Patients with heartburn are often diagnosed with GERD (gastroesophageal reflux disease) and treated with a drug called a proton pump inhibitor (PPI) to reduce stomach acid production. It is pretty effective, but it doesn’t always work. When it doesn’t, standard practice has been to double the dose of PPI. Doubling the dose only improves symptoms in 20-25%. Most patients who fail the single dose turn out to have normal esophageal acid exposure, or “functional” heartburn. In other words, the symptoms appear to be due to something other than excess acid – so it really may not make much sense to double the PPI dose. What else could doctors try?
