Abstract

The use of nonsteroidal anti-inflammatory drugs (NSAIDs) is limited by their ability to induce gastrointestinal injury. It has been shown that nitric oxide (NO), similar to pro staglandins (PGs), appears to play an important role in gastric mucosal defence. We hypothesized that NSAIDs contained NO group would be less acutely toxic to the gastric mucosa, but would not interfere with their ability to suppress inflammatory process in rats. We have compared the ulcerogenic and anti-inflammatory effect of CW-501029 (NO-NSAIDs), CW-501027 (NSAIDs) and indomethacin. Both did not change mean blood pressure and heart rates, indicating that they had no side effect on cardiovascular system. We found that CW-501029 increased nitrite/nitrate levels without changing of blood pressure and heart rates. We suggest that it may help gastric mucosal blood flow, the which helps reducing the discomfort in astrointestinal system. Carrageenan-induced PGE2 increase was reduced in a similar tendency when compared CW-501027 or CW-501027 with control in back exudate of rats, but CW-501029 less reduced PGE2 than CW-502027 or indomethacin in gastric tissues. CW-501027 or CW-501029 reduced platelet aggregation. From these results we suggest that CW-501029 may improve the side effect by reduction of short-term gastric injury and less inhibition of PGs synthesis.
