Prevention of non-steroidal anti-inflammatory agents induced acute gastric mucosal lesions by carbonic anhydrase inhibitors. An endoscopic study



Prevention of non-steroidal anti-inflammatory agents induced acute gastric mucosal lesions by carbonic anhydrase inhibitors. An endoscopic study



Acta Physiologica Hungarica 73(2-3): 279-283



The present paper studies the effect of acetazolamide, an inhibitor of carbonic anhydrase, on acute gastric mucosal damage induced by non-steroidal anti-inflammatory drugs. The study was performed on healthy male subjects. The drugs tested were aspirin (1.5 g/day), indomethacin (75 mg/day), phenylbutazone (600 mg/day) and ibuprofen (600 mg/day) given for 7 days in 3 divided doses. Each drug was given to 5 cases in two separate periods, during which they were given acetazolamide 20 mg/kg/day or placebo in random order. Dyspeptic symptoms were evaluated. Endoscopy was performed before, and 3 and 7 days after NOSAC administration. Gastric mucosal lesions were evaluated according to the scale proposed by Lanza (J. Clin. Pharmacol., 24: 1984, 89) and the severity of the lesions was calculated. All drugs tested produced dyspeptic symptoms and acute mucosal damage of the gastric mucosa. Inhibition of gastric mucosa carbonic anhydrase by acetazolamide cessated promptly dyspeptic symptoms and reduced significantly the number and severity of drug-associated mucosal lesions.
