Management of NSAID-induced Gastrointestinal Lesions

Abstract

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.
