Lansoprazole ineffective for functional dyspepsia.

Patients with functional dyspepsia, which involves no organic disease and no reflux, do not benefit from lansoprazole, a proton pump inhibitor. Any improvement seen is probably related to a placebo effect. Prescribing proton pump inhibitors for these patients just for their placebo effect is going to further raise health care costs. Antacids and H2 blockers are less expensive alternatives.
