Low-dose aspirin is widely employed as antiplatelet therapy for cardio
vascular disorders. However, even in the dosages usually employed for
that purpose (75 to 325 mg daily), the drug maintains its ability to d
amage the gastric mucosa by inducing bleeding ulcers and/or erosions.
Pharmacological protection is therefore necessary. Specific long term
studies with histamine H-2 receptor antagonists or sucralfate are lack
ing, but data from trials on the prevention of gastric damage by other
nonsteroidal anti-inflammatory drugs (NSAIDs) are discouraging. Recen
t preliminary data suggest that misoprostol, in keeping with its abili
ty to protect both gastric and duodenal mucosa from long term NSAID tr
eatment, seems to be effective also against long term low-dose aspirin
therapy in this setting.
