Observations on the gastric mucosa of rheumatic patients before and after ibuprofen administration as studied by the pentagastrin test, endoscopy, and light and electron microscopy.

The initial results of a study set up to investigate the gastric mucosa in rheumatic patients receiving ibuprofen are described. The study involved seven male patients, aged between 17 to 70 years, suffering from various rheumatic diseases. All patients received a daily dose of 1200 mg of ibuprofen per os divided into three fractions and taken over periods of treatment ranging from one to six weeks. On the data obtained by the gastric secretion test, endoscopy, and specific histological and ultrastructure studies it is concluded that, in the cases investigated, ibuprofen could not be shown to be responsible for any significant modification of the gastric mucosa.
