[Application of proton pump inhibitor to special conditions; Zollinger-Ellison syndrome].
Before the mid-1970s, the most reliable therapy for Zollinger-Ellison syndrome (Z-E syndrome) was total gastrectomy since complete excision of gastrinoma is difficult in many cases due to multifocus and/or metastases. With the advent of H2-blockers gastric acid secretion can be controlled at safe levels (less than 10 mEq/h), and patients with Zollinger-Ellison syndrome can be managed medically. The problem of therapy with H2-blockers however, is that large doses are usually required and that a marked tachyphylaxis is frequently noted during long-term treatment. Treatment with new antisecretory drug, proton pump inhibitor, has been shown to be highly effective with relatively high doses and without tachyphylaxis, although long-term experience is still limited.
