OTC antacids may modestly improve glucose in type 2 diabetes
Add-on proton pump inhibitor therapy improved glycemic markers among adults with type 2 diabetes, but did not alter risk for incident diabetes, according to a meta-analysis published in The Journal of Clinical Endocrinology & Metabolism.

Whether proton pump inhibitors (PPI) can improve glycemic control among individuals with diabetes or decrease the risk of incident diabetes in the general population is unclear.

This study aimed to evaluate the impact of PPI therapy on glycemic control among individuals with diabetes and the risk of diabetes among those without diabetes.

PubMed, Embase, Scopus, and ClinicalTrials.gov were searched and included studies comparing glycosylated hemoglobin (HbA1c) or fasting blood glucose (FBG) among individuals with diabetes treated with and without PPI therapy as an add-on to standard therapy. Studies evaluating the risk of incident diabetes among individuals taking PPI were assessed. They performed dual independent review, data extraction, and quality assessment. Weighted mean differences between groups or relative risks were imputed using random-effects models.

-- Seven studies (n?=?342) for glycemic control and 5 studies (n?=?244 439) for risk of incident diabetes were included.

-- Compared with standard therapy, add-on PPI was associated with a significant decrease in HbA1c and FBG.

-- PPI use did not reduce the risk of incident diabetes.

Conclusively, add-on PPI improved glycemic indices among individuals with diabetes but did not alter the risk of incident diabetes. The effects of PPI on glycemic control should be considered when prescribing antacids to patients with diabetes.
