Mucosal lesions in the g.i. tract due to ASA and other nonsteroidal anti-inflammatory drugs are well-known in clinical practice. Though the gastroduodenal mucosa is the area most commonly investigated, several recent reports focus on lesions in the small and large intestine as well. Despite considerable efforts in the field, none of the new substances developed in the past few years have proven convincingly superior to existing drugs. Instead, other approaches are being evaluated: Bypassing of the gastroduodenal mucosa through enteric coating and slow release formulations have been suggested, but the possibility of transferring the deleterious effects to distal parts of the gastrointestinal tract by such formulation modifications calls for extensive evaluation of this area, before these formulations can be applauded as advantageous in this group of patients. Co-administration of protective substances has also been advocated, and, despite somewhat contradictory results, protection has been reported by H2-antagonists alone or in combination with antacids, as well as by cytoprotective agents like Sucralfate, and prostaglandin analogues.

The proton pump inhibitors omeprazole and lansoprazole and the histamine H2 receptor antagonists ranitidine and nizatidine were investigated for their effects on gastric transmucosal potential difference (PD) in the rat, in comparison with the gastroprotective compound sucralfate. Omeprazole (1-3 mg kg-1, i.v.) and lansoprazole (1-3 mg kg-1, i.v.) did not modify basal PD, but significantly reduced (by approx. 50-60%) the drop in PD caused by intragastric administration of acetylsalicylic acid (ASA, 60 mg kg-1). Ranitidine (3-100 mg kg-1, i.v.) and nizatidine (10-30 mg kg-1, i.v.) behaved similarly to proton pump inhibitors, being ineffective on basal PD, while significantly reducing the effect of ASA. The antisecretory compounds did not change basal pH values. Sucralfate (0.5-1.5 g kg-1 intragastrically) caused a slight increase (approx. 20%) of basal PD and a dose-dependent reduction of ASA-induced fall in PD, with a maximum effect (65% reduction) comparable to that caused by the antisecretory agents. These results showed that ASA-induced disruption of the mucosal barrier can be reduced to the same extent by various antiulcer drugs, irrespective of their effects on gastric acid secretion.

The efficacy of antacids in the short- and long-term treatment of peptic ulcers, has suggested a possible use in the prevention and in the treatment of non-steroidal anti-inflammatory drug related gastroduodenal lesions. In short-term prevention studies, significant protection against ASA-related lesions was observed when antacids at high-dose were given before the administration of the offending drug. To the contrary, antacids at low dose did not prevent ASA-induced lesions of gastric and duodenal mucosa. As for long-term prophylaxis, no clinical effect was observed. In the treatment of non-steroidal anti-inflammatory drug-related mucosal lesions in patients who were able to discontinue the offending drugs, antacids proved of some use, when compared with placebo, but were significantly less effective than H2 blockers, as cimetidine. Sucralfate is an effective antiulcer drug thought to provide cytoprotective action. Although initial studies utilizing sucralfate for protection against short-term aspirin administration were encouraging, longer term studies (more than 7 days) were generally disappointing. A comparative study with misoprostol demonstrated that the PGE1 analogue was far superior for the prevention of non-steroidal anti-inflammatory drugs ulcers, and that ulceration rates in the sucralfate group were equivalent to rates in the placebo group. As far as the treatment of non-steroidal anti-inflammatory drug-related mucosal lesions is concerned, sucralfate proved superior to placebo, similar to ranitidine, but significantly less effective than omeprazole.

Allophylus serratus is known to possess various therapeutic properties. We evaluated the anti-ulcerogenic property of crude ethanolic extract of Allophylus serratus (AS) in different ulcer models in Sprague-Dawley rats. The extract at 400 mg/kg body weight, once daily, orally has a significant effect in cold restraint (CRU, 2 h cold restraint stress), aspirin (ASA, 150 mg/kg body weight, orally), alcohol (AL, 1 ml/200 gm of absolute alcohol) and pyloric ligation (PL, 4h ligation) induced gastric ulcer models as it showed protection index of 71.28, 62.50, 90.84 and 64.29% protection, respectively whereas, standard drug omeprazole (OMZ, 10mg/kg body weight) has shown protection index of 85.70, 74.99 and 74.99 in CRU, ASA and PL model respectively. Sucralfate (SUC, 500 mg/kg body weight) as a standard drug in AL model has 93.20% protection. Furthermore, AS has significantly decreased the free acidity (72.41%), total acidity (47.97%) and peptic activity (24.59%), respectively as well as has significantly increased the mucus secretion (29.41%). Conclusively the ulcer protective effect of AS may be due to its anti-secretory along with cytoprotective mechanism.
