Why are PPI taken before meals?

No further acid will be produced until the stomach manufactures additional acid-producing enzymes. The timing of taking the medication 30 to 60 minutes before eating a meal permits the maximum effect of the medication in the inhibiting of the production of gastric acid.

Is omeprazole absorption affected by food?

Food affected the pharmacokinetics of omeprazole (increased Tmax and decreased AUC and Cmax), pantoprazole (increased Tmax and decreased AUC), and rabeprazole (increased Tmax, Cmax and half-life). Food increased variability in Tmax for all 3 drugs, delaying absorption around 3 to 4 h and until 20 h in some subjects.

What is the problem with proton pump inhibitors?

The most common side effects reported include headache, diarrhea, nausea, and vomiting. Reports of more serious side effects include kidney disease, fractures, infections and vitamin deficiencies, but these are very rare and are generally associated with long-term use (using these products for more than a year).

Although PPIs have had an encouraging safety profile, recent studies regarding the long-term use of PPI medications have noted potential adverse effects, including risk of fractures, pneumonia, Clostridium difficile diarrhea, hypomagnesemia, vitamin B12 deficiency, chronic kidney disease, and dementia.
