Protective effect of rioprostil on indomethacin-induced lesions of gastric and duodenal mucosa in healthy volunteers.
The protective effect of rioprostil against gastroduodenal mucosal lesions induced by indomethacin is investigated in a double-blind controlled trial on 36 healthy adult volunteers, divided into three groups. All the volunteers are treated with indomethacin, 50 mg t.d.s. during a period of 5 days. The first group is treated with placebo, the second with rioprostil, 300 micrograms, and the third with rioprostil, 600 micrograms. Endoscopies are performed before and after treatment. Blood samples for high performance liquid chromatography determination of indomethacin plasma concentrations are taken on the 6th day, before the last dose of indomethacin is administered, and 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12 and 24 h after the last dose of indomethacin. It is found that in both doses rioprostil exerts a protective effect against indomethacin-induced lesions, reducing the appearance rate of erosions from 67% to 17% statistically significant in the 600 micrograms group. The bioavailability of indomethacin in the three groups does not differ significantly.

Endoscopic evaluation of rioprostil in the management of non-steroidal anti-inflammatory drug-induced gastritis: an interim analysis.
The effects of the synthetic prostaglandin E1 analogue, rioprostil, on non-steroidal anti-inflammatory drug-induced (NSAID) gastritis are investigated. The study is of randomized, double-blind design. Patients are included who had classical or definite rheumatoid arthritis or osteoarthritis, had been taking a stable dose of NSAID or aspirin for at least one month and had endoscopically proven gastric lesion. Endoscopy is performed prior to, and at 4, 8 and 12 weeks of the treatment period. Patients receive either rioprostil, 300 micrograms or 100 micrograms q.d.s., or placebo q.d.s. The results of the endoscopies show greater healing of the mucosa in patients taking rioprostil compared with those taking placebo. It is therefore concluded that rioprostil is an effective compound for the management of patients with NSAID-induced gastritis.

Prophylactic and therapeutic role of rioprostil in NSAIDs induced gastroduodenal lesions.
In a randomized, double-blind, placebo-controlled, prospective trial, the activity of rioprostil, a new prostaglandin E1 alcohol analogue, on non-steroidal anti-inflammatory drug-induced gastroduodenal mucosal lesions is studied in 30 patients with rheumatic diseases. Both treatment regimens, rioprostil, 150 micrograms t.i.d., and rioprostil, 200 micrograms b.i.d., for a period of 12 weeks, significantly reduce the rate of mucosal lesions in all patients when compared to placebo. Furthermore, rioprostil achieves a reduction in gastrointestinal symptoms without enhancement of joint disease activity, and significantly reduces antacid intake. Therapy is safe and well tolerated by all patients. It can be concluded from this study that prostaglandins could play an important part in the prevention and treatment of gastrointestinal damage due to NSAIDs.
