitalization, the annual direct            costs of such complications exceed $2 billion." The emphasis of            cost fails to recognize the more important mortality rate for patients            hospitalized for NSAID-induced upper gastrointestinal bleeding which            is reported by Wolfe et. al. as            about 5 to 10 percent. 
They further report, "It has been            estimated conservatively that 16,500 NSAID-related deaths occur among             patients with rheumatoid arthritis or osteoarthritis every year in the            United States. This figure is similar to the number of deaths from the            acquired immunodeficiency syndrome [AIDS] and considerable greater than the            number of deaths from multiple myeloma, asthma, cervical cancer, or            Hodgkin's disease." 
 
 
 
NSAIDs cause problems in the entire gastrointestinal tract, 
(Roth, 1988)  ranging from peptic ulcers
(Gabriel et al., 1991; Griffin et al., 1991; Langman et al, 1994) to small  intestine 
(Melo Gomes et al., 1993) and colon problems. In a study to  determine the safety of low-dose daily aspirin therapy in the gastrointestinal  tract, it was concluded that the safety of even 10 mg of daily aspirin is  questionable
,(Cryer & Feldman, 1999) which is way below the typical  baby aspirin dosage of 80 mg. The problems do not stop in the gut; the breakdown  of the gut mucous membranes leads to leaky gut syndrome with all of its  ramifications, including liver toxicity.
One of the most common reasons for taking NSAIDs is to relieve joint pain.  Unfortunately the very thing that is expected to gain relief often makes the  condition worse by blocking glycosaminoglycans (GAGS) production necessary for  repair, 
(Dekel et al., 1980; de Vries et al., 1985; Hugenberg et al., 1993) in one in vitro study by as much  as 60-70%. 
(Yoo et al., 1992) Therapeutic levels of aspirin in  vitro have effects of suppressing proteoglycan biosynthesis in normal and  degenerating articular cartilage similar to several other NSAIDs 
(Brandt & Palmoski, 1984)  and  permeate osteoarthritic cartilage 35% more than in normal cartilage. 
(Palmoski et al., 1984)  Glucosamine is in the popular press as an aid to improve the symptoms of  osteoarthritis or joint pain. It is one of the glycosamionglycans.and the more  NSAIDs are taken to control joint pain the more the very thing that repairs the  joints is destroyed. It is a vicious circle.
