The first week on a proton pump inhibitor (PPI) "is only moderately useful for predicting responses after 4 and 8 weeks of treatment," Sander Veldhuyzen van Zanten, M.D., said at the 13th United European Gastroenterology Week. "It therefore makes sense to treat for 4-8 weeks" to see if the patient will eventually respond, said Dr. van Zanten, professor of medicine at Dalhousie University in Halifax, N.S.
The results also showed that a double dose of a PPI was no more effective than the standard dose when starting treatment.
"The data clearly show that in a primary care setting, unless a patient has alarming symptoms, there's no reason to start with a double dose of a PPI," Dr. van Zanten said.
