摘要: Aspirin often causes acute gastric mucosal damage that can be seen endoscopically or assessed indirectly (for example, by measuring increased gastrointestinal blood loss). The occurrence of most adverse effects is apparently related to the dose administered. This dose-response effect, evident in both endoscopic and microbleeding studies done after short-term aspirin administration, also associated with risk developing chronic ulcer. adaptation, lessening injury continued treatment, obscures interpretation results from administration. Moreover, evidence has frequently been ignored when lists complications side are compiled. absence symptoms does not correlate appears have no predictive value. Endoscopic linking extent degree various nonsteroidal anti-inflammatory drugs little value predicting frequency severity ulcer bleeding.
