Arbaprostil (15(R)-15-methylprostaglandin E2) is a prodrug, which is activated by epimerization to form the active S-epimer. It was shown, that arbaprostil markedly accelerated the healing rate of active duodenal ulcers, due to inhibition of acid secretion as well as gastric cytoprotection.

Sample Use Guides
A multicenter study was conducted on 173 patients with active, endoscopically proven duodenal ulcers (158 men, 15 women). They were randomly assigned, in a double-blind manner, to two groups: those receiving placebo capsules (91 patients) and those receiving capsules containing 100 microgram of 15(R)-15-methyl prostaglandin E2 (arbaprostil) (82 patients). Each drug was ingested four times a day (1 h before meals and at bedtime) for 28 days.
