I know that many of our refluxers have problems with breakthrough acid at night. I just read such an interesting study about breakthrough acid. To summarize, the authors say found that timing of the period of breakthrough acid was related to the timing of the last meds. For patients who took their PPIs once in the morning, the breakthrough acid period was around 10pm, for patients who took their last dose of PPI before bed, the timing of the breakthrough period was between 1-4 am! Of couse this is adult data not pediatric, but I found it so interesting because so many of our refluxers have early morning wakeup issues from discomfort. They suggest using an H2 blocker for these times.
Anyhow, here’s the link. You can read it yourself.
