Ethanol, aspirin, ibuprofen, and the gastroduodenal mucosa: an endoscopic assessment.

The effect on the gastroduodenal mucosa of alcohol combined either with aspirin or ibuprofen was studied in 60 normal volunteers. The volunteers were divided into six groups comprised of 10 subjects receiving ibuprofen, placebo, or aspirin with or without alcohol. Medications consisted of 1) three 325-mg aspirin tablets, or three identical placebo tablets, 2) one 600-mg ibuprofen tablet, and 3), three ounces of 100 proof vodka diluted in 6 ounces of orange juice, or alcohol placebo made by diluting 3 ounces of water in orange juice. All subjects received 4 doses over a 24-hr period and underwent endoscopic examination the following morning. The gastroduodenal mucosa was graded according to a 0 to 4 + scale. Aspirin caused considerably greater duodenal and gastric damage than did either ibuprofen or placebo. The addition of alcohol to all drugs increased the damage seen in the stomach but not to a significant degree; this effect was slightly more pronounced with ibuprofen than with placebo or aspirin and approached significance (0.1 greater than p greater than 0.05). These results are compatible with alcohol being a mild damaging agent or a potentiating agent for damage from other drugs.
